Left main coronary artery disease: risk of angiography and surgery.

Abstract

Recent reports of high mortality associated with coronary arteriography’-3 and with coronary bypass surgery 1, 4, 5 in patients with severe obstruction of the left main coronary artery led us to review our experience with this lesion. Between September 1969 and January 1975, 27 patients with greater than 75% stenosis of the left main coronary artery were evaluated. These 27 patients form the basis of this report.
