A Rare Anomaly of a Single Coronary Artery Arising From the Right Pulmonary Artery in a Neonate.

An anomalous origin of the entire coronary circulation from the right pulmonary artery is a very rare congenital malformation. We report on a male newborn presenting with hypoplastic aortic arch and coarctation of the aorta in whom a previously undetected single coronary artery originating from the right pulmonary artery was detected at the time of corrective surgery. The patient underwent a resection of the coarctation with a patch enlargement of the aortic arch and a successful reimplantation of the coronary artery into the aorta.
