An anterior longitudinal aortotomy with a distal aortic transection for the arterial switch operation

Abstract An additional longitudinal aortotomy on the anterior aspect of the old ascending aorta after distal aortic transection is very effective for removal of the coronary buttons, prevention of deformation of the neopulmonary arterial ring, and reconstruction of the neopulmonary arterial trunk after the Lecompte maneuver, especially for the neonatal arterial switch operation.
