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.
