Angioplasty, Balloon, Coronary: Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.Angioplasty, Balloon: Use of a balloon catheter for dilation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of BALLOON DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.Coronary Angiography: Radiography of the vascular system of the heart muscle after injection of a contrast medium.Coronary Vessels: The veins and arteries of the HEART.Coronary Disease: An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.Recurrence: The return of a sign, symptom, or disease after a remission.Coronary Artery Bypass: Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.Angioplasty: Reconstruction or repair of a blood vessel, which includes the widening of a pathological narrowing of an artery or vein by the removal of atheromatous plaque material and/or the endothelial lining as well, or by dilatation (BALLOON ANGIOPLASTY) to compress an ATHEROMA. Except for ENDARTERECTOMY, usually these procedures are performed via catheterization as minimally invasive ENDOVASCULAR PROCEDURES.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Phosphodiesterase 3 Inhibitors: Compounds that specifically inhibit PHOSPHODIESTERASE 3.Muscle, Smooth, Vascular: The nonstriated involuntary muscle tissue of blood vessels.Milrinone: A positive inotropic cardiotonic agent with vasodilator properties.

Milrinone is a derivative of amrinone and has 20-30 times the inotropic potency of amrinone.Cyclic Nucleotide Phosphodiesterases, Type 3: A cyclic nucleotide phosphodiesterase subfamily that is inhibited by the binding of CYCLIC GMP to an allosteric domain found on the enzyme and through phosphorylation by regulatory kinases such as PROTEIN KINASE A and PROTEIN KINASE B. The two members of this family are referred to as type 3A, and type 3B, and are each product of a distinct gene. In addition multiple enzyme variants of each subtype can be produced due to multiple alternative mRNA splicing.Cells, Cultured: Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.TetrazolesCoronary Restenosis: Recurrent narrowing or constriction of a coronary artery following surgical procedures performed to alleviate a prior obstruction.Phosphodiesterase Inhibitors: Compounds which inhibit or antagonize the biosynthesis or actions of phosphodiesterases.Stents: Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.IndiaDrug-Eluting Stents: Stents that are covered with materials that are embedded with chemicals that are gradually released into the surrounding milieu.Angioplasty, Balloon, Laser-Assisted: Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.Atherectomy: Endovascular procedure in which atheromatous plaque is excised by a cutting or rotating catheter. It differs from balloon and laser angioplasty procedures which enlarge vessels by dilation but frequently do not remove much plaque. If the plaque is removed by surgical excision under general anesthesia rather than by an endovascular procedure through a catheter, it is called ENDARTERECTOMY.Atherectomy, Coronary: Percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries.

Geographic, demographic, and socioeconomic variations in the investigation and management of coronary heart disease in Scotland. (1/6088)

OBJECTIVE: To determine whether age, sex, level of deprivation, and area of residence affect the likelihood of investigation and treatment of patients with coronary heart disease. DESIGN, PATIENTS, AND INTERVENTIONS: Routine discharge data were used to identify patients admitted with acute myocardial infarction (AMI) between 1991 and 1993 inclusive. Record linkage provided the proportion undergoing angiography, percutaneous transluminal coronary angioplasty (PTCA), and coronary artery bypass grafting (CABG) over the following two years. Multiple logistic regression analysis was used to determine whether age, sex, deprivation, and area of residence were independently associated with progression to investigation and revascularisation. SETTING: Mainland Scotland 1991 to 1995 inclusive. MAIN OUTCOME MEASURES: Two year incidence of angiography, PTCA, and CABG. Results-36 838 patients were admitted with AMI. 4831 (13%) underwent angiography, 587 (2%) PTCA, and 1825 (5%) CABG. Women were significantly less likely to undergo angiography (p < 0.001) and CABG (p < 0.001) but more likely to undergo PTCA (p < 0.05). Older patients were less likely to undergo all three procedures (p < 0.001). Socioeconomic deprivation was associated with a reduced likelihood of both angiography and CABG (p < 0.001). There were significant geographic variations in all three modalities (p < 0.001). CONCLUSION: Variations in investigation and management were demonstrated by age, sex, geography, and socioeconomic deprivation. These are unlikely to be accounted for by differences in need; differences in clinical practice are, therefore, likely.  (+info)

Usefulness of fractional flow reserve to predict clinical outcome after balloon angioplasty. (2/6088)

BACKGROUND: After regular coronary balloon angioplasty, it would be helpful to identify those patients who have a low cardiac event rate. Coronary angiography alone is not sensitive enough for that purpose, but it has been suggested that the combination of optimal angiographic and optimal functional results indicates a low restenosis chance. Pressure-derived myocardial fractional flow reserve (FFR) is an index of the functional severity of the residual epicardial lesion and could be useful for that purpose. METHODS AND RESULTS: In 60 consecutive patients with single-vessel disease, balloon angioplasty was performed by use of a pressure instead of a regular guide wire. Both quantitative coronary angiography (QCA) and measurement of FFR were performed 15 minutes after the procedure. A successful angioplasty result, defined as a residual diameter stenosis (DS) <50%, was achieved in 58 patients. In these patients, DS and FFR, measured 15 minutes after PTCA, were analyzed in relation to clinical outcome. In those 26 patients with both optimal angiographic (residual DS by QCA /=0.90) results, event-free survival rates at 6, 12, and 24 months were 92+/-5%, 92+/-5%, and 88+/-6%, respectively, versus 72+/-8%, 69+/-8%, and 59+/-9%, respectively, in the remaining 32 patients in whom the angiographic or functional result or both were suboptimal (P=0.047, P=0.028, and P=0.014, respectively). CONCLUSIONS: In patients with a residual DS /=0.90, clinical outcome up to 2 years is excellent. Therefore, there is a complementary value of coronary angiography and coronary pressure measurement in the evaluation of PTCA result.  (+info)

Coronary angioplasty induces rise in Chlamydia pneumoniae-specific antibodies. (3/6088)

Chlamydia pneumoniae is frequently found in atherosclerotic lesions, and high titers of specific antibodies are associated with increased risk for acute myocardial infarction. However, a causative relation has not been established yet. We performed a prospective study of 93 patients undergoing percutaneous transluminal coronary angioplasty (PTCA) to investigate whether angioplasty influences Chlamydia-specific antibody titers and whether there is an association with restenosis. Blood samples were obtained before and 1 and 6 months after angioplasty. Antibodies against chlamydial lipopolysaccharide and against purified C. pneumoniae elementary bodies were measured by enzyme-linked immunosorbent assay (ELISA). After angioplasty, the prevalence of antibodies to lipopolysaccharide rose from 20 to 26% for immunoglobulin A (IgA), from 53 to 64% for IgG, and from 2 to 7% for IgM (P = 0.021, 0.004, and 0.046, respectively). There was a rapid increase of mean antibody titers of all antibody classes within 1 month of PTCA. During the following 5 months, antibody titers decreased slightly but were still higher than baseline values. Results of the C. pneumoniae-specific ELISA were essentially the same. The rise of anti-Chlamydia antibodies was not caused by unspecific reactivation of the immune system, as levels of antibodies against cytomegalovirus did not change. Neither seropositivity nor antibody titers were related to restenosis. However, increases in mean IgA and IgM titers were restricted to patients who had suffered from myocardial infarction earlier in their lives. In conclusion, we show that PTCA induces a stimulation of the humoral immune response against C. pneumoniae. These data support the idea that plaque disruption during angioplasty might make hidden chlamydial antigens accessible to the immune system.  (+info)

A randomized placebo-controlled trial of fluvastatin for prevention of restenosis after successful coronary balloon angioplasty; final results of the fluvastatin angiographic restenosis (FLARE) trial. (4/6088)

BACKGROUND: The 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors competitively inhibit biosynthesis of mevalonate, a precursor of non-sterol compounds involved in cell proliferation. Experimental evidence suggests that fluvastatin may, independent of any lipid lowering action, exert a greater direct inhibitory effect on proliferating vascular myocytes than other statins. The FLARE (Fluvastatin Angioplasty Restenosis) Trial was conceived to evaluate the ability of fluvastatin 40 mg twice daily to reduce restenosis after successful coronary balloon angioplasty (PTCA). METHODS: Patients were randomized to either placebo or fluvastatin 40 mg twice daily beginning 2-4 weeks prior to planned PTCA and continuing after a successful PTCA (without the use of a stent), to follow-up angiography at 26+/-2 weeks. Clinical follow-up was completed at 40 weeks. The primary end-point was angiographic restenosis, measured by quantitative coronary angiography at a core laboratory, as the loss in minimal luminal diameter during follow-up. Clinical end-points were death, myocardial infarction, coronary artery bypass graft surgery or re-intervention, up to 40 weeks after PTCA. RESULTS: Of 1054 patients randomized, 526 were allocated to fluvastatin and 528 to placebo. Among these, 409 in the fluvastatin group and 427 in the placebo group were included in the intention-to-treat analysis, having undergone a successful PTCA after a minimum of 2 weeks of pre-treatment. At the time of PTCA, fluvastatin had reduced LDL cholesterol by 37% and this was maintained at 33% at 26 weeks. There was no difference in the primary end-point between the treatment groups (fluvastatin 0.23+/-0.49 mm vs placebo 0.23+/-0.52 mm, P=0.95) or in the angiographic restenosis rate (fluvastatin 28%, placebo 31%, chi-square P=0.42), or in the incidence of the composite clinical end-point at 40 weeks (22.4% vs 23.3%; logrank P=0.74). However, a significantly lower incidence of total death and myocardial infarction was observed in six patients (1.4%) in the fluvastatin group and 17 (4.0%) in the placebo group (log rank P=0.025). CONCLUSION: Treatment with fluvastatin 80 mg daily did not affect the process of restenosis and is therefore not indicated for this purpose. However, the observed reduction in mortality and myocardial infarction 40 weeks after PTCA in the fluvastatin treated group has not been previously reported with statin therapy. Accordingly, a priori investigation of this finding is indicated and a new clinical trial with this intention is already underway.  (+info)

Prior cytomegalovirus infection and the risk of restenosis after percutaneous transluminal coronary balloon angioplasty. (5/6088)

BACKGROUND: Restenosis is a common problem after all revascularization procedures in atherosclerotic coronary arteries. Reactivated human cytomegalovirus (CMV) has been detected in tissues of restenotic vascular lesions and was hypothesized to be a contributing pathogenic factor. Recent data suggest an association of restenosis after optimal coronary atherectomy with CMV serostatus, and a possible role of antiviral therapy was discussed. We therefore tested the hypothesis that prior CMV infection might be a risk factor for restenosis after conventional coronary balloon angioplasty (PTCA). METHODS AND RESULTS: We analyzed 92 consecutive patients who had been admitted for control angiography after previous PTCA within a mean interval of 6 months. Anti-CMV antibodies were measured as an indicator of prior CMV infection and latency. The coronary angiograms before PTCA, directly after, and 6 months later were analyzed quantitatively. Sixty-five percent of the patients were CMV-positive. Before PTCA, the degree (mean+/-SD) of stenosis was 69+/-10% in CMV-positive and 68+/-8.3% in CMV-negative subjects. PTCA resulted in a residual stenosis of 39% in both groups. After 6 months, the late losses of luminal diameter in the CMV-positive and -negative groups were 11+/-13% and 12+/-15%, respectively (P=0.658). In an ANCOVA with 25 potential risk factors for restenosis, CMV serostatus was not significantly associated with restenosis development. CONCLUSIONS: Our data indicate that prior CMV infection, in contrast to optimal atherectomy, is not associated with chronic restenosis after conventional coronary balloon angioplasty. The results do not support a possible benefit from antiviral therapy.  (+info)

Validation of an automated technique for determining the mechanical characteristics of coronary arteries during balloon angioplasty: laboratory assessment with necropsy segments. (6/6088)

OBJECTIVES: To develop a technique for automatic inflation of a percutaneous transluminal coronary angioplasty (PTCA) balloon, with continuous measurement of the balloon pressure and volume; to validate the technique for determining the mechanical characteristics of coronary arteries. METHODS: During necropsy examination of the hearts of nine patients, 17 coronary artery samples were obtained for histological examination. A PTCA balloon was inserted into each artery, and the balloon pressure and volume were measured continuously during four repeat automatic inflations of the balloon. RESULTS: Of the 17 arteries, eight showed elastic, six plastic, and three fracture pressure-volume deformation characteristics. For the plastic deformations, the first inflation required a higher pressure than subsequent repeat inflations of 82 (61) kPa (mean (SD), range 25 to 175 kPa). For the three in the fracture group, the pressure drop because of the fracture occurred between 210 and 540 kPa. Two of these three showed a tear on visual inspection, and the other showed disruption of the intimal plaque on blinded histological examination. Of the six with plastic deformation characteristics alone, one showed a tear, and on histological examination two others showed splitting of the internal and external elastic lamina and one showed separation of intima and media. None in the elastic group showed any of these characteristics. CONCLUSIONS: Plastic and fracture deformation characteristics could be differentiated from elastic characteristics. Visual or histological evidence of fracturing was present in all three arteries identified during angioplasty as having pressure-volume fracture characteristics.  (+info)

Primary angioplasty versus systemic thrombolysis in anterior myocardial infarction. (7/6088)

OBJECTIVES: This study compares the efficacy of primary angioplasty and systemic thrombolysis with t-PA in reducing the in-hospital mortality of patients with anterior AMI. BACKGROUND: Controversy still exists about the relative benefit of primary angioplasty over thrombolysis as treatment for AMI. METHODS: Two-hundred and twenty patients with anterior AMI were randomly assigned in our institution to primary angioplasty (109 patients) or systemic thrombolysis with accelerated t-PA (111 patients) within the first five hours from the onset of symptoms. RESULTS: Baseline characteristics were similar in both groups. Primary angioplasty was independently associated with a lower in-hospital mortality (2.8% vs. 10.8%, p = 0.02, adjusted odds ratio 0.23, 95% confidence interval 0.06 to 0.85). During hospitalization, patients treated by angioplasty had a lower frequency of postinfarction angina or positive stress test (11.9% vs. 25.2%, p = 0.01) and less frequently underwent percutaneous or surgical revascularization after the initial treatment (22.0% vs. 47.7%, p < 0.001) than did patients treated by t-PA. At six month follow-up, patients treated by angioplasty had a lower cumulative rate of death (4.6% vs. 11.7%, p = 0.05) and revascularization (31.2% vs. 55.9%, p < 0.001) than those treated by t-PA. CONCLUSIONS: In centers with an experienced and readily available interventional team, primary angioplasty is superior to t-PA for the treatment of anterior AMI.  (+info)

Long-term outcome after primary angioplasty: report from the primary angioplasty in myocardial infarction (PAMI-I) trial. (8/6088)

OBJECTIVES: This study sought to compare the two-year outcome after primary percutaneous coronary angioplasty or thrombolytic therapy for acute myocardial infarction. BACKGROUND: Primary angioplasty, that is, angioplasty without antecedent thrombolytic therapy, has been shown to be an effective reperfusion modality for patients suffering an acute myocardial infarction. This report reviews the two-year clinical outcome of patients randomized in the Primary Angioplasty in Myocardial Infarction trial. METHODS: At 12 clinical centers, 395 patients who presented within 12 h of the onset of myocardial infarction were randomized to undergo primary angioplasty (195 patients) or to receive tissue-type plasminogen activator (t-PA) (200 patients) followed by conservative care. Patients were followed by physician visits, phone call, letter and review of hospital records for any hospital admission at one month, six months, one year and two years. RESULTS: At two years, patients undergoing primary angioplasty had less recurrent ischemia (36.4% vs. 48% for t-PA, p = 0.026), lower reintervention rates (27.2% vs. 46.5% for t-PA, p < 0.0001) and reduced hospital readmission rates (58.5% vs. 69.0% for t-PA, p = 0.035). The combined end point of death or reinfarction was 14.9% for angioplasty versus 23% for t-PA, p = 0.034. Multivariate analysis found angioplasty to be independently predictive of a reduction in death, reinfarction or target vessel revascularization (p = 0.0001). CONCLUSIONS: The initial benefit of primary angioplasty performed by experienced operators is maintained over a two-year follow-up period with improved infarct-free survival and reduced rate of reintervention.  (+info)

Successful percutaneous transluminal coronary angioplasty (PTCA) was performed on a 37-year-old white man with an isolated 95% right coronary artery stenosis who initially presented with type II unstable angina. Submaximal treadmill stress testing was not carried out before PTCA, but testing 3 days after PTCA was strongly positive without accompanying symptoms of myocardial ischaemia. Some 30 minutes after this test the patient experienced severe precordial pain with features of a hyperacute transmural inferior myocardial infarction. Immediate coronary arteriography delineated fresh thrombus related to the previous PTCA site. Intracoronary thrombolysis with streptokinase was successful, revealing an underlying severe stenosis at the PTCA site. PTCA was not repeated, nor was emergency coronary artery bypass grafting (CABG) performed. This is the second such case documented in the literature; the first patient failed to respond to intracoronary thrombolysis with streptokinase and was submitted to ...
Coronary dissection and total coronary occlusion leading to emergency coronary surgery are the most frequent complications of percutaneous transluminal coronary angioplasty (PTCA) and their occurrence usually is unpredictable. To identify angiographic characteristics of coronary stenoses that may affect the incidence of these complications, the diagnostic pre-PTCA coronary angiograms of 38 consecutive patients (group I) undergoing emergency coronary surgery for dissection or occlusion were reviewed and compared with the angiograms of a random sample of 38 patients (stratified for left anterior descending and right coronary arteries) from a group of 1151 who did not need emergency coronary surgery (group II). Stenosis morphology before angioplasty was considered "complicated" if at least one of the following criteria was present: irregular borders, intraluminal lucency, and localization of stenosis in curve or at bifurcation. Baseline characteristics, maximum inflation pressures, types of balloon ...
To evaluate the long-term efficacy of percutaneous transluminal coronary angioplasty (PTCA) and alternative angioplasty devices in patients with coronary heart disease. There are four registries. The first registry followed 3,079 patients who received PTCA between 1977 and 1982. The second registry followed 1,500 patients from the first registry for a minimum of five years and followed 2,000 newly entered patients who received PTCA in 1985 and 1986 so that the second cohort would also be followed for five years. The third registry, the New Approaches to Coronary Intervention (NACI), followed approximately 4,424 patients between November 1990 and February 1997. The dynamic evaluation study will follow a total of 6,000 procedures ...
The main purpose of this study is to observe the incidence of major adverse cardiac and cerebrovascular events (MACCE), target vessel failure (TVF), target vessel revascularization (TVR) and stent thrombosis out to 5 years after the procedure in patients who underwent percutaneous coronary intervention (PCI) with everolimus-eluting stents for unprotected left main coronary artery (ULMCA) disease and lesions involving the ULMCA in Japan.

Early RHs carry a significant economic burden,12 and reducing the number of RHs by improving quality of care specifically in patients at high risk could lend to a better utilization of resources. Notwithstanding, such an undertaking may turn out complex. For instance, early physician follow‐up have not been associated with lower 30‐day RH rates in patients discharged after non‐STEMI.22. Baseline and procedural characteristics associated with unplanned RHs vary based on whether the cause of RH is cardiac or noncardiac. Interestingly, comorbidities, such as hypertension, previous stroke or transient ischemic attack, history of malignancy, and anemia, were associated only with unplanned noncardiac RHs, whereas lower left ventricular systolic function and higher MI Syntax score were associated only with unplanned cardiac RHs. A common characteristic of patients being readmitted for both cardiac and noncardiac reason was a significantly lower LDL level measured before initialization of statin ...

Transluminal coronary angioplasty was successfully performed in 658 of 752 patients with multivessel disease. An angiographic success was achieved in 1198 of 1358 lesions (88%). One lesion was attempted in 338 patients (45%); 2 in 273 (37%); 3, in 10
Background: Angiographic outcomes after percutaneous coronary intervention (PCI) for stent thrombosis (ST) have not been reported. In this study, we compared angiographic outcomes after PCI for ST between the timing of ST occurrence and between additional stenting and balloon angioplasty.. Methods: From January 2001 to October 2011, 152 patients (161 lesions) underwent PCI for definite ST. Of these patients, 134 patients (139 lesions) have survived to discharge, and we compared angiographic results between early, late, and very late ST and between addional stenting and balloon angioplasty. Angiographic follow-up was scheduled from 6 to 8 months after PCI by coronary angiography, but was performed earlier if ischemia was indicated clinically. Target lesion revascularization (TLR) was evaluated at 1 year after PCI for ST.. Results: Angiographic follow-up was performed in 113 lesions (81.3%). Serial quantitative coronary angiographic results are shown in the table. Very late ST had significantly ...
AIMS: Restenosis after percutaneous coronary angioplasty remains an important limitation of this procedure. This study evaluates whether elevated total plasma homocysteine levels contribute to the development of restenosis after coronary angioplasty.
OBJECTIVE: To evaluate the effect of the waiting time for elective percutaneous transluminal coronary angioplasty (PTCA) on the primary success rate. SETTING: University hospital in The Netherlands. PATIENTS: A cohort of 817 consecutive patients awaiting elective PTCA. Scheduled PTCA was performed in all 817 patients, involving 1237 coronary lesions. MAIN OUTCOME MEASURES: The relation between procedural success and the duration of the waiting time was evaluated. Major cardiac events, that is, death and myocardial infarction while awaiting PTCA, were documented. Alterations in lesion characteristics during the waiting time were assessed in unsuccessful procedures. RESULTS: Elective PTCA was performed within one to six weeks after acceptance in 388 patients (587 lesions; 47.5%), between six and 12 weeks in 203 patients (308 lesions; 25%), and after more than 12 weeks in 226 patients (342 lesions; 27.5%). The procedural success rates in the defined time intervals were 97%, 99%, and 97% in ACC/AHA ...
Primary percutaneous coronary intervention (PCI) is currently the preferred revascularization strategy in acute trasmural myocardial infarction (AMI). In this setting, about one half of patients will be diagnosed with concomitant multivessel (MV) coronary artery disease, associated with a multitude of negative prognostic factors but also still an independent predictor of adverse cardiac events and increased long-term mortality. Since additional "angiographic" lesions found at primary PCI are not directly responsile for the acute presentation, their treatment represents a difficult decision-making problem in cardiology. The article summarizes available clinical data on treatment in this setting and also review our current understanding of short-term progression of atherosclerosis after AMI.. ...

Background/objectives: Endothelial progenitor cells (EPCs) are circulating mononuclear cells that are released from the bone marrow in response to injury and participate in vascular repair. Some previous studies have suggested an early mobilisation of EPCs following percutaneous coronary intervention (PCI) that could modulate the subsequent risk of restenosis or stent thrombosis. However, those studies did not discriminate between vascular injury caused by PCI and any associated myocardial injury. Myocardial injury alone can influence EPC mobilisation in a non-specific manner, and could therefore confound any association with risk. We investigated the effect of local endothelial trauma following PCI on EPC mobilisation in the absence of myocyte necrosis.. Design: We quantified circulating EPCs from 20 patients immediately before, 6 hours and 24 hours following elective PCI in patients without a 24-hour troponin rise. Absolute counts of EPCs expressing combinations of CD45, CD34, CD133 and kinase ...
MODEL RELEASED. Coronary angioplasty. Surgeon performing a coronary angioplasty procedure on a 50-year-old man. This procedure opens blocked or narrowed coronary arteries, helping to prevent a heart attack. A catheter (narrow wire) has been inserted (centre left) into a groin artery. Use of an X-ray machine (upper right) and an injection of contrast medium, highlights the coronary arteries on an X-ray screen (far right). This aids the surgeon as he passes the catheter and a stent (an expandable tube) through the bodys arteries into a narrowed coronary artery in the heart. Inflation of the catheters balloon tip expands the stent to widen and strengthen the artery. Photographed at the American Hospital of Paris, France. - Stock Image M560/0521
Percutaneous coronary intervention (PCI) is a non-surgical procedure used to treat narrowing (stenosis) of the coronary arteries of the heart found in coronary artery disease. After accessing the blood stream through the femoral or radial artery, the procedure uses coronary catheterization to visualise the blood vessels on X-ray imaging. After this, an interventional cardiologist can perform a coronary angioplasty, using a balloon catheter in which a deflated balloon is advanced into the obstructed artery and inflated to relieve the narrowing; certain devices such as stents can be deployed to keep the blood vessel open. Various other procedures can also be performed. Primary PCI is the very urgent use of PCI in people with acute myocardial infarction (heart attack), especially where there is evidence of severe heart damage on the electrocardiogram (ST elevation MI). PCI is also used in people after other forms of myocardial infarction or unstable angina where there is a high risk of further ...
Laser balloon angioplasty (LBA) is a technique for improving the post angioplasty result by the radial diffusion of continuous wave Neodymium:YAG laser energy to the arterial wall during the final inflation of percutaneous transluminal coronary angioplasty (PTCA). Potential mechanisms of luminal improvement include sealing of dissections, reduction of arterial recoil, desiccation of thrombus, and reduction of thrombogenicity of tissues at the luminal surface. These effects are helpful in the management of failed PTCA as defined by the presence of a greater than 50% stenosis after conventional PTCA. Preliminary data suggest that LBA may be safe and effective for the treatment of abrupt closure, with a majority of patients successfully avoiding emergency coronary artery bypass surgery. Similarly, a cohort in which the residual post-PTCA luminal diameter was less than 50% of reference diameter (n=13) was subsequently treated with LBA and demonstrated uniform success in improving luminal diameter, ...
Istanbul, Turkey - 20 October 2012: Coronary angioplasty improves survival in all patients with out of hospital cardiac arrest, according to research presented at the Acute Cardiac Care Congress 2012. The study was presented by Dr Annamaria Nicolino from the Santa Corona General Hospital in Pietra Ligure, Italy.. The Acute Cardiac Care Congress 2012 is the first annual meeting of the newly launched Acute Cardiovascular Care Association (ACCA) of the European Society of Cardiology (ESC). It takes place during 20-22 October in Istanbul, Turkey, at the Istanbul Lufti Kirdar Convention and Exhibition Centre (ICEC).. Out of hospital cardiac arrest is a leading cause of mortality and acute coronary occlusion is the leading cause of cardiac arrest. It is well known that when an electrocardiogram (ECG) shows that a patient has ST elevation, primary angiography must be done as soon as possible. If severe coronary disease is found, coronary angioplasty with percutaneous coronary intervention (PCI) is ...
Chest pain following successful percutaneous coronary interventions is a common problem. Although the development of chest pain after coronary interventions may be of benign character, it is disturbing to patients, relatives and hospital staff. Such pain may be indicative of acute coronary artery closure, coronary artery spasm or myocardial infarction, but may also simply reflect local coronary artery trauma. The distinction between these causes of chest pain is crucial in selecting optimal care.Management of these patients may involve repeat coronary angiography and additional intervention. Commonly, repeat coronary angiography following percutaneous transluminal coronary angioplasty (PTCA) in patients with chest pain demonstrates widely patent lesion sites suggesting that the pain was due to coronary artery spasm, coronary arterial wall stretching or was of non-cardiac origin. ...
BACKGROUND The aim of this study was to evaluate the role of remote ischemic postconditioning (RIPC) of the upper arm on protection from cardiac ischemia-reperfusion injury following primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). MATERIAL AND METHODS Eighty patients with STEMI were randomized into two groups: primary PCI (N=44) and primary PCI+RIPC (N=36). RIPC consisted of four cycles of 5 minutes of occlusion and five minutes of reperfusion by cuff inflation and deflation of the upper arm, commencing within one minute of the first PCI balloon dilatation ...
AIMS: Primary percutaneous coronary intervention (PPCI) is the optimal treatment for patients presenting with ST-elevation myocardial infarction (STEMI). An elevated index of microcirculatory resistance (IMR) reflects microvascular function and when measured after PPCI, it can predict an adverse clinical outcome. We measured coronary microvascular function in STEMI patients and compared sequential changes before and after stent implantation. METHODS AND RESULTS: In 85 STEMI patients, fractional flow reserve, coronary flow reserve, and IMR were measured using a pressure wire (Certus, St Jude Medical, St Paul, MN, USA) immediately before and after stent implantation. Stenting significantly improved all of the measured parameters of coronary physiology including IMR from 67.7 [interquartile range (IQR): 56.2-95.8] to 36.7 (IQR: 22.7-59.5), P | 0.001. However, after stenting, IMR remained elevated (|40) in 28 (32.9%) patients. In 15 of these patients (17.6% of the cohort), only a partial reduction in IMR

Coronary artery restenosis after balloon angioplasty occurs in 30% to 50% of patients. More than 50 randomized trials have failed to show a successful pharmacologic intervention, and the first 2 trials with directional atherectomy (1, 2) produced equivocal results. In these 2 stent trials, the angiographic results were remarkably similar for both post-procedural and follow-up minimum luminal diameter and percent diameter stenosis. Each showed an absolute 10% reduction in angiographic restenosis with stenting, a significant advance in this field. The clinical outcome results can be interpreted in various ways. A more negative analysis than that presented by the authors can be summarized by tabulating the results for stenting rather than angioplasty in 100 patients. In the Benestent study, 10 patients were spared repeat angioplasty at a cost of 1 extra acute coronary artery closure, 2 more bypass operations, 10 extra bleeding or vascular complications, and 540 additional acute hospital days. The ...
I read yesterday morning that I was now a party to "The Great Coronary Angioplasty Debate." (Note to self: dont look at Twitter before Sunday brunch.). This all started a week ago, when Dr. Nortin Hadler posted an op-ed piece on The Health Care Blog, titled "The End of the Era of Coronary Angioplasty." He opined that angioplasty was unnecessary in the setting of a major heart attack (a.k.a. STEMI) and might even worsen outcomes. His title and thesis was so over-the-top (intentionally so, Im sure) that I felt obliged to pen a response to his very anti-stent article.. So now, he has posted a response to my response. I guess thats a debate….. In any case, the fact is that emergency angioplasty (primary PCI) has been shown to save heart muscle and lives in all the trials and studies that have been done over the past two decades. These are numbers, hard facts, not a priori or conjecture. Yes, it must be done quickly, which is why every PCI-capable hospital in the U.S. has been working for years ...
Patients who have multivessel coronary artery disease now have a wealth of information on the outcomes of treatment. The study by Hlatky and colleagues provides an excellent discussion of the costs and outcomes of 2 interventions, PTCA and CABG. These data were developed from a substudy of the Bypass Angioplasty Revascularization Investigation (BARI) study. The study showed that patients who have PTCA have lower initial treatment costs and return to work faster than do patients who have CABG. However, during 5 years of follow-up, the initial advantages diminish for patients with 2-vessel disease and are nonexistent for patients with 3-vessel disease or diabetes. In fact, the BARI study showed that patients with diabetes had a survival advantage with CABG. Discussion of the survival results of the BARI study has appeared elsewhere (1). The study by Hlatky and colleagues provides more extensive information than earlier studies on the quality of life and costs of these 2 treatment strategies. Based ...
When Andreas Grüntzig introduced percutaneous transluminal coronary angioplasty (PTCA) in 1977, he thought that embolisation may be induced, but he found no wash out of plaque material into the distal coronary artery in experimental studies. Using PTCA a rise of cardiac markers was noticed only rarely, despite the fact that ECG recordings detected ST-T segment changes in a larger group of patients. The systemic determination of the new cardiac markers troponin T or I and the introduction of coronary stenting, as well as rotational angioplasty in percutaneous coronary intervention (PCI), led to a 5- to 10-fold increase of cases with so called "infarctlets".14,15 The prevalence of these laboratory findings was higher in patients with unstable than stable angina (34% v 10%), higher in patients after stenting than after PTCA (22% v 4%), and higher after recanalisation than after angioplasty of coronary stenosis. In patients undergoing coronary rotational angioplasty the highest percentage of ...

The main findings of this single-center study are: 1) there was still no difference at a median of 61.9 months (IQR: 57.8 to 67.2 months) in the occurrence of MACCE between elective PCI with DES implantation and CABG for ULMCA disease; 2) the benefit of PCI in the composite end point of cardiac death, MI, and cerebrovascular events that we reported at 1 year was still present at a longer term clinical follow-up; and 3) the advantage of CABG was confirmed in the lower need for repeated revascularization. According to current guidelines, the treatment of ULMCA disease with PCI has a Class IIb indication (1). Some retrospective studies evaluating surgical treatment for this disease reported an in-hospital mortality rate varying from 1.7% to 7.0% and a 1-year mortality rate of 6% to 14% (18-21).. Encouraging 1-year and more recently 3-year results have been reported for PCI with DES implantation in this particular subset of patients (2-11). Observational, nonrandomized registries (5,13,16) reported ...
New research confirms thrombus aspiration (TA) during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) provides long-term outcomes similar to conventional intervention with bare-metal or drug-eluting stents. Findings published in a special STEMI-focused issue of Catheterization and Cardiovascular Interventions, a journal of the Society for Cardiovascular Angiography and Interventions (SCAI), report that compared to conventional PCI, thrombectomy does not affect rates of major adverse cardiac events at two-year follow-up. The World Health Organization (WHO) reports that cardiovascular diseases are the number one cause of death worldwide, and by 2030 nearly 24 million people will die, primarily from heart disease and stroke. PCI, known also as angioplasty, is used to open blocked arteries to restore blood flow and more than one million Americans have this procedure each year according to the National Heart, Lung, and Blood ...
After the procedure, you may be taken to the recovery room for observation or returned to your hospital room. You will remain flat in bed for several hours after the procedure. A nurse will monitor your vital signs, the insertion site, and circulation or sensation in the affected leg or arm.. You should immediately inform your nurse if you feel any chest pain or tightness, or any other pain, as well as any feelings of warmth, bleeding, or pain at the insertion site in your leg or arm.. Bedrest may vary from two to six hours depending on your specific condition. If your doctor placed a closure device, your bedrest may be of shorter duration.. In some cases, the sheath or introducer may be left in the insertion site. If so, the period of bedrest will be prolonged until the sheath is removed. After the sheath is removed, you may be given a light meal.. You may feel the urge to urinate frequently because of the effects of the contrast dye and increased fluids. You will need to use a bedpan or urinal ...
The drug-eluting balloon (DEB) is a device that is used to reduce the risk of repeat stent implantation in patients with in-stent restenosis (ISR) (1). Characterization of tissue by optical coherence tomography (OCT) may provide useful information to identify good candidates for DEBs (2). However, the image visualized by OCT just after DEB dilation is unclear. We present images after DEB dilation visualized by OCT.. A 45-year-old man was treated with a bare metal stent (BMS) (S-stent 4.0/23.0 mm) implanted in the right coronary artery (RCA) for acute ST-segment elevation myocardial infarction. After percutaneous coronary intervention (PCI), he was taking 100 mg of aspirin and 75 mg of clopidogrel. However, a second coronary angiography at 6 months after BMS implantation showed ISR in the BMS. A repeat PCI was performed for ISR in the RCA. After the guide wire was advanced to the distal portion of the RCA, the target lesion was dilated using a 4.0/13.0 mm scoring balloon catheter (Lacrosse ...
Although recent data show that coronary stenting reduces procedural complications and late restenosis, major concern has been expressed about the greater hospital cost associated with the use of this device as compared to conventional coronary angioplasty. Since length of hospital stay after surgical procedures is a major determinant of resource use, the identification of variables associated with an excessively long hospital stay after intracoronary stent placement may have important practical consequences. The purpose of this study was to assess factors responsible for the occurrence of in-hospital complications and prolonged hospital stay after coronary stenting in 939 consecutive patients enrolled in the Registro Impianto Stent Endocoronarico (RISE Study Group). Consecutive patients undergoing coronary stent implantation at 16 medical centers in Italy were prospectively enrolled in the Registry. Clinical data, qualitative and quantitative angiographic findings were obtained from data collected in
Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is a nonsurgical procedure that improves blood flow to your heart.
For some people, medications and lifestyle changes may be the treatment of choice.. In other cases, angioplasty - also known as percutaneous coronary intervention - may be recommended to open the clogged arteries. Angioplasty may especially be recommended if you are having chest discomfort (angina) due to reduced blood flow that has not responded to medication and lifestyle changes.. During angioplasty, your doctor inserts a tiny balloon at the site of the blockage and expands it to widen the narrowed artery. Your doctor then may implant a small metal coil (stent) in the clogged artery to keep the artery open and reduce the risk of it narrowing again. Its possible you may even have angioplasty during your cardiac catheterization, if your doctor thinks its the most appropriate treatment option for you.. If your arteries are narrowed or blocked in multiple areas, or your left main coronary artery is narrowed, your doctor may recommend coronary bypass surgery. Some studies show coronary bypass ...

Your heart has been mended, but its not like before." About 45 million people in India suffer from coronary artery disease each year, most of them in the age bracket of early forties to late seventies. Tiny blood vessels supplying the heart and providing it with nutrition either thicken or get clogged up with clots and fatty deposits, slowly diminishing in their capacity to function properly.. Angioplasty or percutaneous transluminal coronary angioplasty (PTCA) is a temporary technique used to widen the coronary arteries by placing a stent (a small, expandable tube) in the area of blocked vessel to enable blood circulation to the heart.. The word angioplasty is derived from Greek words angio meaning vessel and plasticos meaning "fit for moulding." The rate of performing angioplasty surgeries in India has increased by about 42% in 2015. This is indeed a dismal situation where people are increasingly seeking treatment for a condition whose origins are based in our faulty lifestyles.. Unhealthy ...
A percutaneous coronary intervention (PCI) is often called balloon angioplasty. A catheter is inserted into the blood vessels either in the groin (femoral artery) or in the arm (radial artery). Using a special type of X-ray called fluoroscopy; the catheter is threaded through the blood vessels into the heart where the coronary artery is narrowed. […]. ...
In the EUROMAX trial, the overall incidence of AST was low (0.6%), but the risk was higher among patients randomized to bivalirudin. This is in keeping with similar observations from HORIZONS-AMI. Although the absolute number of AST cases was small, thereby precluding the definitive assessment of associated factors, EUROMAX provided additional information on AST in the setting of contemporary pPCI. Importantly, EUROMAX confirmed that the risk period for AST appears to be limited to the first few hours after pPCI despite the fact that the Academic Research Consortium definition encompasses the first 24 h.. There were 2 distinct treatment strategies incorporated in the EUROMAX trial that had the potential to mitigate the risk of excess AST, namely, the extended infusion of bivalirudin and the use of the newer P2Y12 inhibitors. According to the results of this analysis, neither the use of prasugrel or ticagrelor, nor a prolonged low-dose bivalirudin infusion were able to reduce the AST risk. ...
Several investigators (16,22)found that symptomatic status is related to the severity of the recurrent lesion. Others (35-37)observed no such correlation. Minimal lumen diameter rather than stenosis severity may be more predictive of angina (34). Some have found that neither angina status before PCI (22,37,38)nor diabetes mellitus (16,22,34,37,38)is correlated with symptomatic status. The converse was noted by others (9). Both the presence (22)and absence (16)of unstable angina at presentation, and both younger (36)and older age (15)have been associated with asymptomatic restenosis. Because no meta-analysis of the interaction among clinical and angiographic factors and symptomatic status has been performed, there is no reliable method of predicting which patients are most at risk of developing asymptomatic restenosis and silent ischemia following PCI. Using a logistic regression model, Zellweger et al. (38)found that the only independent predictor of silent ischemia after coronary stenting was a ...
Percutaneous coronary intervention had her humble beginnings in 1977 in Zurich when Dr A Greuntzig, under flouroscopy guidance passed a very high profile and crude catheter ( rubber tubing ) with a balloon at the distal end. Once across the lesion ( which was at the proximal LAD ), he inflated the balloon repeatedly, until the lesion ws flattened and there was no longer any more pressure gradient across the lesion. The patient was a dentist, and the simple balloon angioplasty lasted him about 15 years ...

You may not always be able to choose between having a coronary angioplasty or a CABG, but if you are its important to be aware of the advantages and disadvantages of each technique.. As a coronary angioplasty is minimally invasive, youll recover from the effects of the operation quicker than you will from a CABG. Coronary angioplasty usually has a smaller risk of complications, but theres a chance youll need further treatment because the affected artery may narrow again.. However, the number of people who need further surgery has fallen because of the use of drug-eluting stents. See how a coronary angioplasty is performed for more information about these.. CABG has a longer recovery time than coronary angioplasty and a higher risk of complications. However, only one person in 10 who has a CABG requires further treatment. Also, some evidence suggests that CABG is usually a more effective treatment option for people who are over 65 years of age and particularly for people with diabetes.. You ...
The region surrounding the balloon utilized in percutaneous transluminal coronary angioplasty is heated by means within the balloon or within the skin of the balloon upon inflation of the balloon such that disrupted tissues of the plaque in the arterial wall are heated in order to fuse together fragmented segments of tissue and to coagulate blood trapped within dissected planes of tissue and within fissures created by wall fracture such that upon subsequent balloon deflation a smooth cylindrically-shaped channel results, thereby to prevent collapse of any flap of material which could cause either abrupt arterial closure and an acute myocardial infarction or gradual restenosis at the site of balloon inflation.

Although the SYNTAX trial stratified randomization according to the presence of left main disease and prespecified the left main subgroup as a secondary analysis, Boudriot et al. (6) performed a small, multicenter, randomized trial dedicated to patients with significant (,50%) left main disease. The goal of the trial was to assess whether PCI with sirolimus-eluting stents would be noninferior to CABG with respect to the rate of the combined endpoint of death, MI, and repeat revascularization. Patients who had chronic total occlusions, lesions ,30 mm, and "extreme" left-dominant coronary systems were excluded. A total of 201 patients were enrolled, providing 80% power assuming a 15% event rate in the surgical group and an allowable relative risk difference of 10% between groups. Enrolled patients had lower anatomic and surgical risk compared with those in the SYNTAX trial: the mean SYNTAX score was 23.5, the mean logistic EuroSCORE was 2.5, and 14% had concomitant 3-vessel disease. A median of 2 ...

Despite the clinical advantage of percutaneous transluminal coronary angioplasty (PTCA) in treating severely narrowed blood vessels, long-term success is often compromised by restenosis. It is unclear what mechanisms cause vessels to renarrow, despite numerous studies involving patients and experimental animal models of arterial injury. Although neointimal thickening was initially considered the major cause, recent evidence suggests that arterial constriction, adventitial thickening, or both may be critical in the restenosis process. The geometric changes of vessel expansion and contraction constitute the definition of remodeling. The present emphasis on remodeling and restenosis has been driven by studies failing to show a direct correlation between neointimal thickening and lumen size, suggesting that intimal mass alone is insufficient to explain narrowing.1 Analyses of human coronary angioplasty sites at autopsy by our laboratory support the thesis that constrictive remodeling and the initial ...
Angioplasty opens up blockages in the arteries around the heart and improves blood flow. Although still considered a surgical procedure, since there is an opening made in the skin, angioplasty is easier on the person than coronary bypass surgery.

A total of 140 age-matched men and women were included in the study between January 2011 and January 2012. Baseline characteristics were similar in men and women, with the exception of lower body surface area and TIMI risk score (median: 4 vs. 3, p < 0.001) in women versus men. Time from symptom onset to arrival in the catheterization laboratory was shorter in men than in women. Men and women had similar rates of plaque rupture (50.0% vs. 48.4%; risk ratio [RR], 1.03; 95% confidence interval [CI], 0.73-1.47; p = 0.56). Nonruptured or eroded plaques comprised 25% of all cases (p = 0.86 in men vs. women). There were no sex differences in composition of aspirated thrombus and immune and inflammatory serum biomarkers. At 9 months, women had similar strut coverage (90.9% vs. 92.5%; difference in medians: RR, 0.2%; 95% CI, -0.4% to 1.3%; p = 0.89) and amount of in-stent neointimal obstruction (10.3% vs. 10.6%; p = 0.76) as the men.

The Tp-e/QT ratio was correlated with both short- and long-term outcomes. Analysis of the receiver operating characteristic curve demonstrated that the optimal cutoff value for outcome prediction was a Tp-e/QT ratio of 0.29. Of the 388 patients enrolled, 115 (34.0%) exhibited a Tp-e/QT ratio ≥0.29. Patients with a Tp-e/QT ratio ≥0.29 showed elevated rates of both in-hospital death (21.9% vs 2.3%; P , 0.001) and main adverse cardiac events (MACE) (48.1% vs 15.3%; P , 0.005). After discharge, Tp-e/QT ratios ≥0.29 remained an independent predictor of all-cause death (35.5% vs 5.2%, P , 0.001) and cardiac death (32.3% vs 2.6%, P , 0.001). ...

Angioplasty and related techniques are known as percutaneous coronary intervention (PCI). Angioplasty is a procedure in which a narrowed section of the coronary artery is dilated with a balloon catheter. Angioplasty is less invasive and has a shorter recovery time than bypass surgery, which is also done to increase blood flow to the heart muscle but requires open - heart surgery. Most of the time

Downloadable! We analyse referral patterns for patients undergoing percutaneous transluminal coronary angioplasty (PTCA) in the Emilia Romagna region of Italy, a procedure for which the assumption of a negative association between volume and adverse outcomes is used to justify its territorial concentration. Nevertheless, recent clinical evidence shows PTCA superiority for immediate treatment of acute myocardial infarction, which advises an increase in the number of points of delivery. Our paper aims to develop analytical tools designed to provide support to policy makers when they are asked to evaluate the spatial distribution of catheterisation laboratories that perform PTCA. Information is drawn from the regional administrative hospital discharge data (SDO) for the year 2002. We first use entropy indexes to investigate the spatial accessibility of the cardiological network. Secondly, by means of a gravity model estimated using Bayesian techniques we identify the determinants of patient flows in terms
Patients who undergo bypass surgery for heart disease have better long-term survival rates than those who opt for less invasive procedures like angioplasty, a major US study showed on Tuesday.. The study looked at data from 190,000 US patients and found that those who had bypass surgery had a lower death rate in the first four years (16.4 percent) compared to those who had angioplasty (20.8 percent).. Bypass operations involve open heart surgery to create a detour around a blocked artery using a vein taken from somewhere else in the patients body.. The type of angioplasty examined in the study, known as percutaneous coronary intervention (PCI), involves a small incision to thread a balloon, a wire stent or a tube through the blocked artery to keep it open.. "Our study is the most general one ever done because it uses data from across the whole country. It is also much larger than any other study", said William Weintraub, chair of cardiology at Christiana Care Health System and the studys lead ...

As Dr. Robert Harrington, Chief of Medicine at Stanford University, describes:. "Every patient case became a rather detailed discussion around what was best. And remember the days of cath conferences where there would be much discussion and even heated debate amongst interventional cardiologists, non-invasive cardiologists and our surgical colleagues about what might be the appropriate approach for that particular patient.". Then came stents: metal scaffolds that had the ability to hold the artery open after the balloon inflation. Soon the complications of angioplasty that resulted in emergency bypass surgery became one in a thousand or less. The procedure became much safer. So much so that it became feasible, even desirable, to add another 30 minutes or so onto the diagnostic procedure and open up the blockage. One stop shopping…or stenting: ad hoc angioplasty!. What was gained was efficiency, less patient discomfort, lower costs…what was lost was that period of decision-making, of debate ...
Coronary angioplasty is a commonly used therapy to remove stenoses in patients with chronic stable angina. Although a successful procedure, there remain both the short-term (stent thrombosis and vessel injury) and long-term risks (late stent thrombosis and significant in-stent restenosis) such that indiscriminate use of stenting can be deleterious. A considerable body of evidence suggests clinical outcomes are improved when stenting is performed using invasive coronary physiology; if stenoses cause ischaemia revascularisation is preferential to deferment, while non-ischaemic stenoses may be treated with medical therapy and observation. Successfully treated vessels are less likely to have major cardiovascular events and patient events are improved. However, there remains no good way of readily and practically predicting whether placing a stent will be successful with normalisation of abnormal coronary physiology. Furthermore, there remains no good parameter to delineate the length of a stenoses ...

Coronary angioplasty is a potentially complex type of procedure that requires specialist staff and equipment, and not all hospitals have the facilities.. This means youll need to be taken urgently, by ambulance, to one of the specialist centres (Heart Attack Centres) that now serve most of the UKs regions.. During coronary angioplasty, a tiny tube known as a balloon catheter, with a sausage-shaped balloon at the end, is put into a large artery in your groin or arm. The catheter is passed through your blood vessels and up to your heart, over a fine guidewire, using X-rays to guide it, before being moved into the narrowed section of your coronary artery.. Once in position, the balloon is inflated inside the narrowed part of the coronary artery to open it wide. A stent (flexible metal mesh) is usually inserted into the artery to help keep it open afterwards.. ...
A coronary angioplasty usually takes place in a room called a catheterisation laboratory, rather than in an operating theatre. This is a room fitted with X-ray equipment to allow the doctor to monitor the procedure on a screen.. A coronary angioplasty usually takes between 30 minutes and two hours, although it can take longer.. Youll be asked to lie on your back on an X-ray table. Youll be linked up to a heart monitor and given a local anaesthetic to numb your skin. An intravenous (IV) line will also be inserted into a vein, in case you need to have painkillers or a sedative. The cardiologist then makes a small incision in the skin of your groin, wrist or arm, over an artery where your pulse can be felt. A small tube called a sheath is inserted into the artery to keep it open during the procedure.. A catheter is passed through the sheath and guided along the artery into the opening of your left or right coronary artery.. A thin, flexible wire is then passed down the inside of the catheter to ...

In some cases, mechanically opening the blocked arteries may be required or recommended. The two most common of these procedures are:. Percutaneous coronary intervention (PCI) -A small balloon attached to a catheter is inserted into an artery in the groin and threaded to the site of blockage. The balloon is inflated and deflated to open the artery, and then it is removed. This makes more room in the artery for blood to flow through. Frequently a metal stent is also placed to help keep the artery open. Some new stents are coated with medication to help prevent renarrowing of the artery, called restenosis. ...

According to data from randomized, controlled trials, primary percutaneous coronary intervention (PCI) is the treatment of choice for ST-segment elevation myocardial infarction (MI). In these trials, 1 life was saved and 2 other life-threatening complications, including stroke and reinfarction, were prevented for every 50 patients with ST-segment elevation MI treated with primary PCI rather than thrombolytic therapy. Only 1 major bleeding episode occurred.. How can these superior results be realized outside the context of randomized trials? We anticipate 4 obstacles to instituting primary PCI as the universal treatment of ST-segment elevation MI: 1) lack of timely availability, 2) technical expertise of center and operator, 3) the need to address patient subgroups that are not studied in randomized trials, and 4) comparisons of primary PCI to newer pharmacologic regimens.. We propose 3 strategies to increase the availability of this procedure: 1) perform primary PCI in qualified community ...

BACKGROUND: Patients with obstructive left main coronary artery disease are usually treated with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug-eluting stents may be an acceptable alternative to CABG in selected patients with left main coronary disease. METHODS: We randomly assigned 1905 eligible patients with left main coronary artery disease of low or intermediate anatomical complexity to undergo either percutaneous coronary intervention (PCI) with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients). Anatomic complexity was assessed at the sites and defined by a Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score of 32 or lower (the SYNTAX score reflects a comprehensive angiographic assessment of the coronary vasculature, with 0 as the lowest score and higher scores [no upper limit] indicating more complex coronary anatomy). The primary end point was
The use of Coronary Artery Bypass Grafting (CABG) rather than Percutaneous Coronary Intervention (PCI) for the management of patients with triple vessel or left main coronary artery disease is associated with lower rates of major adverse cardiac or cerebrovascular events at 1 year. The conclusion is based on a trail (STNTAX trail) published in New England Journal of Medicine March 2009 edition.. The SYNTAX (Synergy between PCI with taxus and cardiac surgery) trail, conducted in United States and several countries in Europe, involved 1800 patients with previously untreated triple vessel disease or left main coronary artery disease. The patients were randomly assigned to undergo CABG or PCI and were monitored for the subsequent 12 month period for any major cardiac or cerebrovascular event. Death from any cause, stroke, myocardial infarction and repeat revascularization were considered as major adverse events. The research was sponsored by Boston Scientific, developer of the drug eluting taxus ...
Coronary angiography remains the gold standard for imaging coronary anatomy and defining the extent and precise location of coronary artery disease. Optimal coronary angiography is dependent on a thorough knowledge of coronary anatomy and a systematic imaging sequence protocol that enables visualization of all coronary segments, particularly areas of vessel overlap, bifurcations, or tortuous anatomy. A basic map of the coronary anatomy is delineated in Figure 69-1, and the optimal views for imaging each coronary segment are summarized in Table 69-1 (Figs. 69-2, 69-3, 69-4, 69-5). Although standard views are generally consistent from one patient to the next, the precise angulations tend to vary based on the variations in anatomic orientations. A number of coronary segment numbering systems have been established; the most commonly used is the Coronary Artery Surgery Study (CASS) numbering system derived from the Bypass Angioplasty Revascularization Investigation (BARI) study,1 which assigns a ...

A 47-year-old man was emergently referred from another tertiary care center for percutaneous coronary intervention to the left main coronary artery (LM). Diagnostic coronary angiography (CAG) indicated a critical stenosis at the LM ostium (Fig. 1A, arrow) and haziness in the proximal to mid-left anterior descending coronary artery (LAD) (Fig. 1A, dotted line). Intravascular ultrasound showed a heavy plaque burden at the LM ostium (Fig. 1B). Emergent stent implantation was performed with a Resolute Integrity 4.0- × 12-mm stent (Medtronic Vascular, Santa Rosa, California) from the ostium to the mid-body of the LM. Because the chest pain was not relieved after stenting, optical coherence tomography (OCT) (C7-XR system, C7 Dragonfly catheter, LightLab Imaging, St. Jude, Minneapolis, Minnesota) was done to more accurately assess the thrombotic lesion in the proximal to mid-LAD. Longitudinal OCT images clearly showed the intimal-medial dissection in the thrombotic LAD lesion. In cross-sectional OCT ...
OBJECTIVES: We used optical coherence tomography, which has a resolution of |20 microm, to analyze thin layers of neointima in rapamycin-eluting coronary stents. BACKGROUND: Lack of neointimal coverage has been implicated in the pathogenesis of drug-eluting coronary stent thrombosis. Angiography and intracoronary ultrasound lack the resolution to examine this. METHODS: We conducted a randomized trial in patients receiving polymer-coated rapamycin-eluting stents (Cypher, Cordis, Johnson & Johnson, Miami, Florida) and nonpolymer rapamycin-eluting stents (Yukon, Translumina, Hechingen, Germany) to examine neointimal thickness, stent strut coverage, and protrusion at 90 days. Twenty-four patients (n = 12 for each group) underwent stent deployment and invasive follow-up at 90 days with optical coherence tomography. The primary end point was binary stent strut coverage. Coprimary end points were neointimal thickness and stent strut luminal protrusion. RESULTS: No patient had angiographic restenosis. For
