Described is a rare association in a patient with the heart in the left chest, namely pulmonary atresia with intact ventricular septum, fistulous coronary arterial connections, a right-sided aortic arch and an aorto-pulmonary collateral artery feeding one lung. The pulmonary arteries were non-confluent, with the right lung supplied by the right arterial duct originating from the under surface of the right-sided aortic arch, and the left lung supplied through the aorto-pulmonary collateral artery arising from the descending aorta. The surgical management is different in the setting of non-confluent pulmonary arteries.
