Aneurysms of the coronary arteries in the adult. Clincial and angiographic features.

One thousand coronary arteriograms were reviewed to determine the incidence, clinical presentation and angiographic features of aneurysms of the coronary artery (ACA) in adults with angina. Criteria for the angiographic diagnosis are described and the angiographic aspects are emphasized. The incidence of ACA was 1.1%. Saccular and fusiform aneurysms were seen. Single aneurysms were present in 7 patients. One patient had an abdominal aneurysm. Five patients underwent surgery; two had postoperative selective coronary angiography one year later and all five underwent follow-up left ventricular angiography. The most likely etiology of the aneurysms in this series is atherosclerosis.
