Giant Coronary Artery Aneurysm Complicated With Aortic Regurgitation

Abstract

We present a rare case of a patient diagnosed with aortic insufficiency grade III and a giant coronary artery aneurysm with a maximum diameter of 12 cm. Surgical intervention revealed an incompetent bicuspid aortic valve and a huge thrombosed aneurysm, which communicated with the aorta through the left coronary ostium. In addition to direct closure of the ostium, a saphenous vein was anastomosed to the left anterior descending artery, and the aortic valve was successfully replaced with a mechanical valve.
