We describe a 22-year-old woman with a history of unrepaired pulmonary atresia with ventricular septal defect. This woman was interesting in that her main pulmonary artery and right pulmonary artery arose from the left main coronary artery. She developed significant pulmonary hypertension in addition to isolation of the left pulmonary artery following ductal closure, subsequent to which the majority of her pulmonary blood flow was coronary dependent.
