BACKGROUND: Few reports have assessed differences in the durability of mitral and tricuspid bioprostheses after simultaneous implantation of the same bioprosthesis in both positions. We investigated the long-term outcome after simultaneous mitral valve replacement (MVR) and tricuspid valve supraannular implantation (TVSI) with the Carpentier-Edwards bioprostheses in patients with severe tricuspid regurgitation and advanced mitral valve disease. METHODS: Between 1982 and 1998, 37 patients in our hospital underwent MVR and TVSI with Carpentier-Edwards bioprostheses. The mean age of the patients was 55+/-11 years. The average postoperative follow-up was 7.9+/-4.5 years after surgery (range 0 to 14.6 years, 315.1 patient-years). The follow-up rate was 100%. We evaluated the actuarial survival rate, the actuarial freedom from structural valve deterioration (SVD) and reoperation, and postoperative complications. RESULTS: The overall actuarial survival rate at 13 years after the operation was 69%+/-31%. The actuarial freedom from SVD and reoperation in the mitral and tricuspid positions were 78+/-22 and 100% and 70+/-30 and 90%+/-10% (p = 0.03), respectively. No patient had systemic or pulmonary thromboembolism, or complications associated with fatal arrhythmia. CONCLUSIONS: These results suggest that the bioprostheses in the tricuspid position yield significantly better long-term results than those in the mitral position after simultaneous MVR and TVSI. |
