Abstract
Between January 1987 and February 1988, 1,385 patients underwent percutaneous transluminal coronary angioplasty; 27 procedures were performed using prophylactic intraaortic balloon counterpulsation. Twenty-four patients had poor left ventricular function (EF < 40%), and coronary dilatation was performed in arteries opposite to an occluded myocardial necrosis related vessel. In three patients of advanced age with distal stenoses and normal left ventricular function a multivessel dilatation was performed. Primary success rate was achieved in all patients. There were no deaths, myocardial infarctions or emergency bypass operations in the hospiatilation period. During the follow-up (9 to 21 months) there were 2 deaths, 1 cardiac transplantation, and 6 restenosis with repeated dilatation. If revascularization is warranted, in high-risk patients, coronary angioplasty can be performed safely and successfully with protection by intraaortic balloon counterpulsation. However the long-term prognosis of these patients is complicated by the presence of other high-risk variables, such as advanced age or poor left ventricular function.
