Experience of emergency coronary artery bypass grafting surgery and operative transluminal coronary angioplasty.
Our experience of performing emergency coronary artery bypass surgery in 9 patients with acute myocardial infarction (AMI) and of intraoperative transluminal coronary angioplasty (OTCA) during bypass surgery in another 28 patients was reviewed. Data were evaluated in conjunction with the recent application of intracoronary thrombolytic therapy and percutaneous transluminal coronary angioplasty. In 4 of the 9 cases where the emergency coronary artery bypass grafting (CABG) was performed within 2 hours after the onset of AMI, no new Q waves appeared in electrocardiograms (3 cases), and remarkable improvement of left ventriculographic findings was noted when pre- and postoperative ventriculograms were compared in 2 of these 4 cases. Intraoperative transluminal coronary angioplasty was successful in only 51.6% of the cases when evaluated at the post bypass period and this was less successful than our experience with PTCA. The low success rate was considered to be due to the greater amount of intimal fibrosis in the more distal portion, where the OTCA is performed, than is found in the proximal portion of the coronary arteries.
