Continuous improvement in multislice computed tomography technology has further enabled advances in coronary artery bypass graft imaging. Multidetector platforms and retrospective electrocardiography gating have enabled sensitivities and specificities in the 95% to 99% range while avoiding the morbidity associated with invasive catheter angiography. Identification of bypass graft stenoses and b...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

This meta-analysis evaluates the diagnostic accuracy of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) for bypass graft occlusion and stenosis detection compared with coronary angiography in post-coronary artery bypass graft patients. The indication for noninvasive imaging in post-coronary artery bypass graft patients with these techniques is discussed. Overall, M...

INTRODUCTION Coronary artery bypass graft is often the treatment of choice for patients who suffer from unstable angina. We do not know whether this condition adds morbidity in this scenario. OBJECTIVE To compare the outcomes of patients undergoing coronary artery bypass graft with unstable angina framework with patients who underwent coronary artery bypass graft showed no unstable angina. ...

OBJECTIVE To compare the early and late outcomes of off-pump coronary artery bypass grafting and coronary artery bypass graft + mitral valve repair in elderly patients with moderate chronic ischemic mitral regurgitation. METHODS One hundred and fifty elderly (age > 70 years) patients with moderate chronic ischemic mitral regurgitation who underwent off-pump coronary artery bypass grafting (n=...

The main purpose of the off-pump coronary artery bypass surgery is to reduce morbidity and mortality due cardiopulmonary bypass. However, even though many studies have shown that off-pump coronary artery bypass is feasible and provides hospital morbidity and mortality similar to the on-pump coronary artery bypass graft surgery, probably better in some aspects, its long-term results have been qu...

coronary artery disease is one of the leading causes of morbidity and mortality especially in the indusirialzcd societies. this retrospective study was carried out on 385 patients who were referred to shariati and jamaran hospitals from 1992 till 1997 and who underwent coronaty artery bypass grafting. the objective was to obtain a descriptive analysis of the important factors in this population...

A mechanical model of a branched coronary artery with a graft bypassing an 80% stenosis of one branch was used to study the reduction in coronary flow due to stenosis of the bypass graft. Flow Reynolds number and ratio of aortic pressure to dynamic pressure were matched to the living system. Changes in coronary flow were measured for a range of stenoses (0-100%) of bypass grafts with graft-to-c...
