Abstract
We report two cases of coronary artery aneurysm including one case of the left main coronary artery aneurysm. The coronary angiogram of one patient, a 68-year-old male, having anterior chest pain on exertion, revealed left anterior descending coronary artery (segment 6) aneurysm of 7 mm in diameter with 90% stenosis distal to the aneurysm and 75% stenosis in the right coronary artery (segment 2). The coronary angiogram of another patient, a 69-year-old female, having chest pain unrelated to exertion, revealed left main coronary artery aneurysm of 25 mm in diameter and delayed filling of contrast medium into the left anterior descending coronary artery. We decided to operate by the reason of not only significant coronary artery stenosis but risks of myocardial infarction due to embolization into distal coronary arteries and rupture of the aneurysm. We performed coronary artery bypass graftings using the great saphenous veins and closure of the coronary arteries running into and out the aneurysm under cardiopulmonary bypass. It is recommended that ligation of the coronary arteries connecting to the aneurysm or resection of the aneurysm followed by coronary artery bypass grafting is performed before developing myocardial infarction or rupture of aneurysm.
