Tetralogy of Fallot with pulmonary atresia associated with aortopulmonary window and major aortopulmonary collaterals

We report a patient with tetralogy of Fallot and pulmonary atresia in whom the predominant extracardiac supply of arterial blood was via an aortopulmonary window. Major aortopulmonary collateral arteries originating from the descending thoracic aorta provided an additional source of pulmonary blood flow. The patient underwent successful correction and the postoperative recovery was uneventful.
