Giant Right Coronary Artery Aneurysm Associated with a Fistula Draining into the Superior Vena Cava

Abstract

Giant coronary artery aneurysm associated with a coronary–cameral fistula is an uncommon condition. Such aneurysms are usually associated with other cardiac diseases, such as coronary atherosclerosis, and therefore might augment myocardial ischemia in adults. The main indications for surgical intervention are severe coexisting coronary artery disease, evidence of embolization, and aneurysmal enlargement or rupture. We describe a large right coronary artery aneurysm and a coronary–cameral fistula that drained into the superior vena cava. The surgical repair was successful.
