title: Coronary artery collateral flow and its effect on myocardial perfusion in a patient with unilateral pulmonary artery atresia.
abstract: Unilateral pulmonary artery atresia is a rare congenital defect. The affected lung in unilateral pulmonary artery atresia usually receives its blood supply from many collateral vessels including the coronary artery. We report a case of an elderly woman with suspected anginal symptoms who had a coronary artery fistula functioning as a collateral vessel due to unilateral pulmonary artery atresia.
