title: [Aortic Valve Replacement Concomitant with Right and Left Ventricular Outflow Tract Repair Eight Years after Arterial Switch Operation for Double Outlet Right Ventricle;Report of a Case].
abstract: We report a case of successful aortic valve replacement and relief of right and left ventricular outflow tract obstruction 8 years after an arterial switch operation for double outlet right ventricle. Since the surgical access to the ascending aorta was limited because of the anatomical feature and the adhesion after the arterial switch operation, arterial infusion site for cardiopulmonary bypass was secured at the right common carotid artery ahead of the sternal re-entry. After cardiopulmonary bypass was established, the right pulmonary artery was divided and then dissection of the ascending aorta was completed to secure the space for aortic valve replacement. A discrete membrane of the left ventricular outflow and muscle bands of the right ventricular outflow were completely resected. The right pulmonary artery was reconstructed by interpose of a prosthetic graft. Our experience would provide a technical option how to handle complex late complications after the arterial switch operation.
