Abstract
Coronary artery aneurysms (CAAs) are uncommon but significant cardiovascular abnormalities characterized by an abnormal increase in vascular diameter. CAAs are classified based on their shape as either saccular or fusiform, and their causes can range from atherosclerosis, Kawasaki disease, to congenital and iatrogenic factors. CAAs often present asymptomatically, but when symptoms occur, they can include angina, myocardial infarction, or even sudden cardiac death due to intravascular thrombosis involving the CAA. Diagnosis is typically confirmed through coronary angiography, though CT and other imaging techniques can provide additional details. The management of CAAs is variable depending on their size, location, and the presence of symptoms or complications. Treatment options include medical therapy, percutaneous coronary intervention (PCI), or surgical approaches. In this paper, we describe the case report of a 79-year-old male who presented with palpitations and was diagnosed with a right coronary artery aneurysm, and a review of the literature is delineated, underscoring the importance of individualized treatment strategies for CAAs.
