title: Giant right coronary artery aneurysm complicated by acute myocardial infarction.
abstract: A coronary artery aneurysm is uncommon and frequently asymptomatic. This report presents a surgical case of a giant coronary artery aneurysm complicated by acute myocardial infarction. A 26-year-old man with sudden chest pain was referred to our hospital. Myocardial infarction was suspected, and emergency coronary angiography was performed. A giant coronary aneurysm was found in the mid-portion of the right coronary artery. The aneurysm, which was thrombosis-occluded, was successfully resected, and the right coronary artery was anastomosed in an end-to-end fashion. Although the strategy for treating a coronary artery aneurysm without myocardial ischemia remains controversial, surgical intervention should be considered in cases with a giant coronary artery aneurysm, even if asymptomatic, provided the surgical risk is low.
