Abstract

Pulmonary atresia with ventricular septal defect is a complex congenital cardiac anomaly. The blood is supplied to the lungs through a patent ductus arteriosus, a major aortopulmonary collateral artery, or in very rare cases from a coronary artery–pulmonary artery fistula. We present two cases with coronary artery–pulmonary artery fistula which underwent surgical intervention. In our first patient, the main pulmonary artery was supplied from the left main coronary artery. In the second patient, the right pulmonary artery originated from the left main coronary artery and continued to the right lung posteriorly to the aorta, while the left pulmonary artery originated from the patent ductus arteriosus. The difference in our cases is that the coronary artery pulmonary artery fistulas behave like major aortopulmonary collateral arteries originating from the coronary arteries. These fistulas were the main source of pulmonary blood flow.
