title: Ruptured right coronary artery aneurysm presenting as a myocardial mass.
abstract: Rupture of a coronary artery aneurysm may result in a contained hematoma and an intramyocardial mass. We present a case of a contained coronary artery aneurysm rupture presenting as a mass in the right ventricle. The mass was suspected in a preoperative transthoracic echocardiogram and identified at the time of elective coronary artery bypass surgery. We discuss the pathophysiology, clinical presentation, diagnostic features, and management of this uncommon clinical presentation.
