title: Isolated Anomalous Origin of Left Pulmonary Artery From the Descending Aorta: An Embryologic Ambiguity.
abstract: Anomalous origin of a branch pulmonary artery from the aorta is a rare malformation, accounting for 0.12% of all congenital heart defects. Anomalous origin of the left pulmonary artery from the aorta (ALPA) constitutes a small proportion of these cases. ALPA has been reported to arise from the ascending aorta with various embryologic postulates. We report a case of isolated ALPA arising from the descending aorta in association with a patent ductus arteriosus, to emphasize its embryologic ambiguity.
