Myocardial revascularization with the “horseshoe” graft

Pedicled omentum versus free omental graft for myocardial revascularization.

The most frequently used method for myocardial r e v e t i o n today is by direct arterial implantation into the heart in conjunction with use of a free omental graft. The question that is raised is whether the pedicled omentum might not be a greater s o m e of extra-cardiac blood than that supplied by the free omenlal graft. The intact omentnm has been used in the past, but never received clin...

Myocardial revascularization.

Myocardial consequences of coronary artery bypass graft surgery. The paradox of necrosis in areas of revascularization.

Myocardial infarction after coronary artery bypass graft (CABG) surgery has been described clinically in up to 30% of patients but there is little morphologic information about the character and pathogenesis of the myocardial injury. We studied myocardium in the distribution of bypassed and nonbypassed coronary arteries for the presence of contraction band necrosis as compared to coagulation ne...

Mitral valve replacement combined with myocardial revascularization

Of 300 consecutive patients undergoing primary operation for mitral valve replacement combined with coronary bypass grafting, 22 (7.3%) died in-hospital. Multivariate testing of preoperative and operative descriptors identified radiographic cardiac enlargement, preoperative paced rhythm or atrial fibrillation, 70% or more left main coronary obstruction, and serum bilirubin of more than 2 mg% as...

Myocardial laser revascularization.

Some patients with severe angina have coronary artery disease which is unsuitable for conventional forms of revascularization — coronary angioplasty/ stenting or coronary artery bypass surgery. These patients have usually undergone previous revascularization procedures and have disease which is diffuse and affects the distal part of the coronary circulation. Transmyocardial laser revascularizat...
