Abstract
Coronary artery aneurysm is a relatively rare disease, which may cause angina, myocardial infarction, or sudden death due to thrombosis, embolization or rupture. Coronary angiogram of a 84-year-old man revealed saccular coronary artery aneurysm at left anterior descending coronary artery and coronary artery severe stenosis. He underwent aneurysmorrhaphy of coronary artery aneurysm and coronary artery bypass grafting to left anterior descending coronary artery and diagonal branch without cardiopulmonary bypass. There were no complications and the postoperative course was uneventful. On postoperative coronary angiography, the aneurysm was disappeared and LITA was patent. Surgical approach should be determined by aneurysm size, presence of branching vessels, and degree of stenosis.
