Introduction
Giant coronary artery aneurysms (CAA) are a rare entity with a reported incidence of around 0.02%. They are typically discovered incidentally on angiography. Though they have no singular accepted definition, they tend to be understood as coronary aneurysms greater than 20mm and occur most often in the right coronary artery (RCA). Up to 50% of cases are attributed to atherosclerosis, followed by congenital causes (17-30%), and sequelae of Kawasaki disease (10%) with other rare etiologies including vasculitides and connective tissue disorders (1). Due to the rare and heterogeneous presentation of coronary artery aneurysm, there are no uniform guidelines with respect to medical or interventional management (2). In this report, we present a case of an incidentally found giant left anterior descending artery (LAD) aneurysm in a young healthy male, the imaging modalities used for diagnosis and operative planning, and the surgical approach utilized.
