Aortic-to-Right Ventricle Shunting for Rare Cardiovascular Conditions.

Pulmonary atresia with hypoplastic right ventricle and ventricular septal defect with right ventricle-dependent coronary circulation are very rare congenital heart anomalies. This report describes the case of a patient in whom aortic-right ventricle shunting was surgically established with a satisfactory postoperative course. Aortic-right ventricle shunting can enhance oxygenation of the sinusoidal communication and reduce the incidence of myocardial ischemia without influencing the left ventricular volume load through the ventricular septal defect despite preservation of the septal defect.
