title: Surgical Correction of Truncus Arteriosus With Unusual Origin of the Right Coronary Artery.
abstract: An 11-year-old male with a diagnosis of truncus arteriosus (common arterial trunk) with origin of the right coronary artery anteriorly from the pulmonary segment of the common trunk underwent reparative surgery. The pulmonary trunk was long, and it had a kink with stenosis that protected the distal pulmonary vascular bed from elevated pressure. Adequate flow allowed well-developed distal branch pulmonary arteries. An oval incision was made in the pulmonary trunk, which created a flap. At its center was the right coronary artery. This flap, which remained attached to the aorta proximally, was then used to close the aortic defect. The segment of the pulmonary trunk with stenosis was resected. The patient's pericardium was used to fashion a valved conduit that was interposed between the right ventricle and the confluence of the pulmonary artery branches.
