We describe a surgical case of coronary-coronary bypass grafting using the saphenous vein for revascularization of the right coronary artery during concomitant graft replacement of the ascending aorta. This technique of coronary revascularization can be used as an alternative to avert the need for a prosthetic graft to coronary artery bypass grafting in cases with potential problems of anastomo...

BACKGROUND The left internal mammary artery (LIMA) to left anterior descending coronary artery (LAD) graft is the most important graft in coronary artery bypass graft surgery.1 The length of the LIMA is fixed and situations may arise when this is inadequate.2 This may not be apparent during the cardiopulmonary bypass until after the anastomosis has been performed and the lungs re-expanded. We d...

Progressive late obstruction of an aorto-coronary venous bypass graft is reported in a 44-year-old man who died of bi-ventricular failure 114 days after surgery. The first portion of the vein graft had a residual lumen of one mm. Histology showed marked intimal fibrosis. Mechanism for this occlusion and fibrosis is unclear. This representsc the first documented case of late obstruction of an ao...

OBJECTIVES The aim of this study was to evaluate the intraoperative fluorescence imaging (IFI) system in the real-time assessment of graft patency during off-pump coronary artery bypass graft. BACKGROUND Intraoperative fluorescence imaging is an intraoperative angiography-like imaging modality using fluorescent indocyanine green excited with laser light. Recently, assessment of graft patency ...

OBJECTIVES Patients with coronary artery disease and left ventricular dysfunction have high mortality when kept in clinical treatment. Coronary artery bypass grafting can improve survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study is to compare patients with left ventricular ejection fract...

Non-Newtonian fluid flow in a stenosed coronary bypass is investigated numerically using the Carreau-Yasuda model for the shear thinning behavior of the blood. End-to-side coronary bypass anastomosis is considered in a simplified model geometry where the host coronary artery has a 75% severity stenosis. Different locations of the bypass graft to the stenosis and different flow rates in the graf...

BACKGROUND Saphenous vein graft disease remains a major limitation of coronary artery bypass graft surgery. The process of saphenous vein intimal hyperplasia begins just days after surgical revascularization, setting the stage for graft atherosclerotic disease and its sequalae. Clopidogrel improves outcomes in patients with atherosclerotic disease, and is effective at reducing intimal hyperplas...

this article describes coronary artery bypass grafting by avlliath jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. the aim of coronary artery bypass grafting is to release pain, prevention of myocardial inf...
