For the specific technique of BALLOON DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.Arteriosclerosis: Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.Myocardial Reperfusion Injury: 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.Aorta: The main trunk of the systemic arteries.Regional Blood Flow: The flow of BLOOD through or around an organ or region of the body.Randomized Controlled Trials as Topic: Works about clinical trials that involve at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.Aortic Valve: The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.Risk: The probability that an event will occur. It encompasses a variety of measures of the probability of a generally unfavorable outcome.Heart Failure: A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Geographic, demographic, and socioeconomic variations in the investigation and management of coronary heart disease in Scotland. (1/4803)

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)

Detection of Chlamydia pneumoniae but not cytomegalovirus in occluded saphenous vein coronary artery bypass grafts. (2/4803)

BACKGROUND: A causal relation between atherosclerosis and chronic infection with Chlamydia pneumoniae and/or cytomegalovirus (CMV) has been suggested. Whether the unresolved problem of venous coronary artery bypass graft occlusion is related to infection with C pneumoniae and/or CMV has not been addressed. METHODS AND RESUTLS: Thirty-eight occluded coronary artery vein grafts and 20 native saphenous veins were examined. Detection of C pneumoniae DNA was performed by use of nested polymerase chain reaction (PCR). Homogenisates from the specimen were cultured for identification of viable C pneumoniae. Both conventional PCR and quantitative PCR for detection of CMV DNA were applied. Differential pathological changes (degree of inflammation, smooth muscle cell proliferation [MIB-1]) were determined and correlated to the detection of both microorganisms. C pneumoniae DNA could be detected in 25% of occluded vein grafts. Viable C pneumoniae was recovered from 16% of occluded vein grafts. Except for 1 native saphenous vein, all control vessels were negative for both C pneumoniae detection and culture. All pathological and control specimens were negative for CMV DNA detection. Pathological changes did not correlate with C pneumoniae detection. CONCLUSIONS: Occluded aorto-coronary venous grafts harbor C pneumoniae but not CMV. The detection of C pneumoniae in occluded vein grafts warrants further investigation.  (+info)

New-onset sustained ventricular tachycardia after cardiac surgery. (3/4803)

BACKGROUND: The de novo occurrence of sustained ventricular tachycardia (VT) after CABG has been described, but the incidence, mortality rate, long-term follow-up, and mechanism are not well defined. METHODS AND RESULTS: This prospective study enrolled consecutive patients undergoing CABG at a single institution. Patients were followed up for the development of sustained VT, and a detailed analysis of clinical, angiographic, and surgical variables associated with the occurrence of VT was performed. A total of 382 patients participated, and 12 patients (3.1%) experienced >/=1 episode of sustained VT 4.1+/-4.8 days after CABG. In 11 of 12 patients, no postoperative complication explained the VT; 1 patient had a perioperative myocardial infarction. The in-hospital mortality rate was 25%. Patients with VT were more likely to have prior myocardial infarction (92% versus 50%, P<0.01), severe congestive heart failure (56% versus 21%, P<0.01), and ejection fraction <0.40 (70% versus 29%, P<0.01). When all 3 factors were present, the risk of VT was 30%, a 14-fold increase. Patients with VT had more noncollateralized totally occluded vessels on angiogram (1.4+/-0.97 versus 0.54+/-0.7, P<0.01), a bypass graft across a noncollateralized occluded vessel (1.50+/-1.0 versus 0.42+/-0.62, P<0.01), and a bypass graft across a noncollateralized occluded vessel to an infarct zone (1.50+/-1.0 versus 0.17+/-0.38, P<0.01). By multivariate analysis, the number of bypass grafts across a noncollateralized occluded vessel to an infarct zone was the only independent factor predicting VT. CONCLUSIONS: The first presentation of sustained monomorphic VT in the recovery period after CABG is uncommon, but the incidence is high in specific clinical subsets. Placement of a bypass graft across a noncollateralized total occlusion in a vessel supplying an infarct zone was strongly and independently associated with the development of VT.  (+info)

Renal failure predisposes patients to adverse outcome after coronary artery bypass surgery. VA Cooperative Study #5. (4/4803)

BACKGROUND: More than 600,000 coronary artery bypass graft (CABG) procedures are done annually in the United States. Some data indicate that 10 to 20% of patients who are undergoing a CABG procedure have a serum creatinine of more than 1.5 mg/dl. There are few data on the impact of a mild increase in serum creatinine concentration on CABG outcome. METHODS: We analyzed a Veterans Affairs database obtained prospectively from 1992 through 1996 at 14 of 43 centers performing heart surgery. We compared the outcome after CABG in patients with a baseline serum creatinine of less than 1.5 mg/dl (median 1.1 mg/dl, N = 3271) to patients with a baseline serum creatinine of 1.5 to 3.0 mg/dl (median 1.7, N = 631). RESULTS: Univariate analysis revealed that patients with a serum creatinine of 1.5 to 3.0 mg/dl had a higher 30-day mortality (7% vs. 3%, P < 0.001) requirement for prolonged mechanical ventilation (15% vs. 8%, P = 0.001), stroke (7% vs. 2%, P < 0.001), renal failure requiring dialysis at discharge (3% vs. 1%, P < 0.001), and bleeding complications (8% vs. 3%, P < 0.001) than patients with a baseline serum creatinine of less than 1.5 mg/dl. Multiple logistic regression analyses found that patients with a baseline serum creatinine of less than 1.5 mg/dl had significantly lower (P < 0.02) 30-day mortality and postoperative bleeding and ventilatory complications than patients with a serum creatinine of 1.5 to 3.0 mg/dl when controlling for all other variables. CONCLUSION: These results demonstrate that mild renal failure is an independent risk factor for adverse outcome after CABG.  (+info)

Combined carotid endarterectomy and coronary artery bypass graft. (5/4803)

Atherosclerosis is a generalized disease which afflicts a considerable number of patients in both the carotid and coronary arteries. Although the risk of stroke or death use to combined carotid endarterectomy (CEA) and coronary artery bypass graft (CABG) is thought to be higher than that of each individual operation, the combined procedure is generally preferred over staged operations to treat such patients. We performed the combined procedure safely with the aid of intraoperative portable digital subtraction angiography (DSA). This report describes our experience with the operative strategy of simultaneous CEA and CABG. Ninety CEA and 404 CABG were carried out between January 1989 and December 1997. A total of six patients received the combined procedure with the aid of intraoperative DSA; they were studied retrospectively. Postoperative mortality and morbidity after the combined procedure was 0%. In the combined procedure, neurological complications are difficult to detect after CEA because the patient must be maintained under general anesthesia and extracorporeal circulation during the subsequent CABG. However, intraoperative DSA can confirm patency of the internal carotid artery and absence of flap formation after CEA, and the CABG can be performed safely. Intraoperative portable DSA between CEA and CABG is helpful in preventing perioperative stroke in the combined procedure.  (+info)

Cyclooxygenase-2 is widely expressed in atherosclerotic lesions affecting native and transplanted human coronary arteries and colocalizes with inducible nitric oxide synthase and nitrotyrosine particularly in macrophages. (6/4803)

Inflammation appears to have a major role in the development of atherosclerotic lesions affecting native and transplanted coronary arteries. The subsequent risk of plaque rupture and acute ischemic events correlates with the degree of inflammation and may be modified by aspirin, an anti-inflammatory cyclooxygenase inhibitor. Cyclooxygenase-2 (Cox-2) and inducible nitric oxide synthase (iNOS) are involved in the inflammatory response via the rapid and exaggerated production of prostanoids and nitric oxide, both of which may have proatherosclerotic effects. These effects may be mediated by the formation of peroxynitrite in the case of nitric oxide and involve "cross talk" between the two enzyme systems. This study aimed to investigate native and transplant atherosclerosis for the presence and distribution of Cox-2 and iNOS. Immunocytochemical studies were performed on atherosclerotic lesions from patients with native (n=12) and transplant (n=5) coronary disease by using antibodies to Cox-2, iNOS, and nitrotyrosine (an indicator of peroxynitrite production). Control tissue was obtained from unused donor hearts and at the time of autopsy. Cox-2 and iNOS colocalized predominantly in macrophages/foam cells in both types of atherosclerosis. Cox-2 expression was also detected in medial smooth muscle cells and endothelial cells, including those of the vasa vasorum. Nitrotyrosine was found in the same distribution as that of iNOS and was colocalized with Cox-2 in macrophages. Cox-2 and iNOS are coexpressed in native and transplant atherosclerosis, possibly allowing for interaction between the enzymes and suggesting an alternative mechanism for the benefits of aspirin via inhibition of Cox-2 activity.  (+info)

Contraction-relaxation coupling and impaired left ventricular performance in coronary surgery patients. (7/4803)

BACKGROUND: Dependence of left ventricular (LV) relaxation on cardiac systolic load is a function of myocardial contractility. The authors hypothesized that, if a tight coupling would exist between LV contraction and relaxation, the changes in relaxation rate with an increase in cardiac systolic load would be related to the changes in LV contraction. METHODS: Coronary surgery patients (n = 120) with preoperative ejection fraction >40% were included. High-fidelity LV pressure tracings (n = 120) and transgastric transesophageal echocardiographic data (n = 40) were obtained. Hearts were paced at a fixed rate of 90 beats/min. Effects on contraction were evaluated by analysis of changes in dP/dt(max) and stroke area. Effects on relaxation were assessed by analysis of R (slope of the relation between tau and end-systolic pressure). Correlations were calculated with linear regression analysis using Pearson's coefficient r. RESULTS: Baseline LV end-diastolic pressure was 10+/-3 mm Hg (mean +/- SD). During leg raising, systolic LV pressure increased from 93+/-9 to 107+/-11 mm Hg. The change in dP/dt(max) was variable and ranged from -181 to +254 mm Hg/s. A similar variability was observed with the changes in stroke area, which ranged from -2.0 to +5.5 cm2. Changes in dP/dt(max) and in stroke area were closely related to individual R values (r = 0.87, P<0.001; and r = 0.81, P<0.001, respectively) and to corresponding changes in LV end-diastolic pressure (r = 0.81, P< 0.001; and r = 0.74, P<0.001, respectively). CONCLUSIONS: A tight coupling was observed between contraction and relaxation. Leg raising identified patients who developed a load-dependent impairment of LV performance and increased load dependence of LV relaxation.  (+info)

Prognostic value of dobutamine stress echocardiography in predicting cardiac events in patients with known or suspected coronary artery disease. (8/4803)

OBJECTIVES: The study sought to determine the utility of dobutamine stress echocardiography (DSE) in predicting cardiac events in the year after testing. BACKGROUND: Increasingly, DSE has been applied to risk stratification of patients. METHODS: Medical records of 1,183 consecutive patients who underwent DSE were reviewed. The cardiac events that occurred during the 12 months after DSE were tabulated: myocardial infarction (MI), cardiac death, percutaneous transluminal coronary angioplasty (PTCA), and coronary artery bypass surgery (CABG). Patient exclusions included organ transplant receipt or evaluation, recent PTCA, noncardiac death, and lack of follow-up. A positive stress echocardiogram (SE) was defined as new or worsened wall-motion abnormalities (WMAs) consistent with ischemia during DSE. Classification and regression tree (CART) analysis identified variables that best predicted future cardiac events. RESULTS: The average age was 68+/-12 years, with 338 women and 220 men. The overall cardiac event rate was 34% if SE was positive, and 10% if it was negative. The event rates for MI and death were 10% and 8%, respectively, if SE was positive, and 3% and 3%, respectively, if SE was negative. If an ischemic electrocardiogram (ECG) and a positive SE were present, the overall event rate was 42%, versus a 7% rate when ECG and SE were negative for ischemia. Rest WMA was the most useful variable in predicting future cardiac events using CART: 25% of patients with and 6% without a rest WMA had an event. Other important variables were a dobutamine EF <52.5%, a positive SE, an ischemic ECG response, history of hypertension and age. CONCLUSIONS: A positive SE provides useful prognostic information that is enhanced by also considering rest-wall motion, stress ECG response, and dobutamine EF.  (+info)

TY - JOUR. T1 - Network meta-analysis of antiplatelet therapy following coronary artery bypass grafting (CABG). T2 - none versus one versus two antiplatelet agents. AU - Chakos, Adam. AU - Jbara, Dean. AU - Singh, Kamal. AU - Yan, Tristan D.. AU - Tian, David H.. PY - 2018/9/1. Y1 - 2018/9/1. N2 - Background: Numerous agents have been trialed following coronary artery bypass grafting (CABG) to maintain long-term graft patency. While clear evidence exists for the use of aspirin in maintaining graft patency, the role of dual-antiplatelet therapy in CABG patients is not as well established. This network meta-analysis aimed to compare the short-term post-CABG graft patency outcomes for patients with none, one or two antiplatelet agents. Methods: Electronic databases were queried for randomized controlled trials comparing CABG graft patency rates at three months and beyond using various antiplatelet agents or placebo. Drug and graft patency data were compared using a mixed treatment comparison under ...
Background: The SHOCK Trial demonstrated that early revascularization (ERV) provided a survival advantage compared with initial medical stabilization in patients with acute myocardial infarction (MI). The ideal revascularization strategy for patients with cardiogenic shock in the setting of left main coronary artery (LMCA) disease is unknown.. Methods: We compared 30-day survival rates associated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in this clinical setting. A multiple Cox regression model with left truncation was used to identify risk factors for 30-day mortality and attempt to correct for the bias that would be attributable to the differential time to revascularization.. Results: The SHOCK Trial (n=144) and Registry (=33) included 177 patients with significant (,50%) LMCA disease who underwent revascularization (CABG or PCI). Although the trial protocol recommended CABG for patients with LMCA involvement, the revascularization strategy (92 ...
An aneurysm is defined as dilatation of the artery greater than 50% in diameter. Aneurysms are categorized as fusiform or saccular. The saccular aneurysms of the ascending aorta are rarely seen and are usually life-threatening. Excessive use of biologicglue, graft infection, mediastinitis, aortic dissection, atherosclerosis, hypertension, degeneration of a penetrating atherosclerotic ulcer, poorsurgical technique, trauma, fungal infections and previous aortic surgery (presumably due to the cannulation site) are the etiologic risk factors for the development of a false or true aneurysm of the ascending aorta [1]. There are a few reports for saccular aneurysm of the ascending aorta which are following coronary artery bypass grafting surgery. The wall stressis greater in saccular aneurysms rather than fusiform aneurysms. The disruption of the vesse lwall at the cannulation site oral long the aortic suture lines lead to saccular aneurysm..

Researchers said that in comparison to coronary artery bypass patients who have normal weight, patients with extreme obesity were thrice more vulnerable to develop an infection post-bypass surgery. Through the coronary artery bypass surgery, blood flow is redirected to the heart surrounding clogged heart arteries.. The studys senior author, Mary Forhan, Ph.D., assistant professor at the University of Alberta in Edmonton, Canada, said, "Based on the results of this study it appears that addressing infection risk might be an effective strategy to decrease the length-of-stay for patients with obesity who undergo coronary artery bypass surgery".. The study used a Canadian database of heart patients, and analyzed how a racially and ethnically varied group of 7,560 patients fared following a bypass surgery in Edmonton in the years April 2003 to March 2014.. The division of the patients was done as per their body mass index into five different groups, including normal weight with BMI 18.5-24.9; ...
TY - JOUR. T1 - Predictors of inotropic support during weaning from cardiopulmonary bypass in coronary artery bypass grafting surgery. AU - Hayashi, H.. AU - Prabhu, R.. AU - Kramer, D. C.. AU - Oka, Y.. PY - 1997/4/15. Y1 - 1997/4/15. N2 - Early or prophylactic inotropic drug administration is occasionally required to facilitate separation from cardiopulmonary bypass (CPB) in cardiac surgery. However, it is not without untoward effects and should be conducted on the basis of rational criteria. The purpose of our study was to clarify variables associated with the requirement for inotropic support during separation from CPB and to testify whether pre-CPB left ventricular (LV) function, as evaluated by transesophageal echocardiography (TEE), is one of the significant variables. Clinical profile data and TEE findings were retrospectively analyzed for 91 patients who had received elective primary isolated coronary artery bypass grafting (CABG) surgery. Post-CPB inotropic drug administration ...
OBJECTIVES We sought to ascertain the utility of adenosine thallium-201 tomography for assessing graft stenoses late after coronary artery bypass graft surgery. BACKGROUND Although pharmacologic perfusion imaging has been increasingly used in the assessment of patients with coronary artery disease, the value of this stress modality for detecting coronary artery bypass graft stenosis late after surgery is unknown. METHODS We studied 109 patients who underwent both adenosine thallium-201 tomography and coronary angiography at 6.7 +/- 4.8 (mean +/- SD) years after coronary artery bypass graft surgery. Adenosine thallium-201 tomography was assessed quantitatively by computer-generated polar maps of the myocardial thallium-201 activity. RESULTS On coronary angiography, significant graft stenoses were present in 68 patients, 65 of whom had a corresponding perfusion defect as shown by thallium-201 tomography (sensitivity 96%). Significant stenoses were present in 107 (37.8%) of 283 grafts. The overall
Atrial fibrillation (AF) is a common complication after coronary artery bypass grafting. Atrial remodeling has been observed in AF and has been associated with the development of this arrhythmia. Because 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins) have been demonstrated to modify remodeling, we hypothesized a protective role of statins against postoperative AF. We also hypothesized that extracellular matrix turnover and brain natriuretic peptide (BNP) might be related to such atrial remodeling. We studied 234 consecutive patients who underwent coronary artery bypass grafting (173 men; 65 +/- 9 years of age) in whom the occurrence of postoperative AF was monitored. In a subgroup of 66 patients, we measured plasma levels of matrix metalloproteinase-1 (MMP-1), its inhibitor, tissue inhibitor matrix metalloproteinase-1 (TIMP-1; as indexes of extracellular matrix remodeling), and N-terminus pro-BNP (related to left ventricular function) at baseline and at 24 hours after surgery. Of 234 ...
New research shows that a minimally invasive approach used during coronary artery bypass grafting surgery is safe and effective, despite previous studies that linked endoscopic vein harvesting to a higher mortality rate. The research, published in the August 1, 2012 edition of The Journal of the American Medical Association, was an observational study of more than 235,000 patients included in The Society of Thoracic Surgeons National Database who underwent CABG surgery at 934 participating surgical centers. Investigators compared the three-year outcomes of patients undergoing EVH to the outcomes of patients undergoing the more invasive open vein harvesting (OVH) procedure and found no difference in mortality rates. "This study should alleviate concerns of patients and surgeons raised by past studies, and confirms the superiority of the EVH technique in terms of infection and wound complication rates that makes the minimally invasive approach the preferred method," said senior author Peter K. ...
OBJECTIVES The mechanisms of postoperative cognitive dysfunction in patients with diabetes after coronary artery bypass grafting are not fully understood. We sought to determine which type 2 diabetes-related factors contributed to postoperative cognitive dysfunction at 7 days and 6 months after coronary artery bypass grafting. METHODS One hundred eighty patients with type 2 diabetes who were scheduled for elective coronary artery bypass grafting were studied. As a control group, 100 patients without diabetes mellitus matched for age, sex, and educational level were examined. Hemodynamic parameters (arterial and jugular venous blood gas values) were measured during cardiopulmonary bypass. All patients underwent a battery of neurologic and neuropsychologic tests the day before surgery, 7 days after surgery, and 6 months after surgery. RESULTS Age (odds ratio 1.5, 95% confidence interval 1.3-1.8, P = .03), presence of hypertension (odds ratio 1.8, 95% confidence interval 1.3-2.0, P = .01), jugular

Between 2001 and 2008, the annual rate of coronary artery bypass graft surgeries performed in the United States decreased by more than 30 percent, but rates of percutaneous coronary interventions (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) did not change significantly, according to a study in the May 4 issue of JAMA.. "Coronary revascularization, comprising coronary artery bypass graft (CABG) surgery and PCI, is among the most common major medical procedures provided by the U.S. health care system, with more than 1 million procedures performed annually," according to background information in the article. Several innovations in coronary revascularization, such as drug-eluting stents (DES) and minimally invasive CABG surgery have been adopted widely in the past decade, with the promise of improved clinical outcomes compared with older revascularization technologies and techniques. "During this period of technological innovation, new ...
Main Research Question(s):. What is the effect of continuing aspirin until the time of coronary artery bypass graft surgery and of adding clopidogrel to aspirin after coronary artery bypass graft surgery for preventing blockage of coronary grafts, heart attack, stroke, and death? To reliably answer this question requires a large randomised trial. Before applying for a major grant from the Canadian Institute for Health Research to do the large study we would like to perform a small pilot study of 150 patients to demonstrate that it is feasible to recruit patients and to use a new test called CT angiography to determine whether the bypass grafts are still working or have become blocked.. (ii) Why is this research important? Coronary artery bypass surgery has made a very important contribution to improving the health and survival of patients with advanced coronary artery disease but still has many problems. One in 10 patients experiences a heart attack at the time of surgery, 1 in 20 experiences ...

The generalizability of a prediction model from North America for incident nosocomial pneumonia following coronary artery bypass graft surgery was assessed for 23247 patients on the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) registry. The performance of the North American model was evaluated using measures of calibration and discrimination. The model had reasonable discrimination (area under the receiver-operating characteristic curve, AUC=0·69), but unsatisfactory calibration (Hosmer-Lemeshow test, P,0·001) in the ANZSCTS patients. An update of the model coefficients yielded a model with AUC=0·71 and good calibration (P=0·46). © 2013 Cambridge University Press.. ...
Objective: The aim of this study was to investigate whether acute kidney injury (AKI) after coronary artery bypass grafting can be attributed to intraoperative hypotension during cardiopulmonary bypass (IOH-CPB). Design: Retrospective analysis. Setting: Tertiary-care hospital. Participants: Patients undergoing on-pump coronary artery bypass grafting from June 2011 to January 2014. Interventions: ... read more None. Measurements and Main Results: IOH-CPB was defined as blood pressure below several absolute and relative mean arterial pressure (MAP) thresholds and as the area under the curve for absolute MAP thresholds. AKI was defined as an absolute increase in serum creatinine of≥26 μmol/L within 48 hours or an increase to 150% or more within 7 days of surgery. Poisson regression with robust standard errors both before and after adjustment for confounders was used. Of the 1,891 patients included, 386 (20%) developed AKI. In univariable analysis, all IOH-CPB thresholds defined as a MAP of 50 ...
To evaluate the relative long-term improvement in coronary artery hemodynamics after revascularization by coronary artery bypass graft surgery (CABG) or percutaneous transluminal coronary angioplasty (PTCA), regional coronary flow reserve (CFR) was measured, by digital computer analysis of 35 mm cine film, in 50 men undergoing cardiac catheterization. CFR (mean +/- SEM) in 12 atherosclerotic arteries before revascularization was 1.02 +/- 0.05. Mean CFR in 29 normal arteries of men with normal coronary arteriograms was significantly higher (2.59 +/- 0.11) than that in 16 atherosclerotic arteries of patients revascularized by CABG (2.02 +/- 0.17, p less than .01) or in 14 atherosclerotic arteries of those revascularized by PTCA (1.97 +/- 0.12, p less than .01). No difference in CFR between the CABG and PTCA groups was found and variables known to influence CFR were similar between groups. Equivalent and significant long-term improvement in coronary artery hemodynamics is provided by CABG or PTCA. ...
We read with great interest the study by Hongo et al. (1)entitled "The Effect of Clopidogrel in Combination With Aspirin When Given Before Coronary Artery Bypass Grafting." This very interesting study highlights an emerging problem for patients having routine coronary artery bypass graft surgery (CABG) after percutaneous intervention, as described in their report, but also for patients with an acute coronary syndrome who require urgent "in-house surgery" because these patients are invariably on both clopidogrel and aspirin therapy.. In their study, the investigators showed that continued clopidogrel therapy within seven days of elective CABG results in increased blood loss, increased use of blood products, and increased re-exploration rates. Unfortunately, although the study was prospective there was no blinding of the nurses or clinicians to clopidogrel and aspirin exposure.. This lack of blinding is crucial to determine whether the main outcomes of the study are credible. The investigators ...
There are limitations to the conclusions that can be drawn from this study. Firstly, the comparisons we have made here are not an attempt to estimate either the effectiveness of coronary artery bypass surgery, or the relative balance of benefits and risks associated with early intervention for particular patients. There is clear evidence from randomised controlled trials that an initial strategy of coronary artery bypass surgery is associated, in the long term, with reduced mortality rates in patients with significant left main-stem stenosis, three vessel disease and proximal left anterior descending artery disease.2 However, it should be remembered that, on average, coronary artery bypass surgery prolongs life by only 4.26 months.2 Secondly, the six month postoperative period analysed here accentuates mortality risk associated with the procedure itself; for people who would benefit prognostically from surgery, the total risk faced is the sum of the risk while waiting plus the postoperative ...
BACKGROUND: External stents inhibit saphenous vein graft (SVG) intimal hyperplasia in animal studies. We investigated whether external stenting inhibits SVG diffuse intimal hyperplasia 1 year after coronary artery bypass graft surgery. METHODS: Thirty patients with multivessel disease undergoing coronary artery bypass graft surgery were enrolled. In addition to an internal mammary artery graft, each patient received one external stent to a single SVG randomly allocated to either the right or left coronary territories; and one or more nonstented SVG served as the control. Graft patency was confirmed at the end of surgery in all patients. The primary endpoint was SVG intimal hyperplasia (mean area) assessed by intravascular ultrasonography at 1 year. Secondary endpoints were SVG failure, ectasia (|50% initial diameter), and overall uniformity as judged by Fitzgibbon classification. RESULTS: One-year follow-up angiography was completed in 29 patients (96.6%). All internal mammary artery grafts were patent.
This 3D medical animation shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.

Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery. A normal coronary artery transports blood to and from the heart muscle itself, not through the main circulatory system. There are two main approaches. In one, the left internal thoracic artery (internal mammary artery) is diverted to the left anterior descending branch of the left coronary artery. In the other, a great saphenous vein is removed from a leg; one end is attached to the aorta or one of its major branches, and the other end is attached to the obstructed artery immediately after the obstruction to restore blood flow. CABG is performed to relieve angina unsatisfactorily controlled by maximum tolerated anti-ischemic medication, prevent or relieve left ventricular dysfunction, and/or reduce the risk of death. CABG does not prevent myocardial ...
Objective: To evaluate our experience with the radial artery in coronary artery bypass grafting. Methods: We studied 156 consecutive patients who had a single radial artery as coronary grafts. All patients underwent a modified Aliens test. Radial artery were harvested by no touch technique. Results: An average of 3.3 grafts perpatient were performed. Operative mortality occurred in 1 (0.6%) patients, no stroke, deep sternal infection and fingertip ischemia. Reoperation for hemorrhage in 2 (1.3%), and myocardial ischemia in 1 (0.6%). Conclusion: Good early clinical results can be achieved by using the radial artery in coronary artery bypass grafting.
OBJECTIVES: There is still little evidence to boldport routine dual antiplatelet therapy (DAPT) with P2Y12 antagonists following coronary artery bypass grafting (CABG). The Arterial Revascularization Trial (ART) was designed to compare 10-year survival after bilateral versus single internal thoracic artery grafting. We aimed to get insights into the effect of DAPT (with clopidogrel) following CABG on 1-year outcomes by performing a post hoc ART analysis. METHODS: Among patients enrolled in the ART (n = 3102), 609 (21%) and 2308 (79%) were discharged on DAPT or aspirin alone, respectively. The primary end-point was the incidence of major adverse cerebrovascular and cardiac events (MACCE) at 1 year including cardiac death, myocardial infarction, cerebrovascular accident and reintervention; safety end-point was bleeding requiring hospitalization. Propensity score (PS) matching was used to create comparable groups. RESULTS: Among 609 PS-matched pairs, MACCE occurred in 34 (5.6%) and 34 (5.6%) in the DAPT
Background and objective: Myocardial ischaemia and infarction are major complications immediately after coronary artery bypass grafting. They may be due to incomplete surgical revascularization, perioperative anaesthetic management or vasospasm of arterial grafts, e.g. the internal mammary artery. Infusions of nifedipine or milrinone have been advocated to prevent spasm of the mammary artery. The study compared the incidence of myocardial ischaemia after continuous infusion of either nifedipine (0.2 µg kg−1 min−1) or milrinone (0.375 µg kg−1 min−1) in patients with compromised left ventricular function scheduled for elective coronary artery bypass graft.. Methods: After Institutional Review Board approval, this double-blinded randomized clinical study enrolled 30 adult patients with compromised left ventricular function (ejection fraction ,0.4) scheduled for elective coronary artery bypass grafting after written informed consent had been obtained. Ischaemia was detected by Holter ...

Objective. To investigate oxidative stress and myocardial injury at different stages of coronary artery bypass grafting (CABG). Design. Twenty patients underwent CABG with use of cardiopulmonary bypass (CPB) and with intermittent sampling of plasma and urine. Main markers were: 8-iso-PGF(2 alpha) (oxidative stress); troponin T (myocardial injury); and 15-keto-dihydro-PGF2 alpha and hsCRP (inflammation). Results. Plasma 8-iso-PGF2 alpha increased after start of surgery, but there was no further rise during CPB or after aortic cross-clamp release and no significant myocardial arterio-venous differences. An increase in troponin T was seen early after the operation, but no relationship was established between 8-iso-PGF2 alpha and troponin T. 8-iso-PGF2 alpha levels were elevated by preoperative withdrawal of acetylsalicylic acid (ASA) but reduced by intraoperative use of heparin. 15-keto-dihydro-PGF2 alpha was elevated during operation and hsCRP following operation. Conclusions. In the present study ...
Background: Anxiety and depression are the most common complications after coronary artery bypass surgery. Although patients may gain some physical and psychological benefit from cardiac rehabilitation after cardiac surgery, but some individuals and social aspects may change the cardiac rehabilitation procedure. Aim: The aim of this study was to determine the effect of short-term cardiac rehabilitation on anxiety and depression in patients after coronary artery bypass surgery. Methods: In this quasi-experimental pretest - post test design study, all patients undergoing coronary artery bypass surgery in Razavi hospital in Mashhad (1392) were participated and for sampling, 70 patients allocated into experimental and control groups by non-randomly convenient method.

For over a decade there has been accumulating evidence that the use of more than a single arterial graft during coronary artery bypass grafting can improve clinical outcomes. However the vast majority of patients in most developed countries still only receive a single arterial conduit even in the presence of multivessel coronary artery disease. This review summarizes the current evidence for the use of a second internal mammary artery and/or radial artery graft. While in comparison to vein grafts the superior patency of internal mammary artery grafts is well established, there now exists strong and consistent evidence of the superior patency of radial arteries over the longer term. Likewise, there is a rapidly growing body of evidence that the superior patency of both these arteries in comparison to vein grafts translates into improved clinical outcomes.
Introduction: Cardiovascular diseases (CVDs) have become the most important cause of non - communicable disease deaths.According to WHO statistics, cardiovascular diseases are the most common cause of deaths in the world.In every open heart surgery, there is the risk of complications specific to the disease and surgery being performed, in addition to the general risks related to surgery and anesthesia. Both CABG & valvular surgeries are performed to improve functional capability and quality of life. Aim: To assess the physical outcome and its determinants of patients undergoing Coronary artery bypass graft and valvular surgeries. Methods: In this prospective observational study, 40 patients who underwent coronary artery bypass graft or valvular surgery were selected through consecutive sampling method from August 2018 to February 2018. The tools used for data collection were numerical rating scale to assess postoperative pain, performance check list for using incentive spirometry and subject ...

The objective of this study was to assess the impact of CAGB surgery-induced alterations in ANG1, ANG2 and TIE2 levels on post-surgical SIRS and to evaluate potential mechanisms inducing capillary leakage. Our results indicate that CABG induced profound changes in the ANG2/ANG1 balance with loss of the barrier-protective ANG1 and an increase in the barrier-disruptive ANG2 contents in the patients serum. This imbalance was observed in adult patients with systemic pro-inflammatory response characterized by elevated IL-6 levels. The molecular changes correlated with clinical surrogate parameters of an impaired endothelial barrier function, such as fluid balance, application of vasoconstrictors, and prolonged ventilation.. In healthy individuals, constitutive expression of ANG1 results in much higher serum concentrations than ANG2, which is mainly secreted upon endothelial stimulation; therefore, an increased ratio between ANG2 and ANG1 (in healthy adults a numerical value below 1) serves as marker ...

A 50-year-old man who had coronary artery bypass grafting (LITA-LAD, RA-RCA, SVG-OM-PL) 6 years previously was admitted with acute dissection of the aorta (DeBakey type T). Preoperative computed tomography showed that all coronary bypass grafts were patent. We replaced the graft of the ascending aorta and reconstructed the coronary artery bypass by re-sternotomy, circulatory arrest (rectal temperature: 23.6 ), retrograde cerebral perfusion, and intermittent retrograde cardioplegia. Because a radial artery (RA) graft and a saphenous vein graft (SVG) each had intact orifices, we detached them together and attached the grafts back to the aortic graft wall. He was weaned successfully from cardiopulmonary bypass without difficulty and postoperative transthoracic echocardiography (TTE) showed good left ventricle (LV) function. Postoperative multidetector-row computed tomography (MDCT) showed that the RA graft and SVG were patent. By performing circulatory arrest and intermittent retrograde ...
Coronary artery bypass surgery.: Coronary artery bypass surgery has taken many strides to become the effective intervention it is today. Although it has been th
More than 50% of aortocoronary saphenous vein grafts are occluded 10 years after surgery. Intimal hyperplasia is the initial critical step in the progression toward occlusion. Internal mammary veins, which are physiologically prone to less hydrostatic pressure, may undergo an accelerated progression to intimal hyperplasia and thus be suitable for investigation of the mechanisms of aortocoronary vein graft disease. Six minipigs underwent aortocoronary bypass grafting using standard cardiopulmonary bypass and cardioplegic arrest. Mammary vein were grafted in a reversed manner from ascending aorta to left anterior descending coronary artery (LAD). The proximal LAD was ligated, rendering the anterior left ventricle vein graft-dependent. Minipigs were killed after 4 weeks, and vein grafts were harvested. Histological and immunohistological investigation were performed with respect to morphometric analysis, endothelial damage/dysfunction (v-Willebrand-factor (vWF)), smooth muscle cells (α-smooth actin) and
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 ...
Aim: The aim of this study was to identify echocardiographic LV systolic and diastolic measurements that predict clinical events post-coronary artery bypass graft (CABG) surgery. Methods: We collected data from 27 patients (age 70 +/- 7 years) who underwent elective CABG, before and within 6 weeks after surgery. LV systolic function was assessed by conventional echocardiographic parameters. A number of LV filling measurements were also made, which included total isovolumic time (t-IVT), Tei index, and restrictive filling pattern. Postoperative cardiac events were death or hospitalization for chest pain, breathlessness, or arrhythmia. Results: Patients follow-up period was 17 +/- 10 months. Of the 27 patients (age 70 +/- 7 years, 22 male), 10 had postoperative cardiac events. LV ejection fraction (EF) and fractional shortening (FS) were lower (P = 0.01, and P = 0.007, respectively), t-IVT longer (P , 0.001), and Tei index was higher (P , 0.001) preoperatively in patients with events compared to ...

Objective: The The Arterial Revascularization Therapies Study (ARTS)-II trial found no differences in survival or overall adverse events between sirolimus-eluting stents (SES) and the surgical arm of ARTS-I. Nevertheless, existing data suggest that patients with disease of the proximal left anterior descending artery (LAD) may derive particular benefit from coronary artery bypass grafting (CABG). We therefore analysed the clinical outcome of patients in ARTS-I and ARTS-II with proximal LAD involvement.. Design: Multicentre observational study.. Setting: Forty-five European academic hospitals.. Patients: Patients with multivessel coronary artery disease.. Interventions: Patients in ARTS-II with proximal LAD disease treated with SES (289/607, 48%) were compared with 187/600 (31%) bare metal stent patients (ARTS-I BMS) and 206/605 (34%) surgical patients (ARTS-I CABG) with proximal LAD involvement from ARTS-I..

The impact of the relief of anginal symptoms, the reduction in the incidence of acute myocardial infarction, and the improvement in survival in some subgroups of patients with impaired ventricular function support the use of coronary artery bypass surgery (CABG) as an effective treatment for ischemic heart disease 1,2. The observation of the development of intimal hyperplasia, atherosclerosis, and the occurrence of thrombosis and occlusion in the grafts, mainly the venous 3, motivated a progressive increase in the use of arterial grafts, in an attempt to decrease the indices of occlusion of venous grafts, which ranged from 5% to 15% in the first month, and 15% to 25% in the first year, and reached up to 50% in the first 10 years 4-6. Therefore, based on the Coronary Artery Surgery Study 7, which was carried out in the 1970s and used the left internal thoracic artery (LITA) as a graft for the anterior interventricular branch (AIVB) 8 in up to 20% of the patients, the arterial graft became ...
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 ...

OBJECTIVES. Improvement in quality of life (QoL) and survival benefit are the primary objectives of coronary artery bypass graft (CABG) surgery. The profile of patients undergoing isolated CABG has altered towards higher age with more preoperative comorbidities. Thus, the importance of QoL over the quantity of life among elderly patients is getting more emphasized. In this study, our main goal was to evaluate the long-term changes in QoL, overall performance status and symptomatic status after the CABG.. METHODS. Comprehensive data of 508 patients who underwent isolated CABG in a single institution were prospectively collected. The RAND-36 Health Survey (RAND-36) was used as an indicator of QoL. Karnofsky dependency category was used to evaluate overall performance status, and symptomatic status was assessed using New York Heart Association (NYHA) class. All assessment were made preoperatively and repeated 1 year and 12 years later. The follow-up of the study cohort was complete in 95 and 84% of ...
The aim of this study is to evaluate the relationship between Body Mass Index (BMI) and the outcomes of isolated CABG (Coronary Artery Bypass Graft) performed in Shahid Madani Hospital of Khorramabad, Iran. Data was retrospectively collected from the medical records retrieved from the hospital records office. All patients who had undergone isolated CABG under cardiopulmonary bypass in the Cardiothoracic Unit from 2007 till 2013 were identified and their demographic and clinical data were collected. Clinical data included BMI, ejection fraction (EF), history of COPD, MI, CVA, diabetes mellitus, hyperlipidemia, hypertension and the main outcomes included pulmonary complications, renal complications, transfusion, duration of ventilation, reoperation, intensive care unit stay, hospital stay and death. Patients were divided into six groups according to the BMI as follows: group 1: (BMI | 18.5), group 2: (18.5 ≤ BMI | 25), group 3: (25 ≤ BMI | 30), group 4: (30 ≤ BMI | 35), group 5: (35 ≤ BMI | 40),

BACKGROUND: Current risk models predict in-hospital mortality after either coronary artery bypass graft surgery or percutaneous coronary interventions separately, yet the overlap suggests that the same variables can define the risks of alternative coronary reperfusion therapies. Our goal was to seek a preprocedure risk model that can predict in-hospital mortality after either percutaneous coronary intervention or coronary artery bypass graft surgery. METHODS AND RESULTS: We tested the ability of the recently validated, integer-based Mayo Clinic Risk Score (MCRS) for percutaneous coronary intervention, which is based solely on preprocedure variables (age, creatinine, ejection fraction, myocardial infarction , or = 24 hours, shock, congestive heart failure, and peripheral vascular disease), to predict in-hospital mortality among 370,793 patients in the Society of Thoracic Surgeons database undergoing isolated coronary artery bypass graft surgery from 2004 to 2006 ...
Coronary artery bypass graft surgery (CABG) is a major advance in the care of patients with coronary disease (1,2). Over 500,000 patients now undergo CABG in the United States each year, making it the most frequent major operation performed (2). Although CABG improves symptoms and decreases mortality in certain subsets, coronary atherosclerosis continues to progress in native coronary arteries. In fact, atherosclerosis of native coronary and saphenous vein grafts (SVG) is accelerated, and low-density lipoprotein (LDL) cholesterol is an important causative factor (3). The accelerated atherosclerosis in these patients results in recurrent angina in 15% and ischemic events in 10% at 5 years after CABG (1).. On the basis of the findings of several recent studies, including the TNT (Treating to New Targets) study, aggressive lowering of LDL-cholesterol to 70 to 80 mg/dl or lower in coronary patients decreases major cardiovascular events (4-6). However, the role of aggressive lipid-lowering in ...

Coronary Artery Bypass Graft surgeries are performed to restore blood flow to the heart of a patient with Coronary Artery Disease, which is a leading causes of death in the United States. After receiving a CABG or corrective procedure for revascularization, patients often receive cardiac rehabilitation and physical therapy to reduce postoperative complications and optimize their return to daily functional activities. Patient is a 78 year-old male with a history of severe CAD with nine prior stent procedures and one angioplasty who received a CABG surgery to bypass 2 arteries on his heart, his LAD and RCA. The patient was independent with daily activities and mobility prior to the surgery. Patient completed 5 cardiac rehab sessions, 3 of which PT was present for while in the hospital, first seen in the Intensive Care Unit until he was transferred to the Telemetry floor. The patient had improved outcomes in the AM-PAC and 2MWT outcome measures as well as decrease in assistance with ambulation and

BACKGROUND: We previously reported that there was no significant difference at 30 days or at 1 year in the rate of the composite outcome of death, stroke, myocardial infarction, or renal failure between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report the results at 5 years (the end of the trial). METHODS: A total of 4752 patients (from 19 countries) who had coronary artery disease were randomly assigned to undergo off-pump or on-pump CABG. For this report, we analyzed a composite outcome of death, stroke, myocardial infarction, renal failure, or repeat coronary revascularization (either CABG or percutaneous coronary intervention). The mean follow-up period was 4.8 years. RESULTS: There were no significant differences between the off-pump group and the on-pump group in the rate of the composite outcome (23.1% and 23.6%, respectively; hazard ratio
There is insufficient knowledge about secondary prevention after coronary artery bypass grafting (CABG). Most of it is gathered from patients suffering from myocardial infarction and angina pectoris, only a minority of whom have undergone CABG. Whereas it seems clear that these patients should give up smoking and reduce low‐density lipoprotein (LDL) cholesterol, there is uncertainty about the optimal antiplatelet regimen and antithrombotic treatment. There are some data indicating the benefit of behaviour modification. There is room for improvement and more knowledge when it comes to secondary prevention after CABG.. ...
OBJECTIVE: To describe mortality, mode of death, risk indicators for death and symptoms of angina pectoris among survivors during 5 years after coronary artery bypass grafting (CABG) among patients with and without a history of diabetes mellitus. METHODS: All patients in western Sweden who underwent CABG without concomitant valve surgery and who had no previous CABG between June 1988 and June 1991 were entered prospectively in this study. After 5 years, information on deaths that had occurred was obtained for the analysis. RESULTS: In all, 1998 patients were included in the analysis; 242 (12%) had a history of diabetes. Among the non-diabetic patients, 5-year mortality was 12.5%; the corresponding relative risk for diabetic patients was 2.1 (95% confidence interval 1.6 to 2.9). A history of diabetes was an independent risk indicator of death; there was no significant interaction between any other risk indicator and diabetes. Independent risk indicators for death among diabetic patients were: ...

At the present time staged carotid reconstruction several days before elective coronary artery bypass surgery seems to be the safest and most logical approach for patients with neurological symptoms, stable cardiac symptoms, and acceptable coronary anatomy. Combined procedures may well be necessary for those who have active neurological symptoms or bilateral carotid lesions in conjunction with diffuse or unstable coronary artery disease, but the incidence of neurological complications at the time of simultaneous operations could exceed the stroke risk for either carotid endarterectomy or coronary bypass alone. The asymptomatic patient with unilateral carotid stenosis who presents for coronary artery bypass might be best managed by myocardial revascularization followed by medical or surgical management of the carotid disease. In order to obtain optimal long-term results, both coronary disease and associated carotid disease require appropriate evaluation and medical and surgical management. ...
An 86-year-old woman was transferred to our hospital because of chest pain and left incomplete paralysis. CT-scan revealed a dissecting aortic aneurysm (DeBakey type2) 6cm in diameter. Coronary angiography and aortography were perfomed to assess the coronary artery disease and ASO, they showed occluded LAD, 90% stenosis of CX and occluded left external iliac artery. We planned a 1-stage operation. Coronary artery bypass grafting with the beating heart was carried out prior to replacement of the ascending aorta. Then we performed femoro-femoro bypass. The postoperative course was uneventful and the patient was discharged 23 days after the operation ...
After the surgery you may be taken to the recovery room before being taken to the intensive care unit (ICU) to be closely monitored. Alternatively, you may be taken directly to the ICU from the operating room. You will be connected to monitors that will constantly display your electrocardiogram (ECG or EKG) tracing, blood pressure, other pressure readings, breathing rate, and your oxygen level. Coronary artery bypass surgery requires an in-hospital stay of several days or longer.. You will most likely have a tube in your throat so that breathing can be assisted with a ventilator (breathing machine) until you are stable enough to breathe on your own. As you continue to wake up from the anesthesia and start to breathe on your own, the breathing machine will be adjusted to allow you to take over more of the breathing. When you are awake enough to breathe completely on your own and you are able to cough, the breathing tube will be removed. The stomach tube will also be removed at this time.. After ...

PURPOSE: Ischaemic myocardial dysfunction shows different time courses of functional recovery according to the pathophysiological characteristics of the dysfunction. In this study, we investigated the time course of functional recovery according to the preoperative reversibility of perfusion impairment on myocardial single-photon emission computed tomography (SPECT) after revascularisation surgery. METHODS: Forty-eight patients (42 men and 6 women; mean age 59+/-9 years) who underwent revascularisation surgery were included in the study. 201Tl rest/dipyridamole stress (99m)Tc-sestamibi gated SPECT was performed 10+/-8 days before (preoperative), 105+/-13 days after (early follow-up) and 497+/-66 days after (late follow-up) surgery. Using a 20-segment model, segmental perfusion and thickening were quantified with automatic software. As an indicator of the reversibility of perfusion impairment, a reversibility score (RevS) was defined as a measure of rest minus stress perfusion values. Segmental ...

Background: The elderly population (age ,70 years) incurs greater mortality and morbidity following CABG. OPCAB may mitigate these otucomes. A retrospective analysis of the results of OPCAB in this population was performed. Methods: We reviewed the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) database for elderly patients (n=12697) undergoing isolated CABG surgery and compared the ONCAB (n=11676) with OPCAB (n=1021) technique. Preoperative and intraoperative risk factors, and postoperative outcomes were analysed. Survival analyses was performed after cross-matching the database with the national death registry to identify long-term mortality. Results: High-risk patients were more prevalent in the ONCAB group (p,0.05). OPCAB patients received fewer distal anastomoses than ONCAB patients (2.4±1.1 vs 3.3±1.0, p,0.001). Thirty-day mortality and stroke rates between OPCAB and ONCAB were not significantly different (2% vs 2.5% and 1.1% vs 1.8%, respectively). There ...
When arteries that feed oxygen to the heart are blocked, the heart muscle is at risk for damage - called a heart attack - and even death. In an operation known as coronary artery bypass grafting (CABG), an artery or vein from another part of the body is used to reroute blood flow around the blockage. Surgeons use chest wall arteries (known as internal mammary arteries) and segments of the patients own veins to construct new pathways for blood and oxygen to reach the heart.
Heart failure is a leading cause of death in Canada. As part of the ongoing IMPACT-CABG clinical trial to treat advanced heart failure, physicians at the Peter Munk Cardiac Centre performed the first cardiac stem cell transplant in Ontario using stem cells derived from the patients own bone marrow, isolated completely within the operating room, and implanted into the heart at the time of coronary bypass surgery. Researchers hope that stem cell therapy may be developed into a novel treatment for the 50,000 Canadians diagnosed each year with advanced heart failure. The first patient to receive this type of stem cell therapy, James Culross, a 67-year-old man from Etobicoke, will be discharged this week after 2.83 million stem cells were injected into seven sites where his heart had been damaged by a heart attack in November 2011. The stem cells were injected following coronary artery bypass graft (CABG) surgery, by a multi-disciplinary team led by Dr. Terrence Yau, Cardiac Surgeon and Director of ...

You may not always be able to choose between having a coronary angioplasty or a coronary artery bypass graft, 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 coronary artery bypass graft. 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 treatment has fallen in recent years because of the use of special drug-eluting stents that reduce the risk of the artery narrowing again. See how a coronary angioplasty is performed for more information about these.. A coronary artery bypass graft has a longer recovery time than coronary angioplasty and a higher risk of complications. However, only one person in 10 who has a coronary artery bypass graft needs further ...

BACKGROUND: Standard coronary artery bypass graft surgery uses a single internal mammary artery and supplemental vein or radial artery grafts. Several observational studies have suggested a survival benefit with two internal mammary artery grafts compared to a single internal mammary artery graft, but this has not been tested in a randomised trial. The Arterial Revascularisation Trial is a Medical Research Council and British Heart Foundation funded, multi-centre international trial comparing single internal mammary artery grafting versus bilateral internal mammary artery grafting. METHODS/DESIGN: Twenty centres in the UK, Australia, Poland and Brazil are planning to randomise 3000 coronary artery bypass graft surgery patients to single or bilateral internal mammary artery grafting. Supplemental grafts may be either saphenous vein or radial artery. Coronary artery bypass grafting can be performed as an on-pump or off-pump procedure. The primary outcome is survival at 10 years and secondary end-points
Background: Coronary artery disease is sometimes associated with chronic conduction block. Our aim is to correlate between chronic conduction block and coronary artery disease. We performed ECG and coronary angiography of all patients who were admitted for permanent pacemaker implantation to find correlation between them. Methods: Coronary angiography was performed in all 160 patients of chronic conduction block during twenty four months of study period who were admitted for pacemaker implantation. We compared the coronary artery disease in different types of conduction block. Results: Among the study population 35(22%) patients are of single vessel coronary artery disease (CAD),13 (8%) patients had double vessel coronary artery disease, 6 (4%) patients had triple vessel coronary artery disease, 2 (1%) patients had left main disease and 104 (65%) patients had normal or insignificant coronary anatomy. Conclusion: Coronary artery disease is quite common in chronic conduction disorder. So there ...
