A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc.

The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
Surgical excision, performed under general anesthesia, of the atheromatous tunica intima of an artery. When reconstruction of an artery is performed as an endovascular procedure through a catheter, it is called ATHERECTOMY.
Unstable isotopes of thallium that decay or disintegrate emitting radiation. Tl atoms with atomic weights 198-202, 204, and 206-210 are thallium radioisotopes.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
The use of balloon CATHETERS to remove emboli by retraction of the balloon that is inflated behind the EMBOLUS.
Artery arising from the brachiocephalic trunk on the right side and from the arch of the aorta on the left side. It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.
A branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters.
Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.
The flow of BLOOD through or around an organ or region of the body.

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 ...

BACKGROUND: This study is the third in a series of investigations on the requisite length of time that patients should be restricted to bed after coronary arteriography or percutaneous transluminal coronary angioplasty using a femoral artery approach. METHODS: A prospective, experimental-control group design with randomization was used initially to compare the incidence of bleeding between patients who remained in bed for 4 hours and patients who remained in bed for 6 hours after sheath removal following percutaneous transluminal coronary angioplasty. RESULTS: Rapid changes in the healthcare environment led to nurses collecting complete data sets for the experimental group only. The experimental group (n = 51) was 73% male and 27% female; mean age was 57 years (SD = 11.4 years). Mean time in bed was 4.1 hours (SD = 0.27 hours). Most patients (98%) did not bleed from the femoral artery access site after remaining in bed for 4 hours following sheath removal. Ninety-two percent of patients required ...
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 ...

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 ...

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 ...
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 ...
BACKGROUND: Adverse cardiac event rates are higher for percutaneous coronary intervention (PCI) of bifurcation lesions. Currently, provisional stenting or a simple stenting strategy is the standard treatment for bifurcated lesions, but its performance remains limited because of a risk of side-branch (SB) closure and a higher rate of target lesion revascularization (TLR). We report a new provisional side-branch stenting strategy to treat coronary bifurcation lesions using a balloon-stent kissing technique (BSKT).. METHODS: From January 2011 to December 2012, a total of 60 patients with 60 bifurcation lesions underwent PCI using BSKT. Baseline and postprocedural quantitative coronary angiography (QCA) analyses were performed. Procedural and immediate clinical outcomes were reviewed.. RESULTS: The majority of patients presented with acute coronary syndrome (98%) and had true bifurcation lesions (98%). TIMI-3 flow was established in 100% of the main branch and SB lesions. QCA revealed preservation ...
The CVIs Cardiac Catherization Laboratory offers elective angioplasty such as stenting as well as around-the-clock availability of primary percutaneous transluminal coronary angioplasty (PTCA), a common procedure to reopen clogged or damaged coronary arteries.
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.. ...

In-hospital and late outcome of rescue versus primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction
In the past ten years, primary percutaneous coronary intervention (PCI) has replaced thrombolysis as the revascularisation strategy for many patients presenting with ST-segment elevation myocardial infarction (STEMI). However, delivery of primary PCI
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
Intracoronary epinephrine in the treatment of refractory no-reflow after primary percutaneous coronary intervention: a retrospective study ...
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, ...
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 ...
Although coronary-artery bypass grafting (CABG) is the standard choice of revascularization for significant left main coronary artery (LMCA) disease, percutaneous coronary intervention (PCI) for LMCA disease has been widely expanded with adoption of drug-eluting stents (DES). Several small- and moderate-sized trials of CABG and first-generation DES showed that PCI might be a good alternative for selected patients with LMCA disease. However, these early trials were relatively underpowered and comparative results of contemporary DES and CABG were clearly required. Subsequently, two large-sized trials comparing CABG and contemporary DES (EXCEL and NOBLE) were conducted, but these trials showed conflicting results with regards to the effects of PCI and CABG on clinical outcomes, which raises further uncertainty on the optimal revascularization for LMCA disease. This article serves to summarize the key findings of landmark clinical trials, to share our knowledge and experience and to express personal
The aim of this study is to evaluate the effect of pre PCI administration of intracoronary nitroprusside on post procedural myonecrosis. Myonecrosis is a prognostically important complication of PCI. Nitric oxide is a potent vasodilator in the resistance arteriolar circulation, and plays a significant role in the control of coronary blood flow through the microcirculation. nitroprussideis a direct donor of nitric oxide. A total of 62 patients were randomized into the NTP (n= 31) or control (n= 31) group. Patients who were scheduled for non-urgent PCI in de novo native coronary arteries were eligible. All patients were pretreated with statin, aspirin and clopidogrel. Myonecrosis was measured by CK-MB elevation 24 h after PCI. The NTP group received intracoronary NTP befor PCI, whereas the control group did not. All patients in NPT group received NTP for prevention of myonecrosis at a dose of at least 50 μg given intrcoronary through guiding catheter. 22 patients received 50μg,7 patients ...
Scrubbing in for my first cardiac catheterization case as a first-year fellow was exciting enough, but the added exhilaration realizing it was a left main coronary artery (LMCA) PCI was almost too much to handle! We had been taught in medical school that LMCA disease was treated only by CABG.. However, with significant advancements in the field of interventional cardiology, PCI of left main disease has evolved to have comparable outcomes with CABG in selected patients.. Background. The first LMCA PCI was performed by Andreas Gruentzig, MD, FACC, in 1978 with plain old balloon angioplasty. Subsequently, bare metal stent technology has been used and, in the contemporary era, drug-eluting stents (DES.) Adjunctive tools such as intravascular imaging with IVUS and mechanical cardiovascular support have also emerged as important tools when considering a LMCA PCI strategy.1-5. Prominent Trials Addressing LMCA PCI. SYNTAX was a landmark study comparing LMCA PCI using first-generation DES with CABG.6 The ...

Abstract:Acute coronary syndromes and, in paticular, ST - segment elevation myocardial infarction are the principle causes or mortality and morbidity in the industrialized countries. The manadgement of acute myocadial infarction is much debated in the literature; primary percutaneous coronary intervention is the treatment of choice.

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 ...

Post-marketing surveillance (PMS) may identify rare serious incidents or adverse events due to the long-term use of a medical device, which was not captured in the pre-market process. Percutaneous transluminal coronary angioplasty (PTCA) is a non-surgical procedure that uses a balloon-tipped catheter to enlarge a narrowed artery. In 2011, 1,942 adverse event reports related to the use of PTCA catheters were submitted to the FDA by the manufacturers, an increase from the 883 reported in 2008. The primary research objective is to conduct a systematic review of the published and grey literature published between 2007 and 2012 for the frequency of incidents, adverse events and malfunctions associated with the use of PTCA catheters in patients with coronary artery disease (CAD). Grey literature has not been commercially published. We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and PubMed for medical literature on PMS for PTCA catheters in patients with CAD published between

In the United States, ULMCA PCI is performed primarily in patients with a high burden of comorbidities and frequently in those with high-urgency clinical presentations. In this population, in-hospital mortality was substantially higher in those with ULMCA disease who were treated percutaneously; however, this early risk is driven by those with high-urgency, rather than lower-urgency, presentations.. Among ULMCA patients selected for PCI in the United States, 30-month mortality is high (42.7%), with a predominance of cardiovascular events. These findings are especially notable when compared to the 10% mortality reported at 30 months in the MAIN-COMPARE (Korean Revascularization for Unprotected Left Main Coronary Artery Stenosis: Comparison of Percutaneous Coronary Angioplasty Versus Surgical Revascularization) study (11), and the 4% mortality reported at 1 year in the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial (12).

BACKGROUND: Incomplete revascularisation is common after percutaneous coronary intervention and is associated with increased mortality and adverse cardiovascular events. We aimed to assess whether adjunctive anti-ischaemic pharmacotherapy with ranolazine would improve the prognosis of patients with incomplete revascularisation after percutaneous coronary intervention.. METHODS: We performed this multicentre, randomised, parallel-group, double-blind, placebo-controlled, event-driven trial at 245 centres in 15 countries in Europe, Israel, Russia, and the USA. Patients (aged ≥18 years) with a history of chronic angina with incomplete revascularisation after percutaneous coronary intervention (defined as one or more lesions with ≥50% diameter stenosis in a coronary artery ≥2 mm diameter) were randomly assigned (1:1), via an interactive web-based block randomisation system (block sizes of ten), to receive either twice-daily oral ranolazine 1000 mg or matching placebo. Randomisation was ...
Background In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. Methods Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. Results Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher ...

Background There are conflicting data on the clinical benefit from early administration of abciximab from a large randomized trial and a registry. However, both sources suggest that a benefit may depend on the baseline risk profile of the patients. We evaluated the role of early abciximab administration in patients with ST-segment-elevation myocardial infarction (STEMI) referred for primary percutaneous coronary intervention stratified by the STEMI Thrombolysis In Myocardial Infarction (TIMI) risk score. Methods A total of 1,650 patients were enrolled into the EUROTRANSFER Registry. One thousand eighty-six patients received abciximab (66%). Abciximab was administered early in 727 patients (EA) and late in 359 patients (LA). We used the TIMI risk score for risk stratification. Patients with scores 3 constituted the high-risk group of 616 patients (56.7%), whereas 470 patients formed the low-risk cohort. Factoring in the timing of the abciximab administration resulted in 4 groups of patients who ...
Background The efficacy and safety of ticagrelor following percutaneous coronary intervention for patients with acute coronary syndrome remains unclear. This study sought to evaluate clinical outcomes of ticagrelor as part of dual-antiplatelet treatment for these patients. Methods PubMed, MEDLINE, Embase, and other Internet sources were searched for eligible citations. The primary end point was major adverse cardiovascular and cerebrovascular events, consisting of cardiovascular death, myocardial infarction, and stroke. The secondary end point was the occurrence of definite/probable stent thrombosis (ST). The risk of bleeding was chosen to be the safety end point. Results Eleven clinical trials - six randomized trials and five observational trials - were finally analyzed. A tendency toward reduction in the risk of major adverse cardiovascular and cerebrovascular events was observed only with respect to ticagrelor (OR 0.83, 95% CI 0.66-1.03; P=0

Myocardial infarction (MI) remains the most common cause of heart failure (HF) worldwide. For almost 50 years HF has been recognised as a determinant of adverse prognosis after MI, but efforts to promote myocardial repair have failed to translate into clinical therapies. Primary percutaneous coronary intervention (PPCI) has driven improved early survival after MI, but its impact on the incidence of downstream HF is debated. The effects of PPCI are confounded by the changing epidemiology of MI and HF, with an ageing patient demographic, an increasing proportion of non-ST-elevation myocardial infarction, and the recognition of HF with preserved ejection fraction. Herein we review the mechanisms of HF after MI and discuss contemporary data on its incidence and outcomes. We review current and emerging strategies for early detection of patients at risk of HF after MI, with a view to identification of patient cohorts for novel therapeutic agents.
Background Glycated hemoglobin (HbA1c) predicts clinical cardiovascular disease or cardiovascular mortality. However, the relationship between HbA1c and myocardial injury following elective percutaneous coronary intervention (PCI) in patients with type 2 diabetes mellitus (DM) has not been investigated. Objectives The study sought to assess the relationship between HbA1c and myocardial injury following elective PCI in patients with type 2 DM. Methods We studied a cohort of consecutive 994 diabetic patients with coronary artery disease (CAD) undergoing elective PCI. Periprocedural myocardial injury was evaluated by analysis of troponin I (cTnI). The association between preprocedural HbA1c levels and the peak values of cTnI within 24 hours after PCI was evaluated. Results Peak postprocedural cTnI |1×upper limit of normal (ULN), |3×ULN and |5×ULN were detected in 543 (54.6%), 337 (33.9%) and 245 (24.6%) respectively. In the multivariate model, higher HbA1c levels were associated with less risk of

I read with interest the article entitled Comparison of Percutaneous Coronary Intervention With Bare-Metal and Drug-Eluting Stents for Cardiac Allograft Vasculopathy (1). This is an interesting study showing a lower in-stent restenosis rate of patients receiving drug-eluting stents (DES) for allograft vasculopathy. There are 2 major points that need clarification. The authors did not report any statistical analysis in regards to important end points such as death, myocardial infarction, or target vessel revascularization in each group. We have to assume that these very important end points, including re-transplantation, were similar between the groups. Death and re-transplantation occurred in 34% of the entire cohort with follow-up of ,1 year. This suggests poor prognosis of patients with significant allograft vasculopathy, regardless of stent types used. This is an important observation that needs to be emphasized. The second important point concerns a major dilemma that exists between ...

Objective: We hypothesised that, compared with culprit-only primary percutaneous coronary intervention (PCI), additional preventive PCI in selected patients with ST-elevation myocardial infarction with multivessel disease would not be associated with iatrogenic myocardial infarction, and would be associated with reductions in left ventricular (LV) volumes in the longer term. Methods: In the preventive angioplasty in myocardial infarction trial (PRAMI; ISRCTN73028481), cardiac magnetic resonance (CMR) was prespecified in two centres and performed (median, IQR) 3 (1, 5) and 209 (189, 957) days after primary PCI. Results: From 219 enrolled patients in two sites, 84% underwent CMR. 42 (50%) were randomised to culprit-artery-only PCI and 42 (50%) were randomised to preventive PCI. Follow-up CMR scans were available in 72 (86%) patients. There were two (4.8%) cases of procedure-related myocardial infarction in the preventive PCI group. The culprit-artery-only group had a higher proportion of anterior ...

Percutaneous coronary intervention (PCI) has traditionally been used as first-line therapy for limited coronary artery disease while coronary artery bypass grafting (CABG) has been the mainstay of therapy for patients with more advanced multivessel and left main disease. With the more frequent use of PCI in patients with advanced and complex disease, there is an increasing number of patients who present for CABG who have had previous PCI. A key factor in this PCI first approach must be that the outcome of CABG is not jeopardized by a prior PCI procedure(s). The question therefore is when a patient who has had a previous PCI presents for CABG, is that patient at higher risk for the surgical procedure and subject to worse long-term outcomes than a similar patient presenting for CABG who has not had previous PCI?. It is the general sense of most practicing cardiac surgeons that many patients with 1 or especially multiple previous PCIs who present for CABG are, in fact, worse candidates than they ...
