[Surgical Treatment of Giant Coronary Artery Aneurysm Presented as Acute Coronary Syndrome]

Abstract

Coronary artery aneurysm is rare disease, usually asymptomatic and is often found by chance by echocardiography, computed tomography(CT) and coronary angiography. However, its rupture or thrombotic obstruction to the periphery of the coronary artery leads to cardiac tamponade, angina pectoris, or myocardial infarction. We describe 2 cases of giant coronary artery aneurysm presented as acute coronary syndrome. Surgical resection of the aneurysm and coronary artery bypass grafting were successfully carried out under cardiopulmonary bypass. Postoperative courses of both cases were uneventful, and the patients were free of symptoms.
