[Corrected transposition of the great arteries with associated tricuspid valve incompetence--report of a case of successful tricuspid valve replacement].

A 36-year-old woman with corrected transposition (C-TGA) of great arteries with associated systemic atrioventricular valve (A-V valve) regurgitation was presented. Cineangiography revealed that the right sided ventricle was morphologic left ventricle, and left sided ventricle was morphologic right ventricle. In addition, severe systemic A-V valvular regurgitation (Sellers IV) was demonstrated. Under the diagnosis of C-TGA with associated A-V valvular regurgitation, left sided atrioventricular valve replacement was performed using 29 mm SJM valve. Left sided atrioventricular valve was tricuspid valve (TV). A part of the anterior tricuspid leaflet and two pieces of papillary muscle was resected. Postoperative course was uneventful. The pathological findings indicated that valvular tissue had myxomatous degeneration.
