[Surgical repair of bilateral atrioventricular valves in corrected transposition of the great arteries]

Abstract

The patient was a 50-year-old man who had an SLL-type corrected transposition of the great arteries (C-TGA) accompanied by significant regurgitation of the bilateral atrioventricular valves, atrial septal defect (ASD), persistent left superior vena cava, atrial fibrillation, and ventricular extrasystoles. The systemic tricuspid valve was repaired with a 28 mm Carpentier-Edwards ring (C-E ring) for the mitral valve, while the systemic mitral valve was repaired with a 32 mm C-E ring for the tricuspid valve. Simultaneously, the associated ASD was closed. Although mild tricuspid valve regurgitation persisted postoperatively, his general condition greatly improved. The report of valve repair for both atrioventricular valves in C-TGA is rare, and only 6 such cases have been reported in the Japanese literature.
