Coronary Artery Aneurysm: Its Evaluation in a 27-Year-Old Female Patient, Prognosis, and Suggested Treatment Strategies

Abstract

Coronary artery aneurysm (CAA) is characterized by a localized dilation of one or more of the coronary arteries with multiple etiologies, including congenital, acquired, or connected to auto-inflammatory diseases with multiple shapes and classifications. It is usually diagnosed incidentally during coronary imaging and can have variable clinical outcomes, ranging from asymptomatic to sudden cardiac death with a generally poor prognosis. Management of this condition faces a clinical dilemma due to the lack of clear guidelines or randomized trials. Treatment should be individualized based on symptoms, shape, and comorbidities. Herein, we present the case report of a 27-year-old female patient with no prior medical conditions. However, she presented with palpitations, and a compressive mass located over the right atrium was identified in the patient. After undergoing cardiac catheterization and coronary scanning, a giant aneurysm of the sinoatrial branch was detected with an aneurysmal left main that was retrieved surgically with good recovery and postoperative course.
