Four patients are reported with obstruction of the proximal left main coronary artery that developed following prosthetic replacement of the aortic valve. Angina pectoris and ventricular arrhythmias were the presenting clinical manifestations. Anterior descending coronary artery bypass was used in 3 of the patients and vein patch angioplasty in the fourth. One patient died in the hospital. The 3 survivors achieved relief from angina and ventricular arrhythmias. One patient died from nephropathy 2 1/2 years later. Two patients remained asymptomatic 1 1/2 and 3 years later, respectively.

This review emphasizes the need for prompt coronary angiography in patients experiencing angina pectoris after aortic valve replacement, and it shows that coronary revascularization can be performed with satisfactory results.
