[Giant Right Coronary Artery Aneurysm Complicated by Acute Myocardial Infarction:Report of a Case]

Abstract

The patient was a 45-year-old man who was transported by ambulance to a nearby clinic owing to sudden chest pain. He was diagnosed with myocardial infarction and giant coronary artery aneurysm by coronary arteriogram and underwent an emergency intervention for the myocardial infarction. The patient was referred to our hospital. Intraoperative findings showed the mass-like right coronary artery aneurysm at the anterior to the right atrium. The origin of the right coronary artery was ligated in addition to the fenestration and the proximal and distal regions of the coronary artery aneurysm. It has been reported that coronary artery aneurysms are usually asymptomatic and are often discovered by chance during screenings, such as echocardiography, computed tomography, and coronary arteriogram. Here, we report a surgical case of giant right coronary artery aneurysm complicated by acute myocardial infarction.
