Anomalous origin of the right pulmonary artery from the ascending aorta: successful surgical repair.

A case of isolated anomalous origin of the right pulmonary artery from the ascending aorta with severe pulmonary hypertension is reported. Surgical repair was achieved by anastomosis of the anomalous vessel to the pulmonary artery trunk using a continuous absorbable suture. Special emphasis is laid on the favorable postoperative evolution of the pulmonary hypertensive disease following the successful repair. The poor natural history of this uncommon congenital defect if untreated makes early corrective surgery imperative.
