Coronary Artery Bypass Grafting for Coronary Aneurysms Causing Acute Myocardial Infarction;Report of a Case

Coronary aneurysms are relatively rare. However, myocardial infarction associated with thrombus formation in the aneurysm and rupture of the aneurysm are clinical problems. There are no specific guidelines for the treatment of coronary aneurysms. Here, we report a case of a 47-year-old female with acute myocardial infarction. She had a history of collagen disease, which was suspected to be Kawasaki disease. She underwent thrombus aspiration supported by intra-aortic balloon pumping( IABP) because of acute thrombosis of coronary aneurysms, followed by coronary artery bypass grafting on 2 stages. The operative course was uneventful.
