7-day-old girl with complex cardiac malformation including right isomerism, transposition of the great arteries and pulmonary atresia with non-confluent pulmonary arteries. 3D volume rendered CE-MRA image from posterior (with partial removal of the descending aorta) shows blood supply to the right lung via a PDA (black arrow) originating from the undersurface of the aortic arch, anastomosing with the native pulmonary artery at the hilum and with a distal stenosis > 50%. Blood supply to the left lung via a PDA (white arrow) originating from the innominate artery and anastomosing with the native pulmonary artery at the hilum.
