Abstract
This anomaly forms due to a lack or a separation between the aortic wall media and the aortic valve’s annulus fibrosus. The delivery cardiac chamber of a right aortic sinus fistula is typically the right ventricle. However, infrequently, when there is noncoronary cusp involvement, the right atrium becomes the drainage location. The left aortic sinus is rarely involved. Related abnormalities consist of ventricular septal defect, bicuspid aortic valve, and coarctation of the aorta [1, 2].
