Right Coronary Artery From Right Sinus of Valsalva and Ventricular Tachycardia

Congenital coronary anomalies in which the coronary artery arises from the contralateral aortic sinus of Valsalva are associated with fatal arrhythmias and sudden death. The mechanism causing sudden death has been debated. We describe a case of an adolescent patient with right coronary artery arising leftward, but from the right sinus of Valsalva, with an acute-angle takeoff from the aorta and an intramural course, who presents with exercise-induced ventricular tachycardia.
