Supracristal ventricular septal defect (SCVSD), a defect of the infundibular portion of the interventricular septum just below the right aortic cusp, occurs more frequently in Eastern Asian populations. SCVSD may be complicated by right sinus of Valsalva aneurysm (SoVA). We present the case of a 26-
