In 19 out of 28 cases of single ventricle with inverted infundibulum and 1-transposition of the great arteries the right coronary artery arose from the posterior aortic sinus, the right anterior aortic sinus being the noncoronary one. This coronary arterial pattern was described before only in association with d-transposition of the great arteries. We suggest that angiocardiographic demonstration of this coronary arterial pattern in association with an 1-positioned aorta favors the diagnosis of single ventricle.
