Coronary-pulmonary arterial fistula in a neonate with pulmonary atresia-ventricular septal defect and single coronary artery

Abstract

In cases of pulmonary atresia with ventricular septal defect (PA-VSD), coronary-pulmonary arterial fistula (CPAF) as the main source of pulmonary blood supply is extremely rare. These fistulae may arise from the left coronary artery, right coronary artery, or a single coronary artery. Fistulae from a single coronary artery are unusual. We are reporting a case of PA-VSD with single coronary artery and CPAF as the main source of pulmonary supply in addition to two major aortopulmonary collateral arteries (MAPCAS). Successful surgical correction with VSD closure and right ventricle (RV) to the pulmonary artery (PA) conduit was made.
