A Rare Case of the Right Atrial Diverticulum Encroaching the Left Ventricle

Single diverticulum of the right atrium is a rare congenital malformation. We describe echocardiographic and computed tomography scan findings of a congenital right atrial diverticulum and its successful surgical resection in a 5-year-old boy. A review of available literature is also done discussing the possible etiology and management of this disease entity.
