The usual sources of pulmonary blood flow in pulmonary atresia (PA) with(VSD) are patent ductus arteriosus and aortopulmonary collaterals. However, rarely fistulous collaterals may also arise from the coronary arteries which usually open into the main pulmonary trunk or branch pulmonary arteries. In such cases, selective coronary angiogram may be required for the demonstration of pulmonary arterial anatomy. A case of PA with VSD with failure to demonstrate pulmonary arteries on routine catheterization study (ventricular, aortic root, and descending aortic angiograms) is being presented here. A coronary artery-to-pulmonary artery fistula was suspected in view of dilated left main coronary artery, and pulmonary arteries were well demonstrated with selective coronary angiogram.
