- Title:
- Beyond the 10-Year Horizon: Mitral Valve Repair Solely With Chordal Replacement and Annuloplasty.
- Abstract:
- BACKGROUND: The long-term outcomes of mitral valve repair by nonresection techniques, such as annuloplasty and chordal replacement, for degenerative mitral valve regurgitation were investigated. METHODS: All consecutive patients with degenerative mitral regurgitation who received solely chordal replacement and annuloplasty for mitral valve repair between 2003 and 2010 at the German Heart Center Munich were reviewed. The endpoints of this retrospective study were survival, cumulative incidence of reoperation on the mitral valve, and cumulative incidence of significant recurrent mitral regurgitation. RESULTS: A total of 346 patients were evaluated. The median follow-up period was 10.86 (range, 0.01-15.86) years. The 30-day mortality rate was 0.58% (n = 2 of 346), whereas the 5-year survival was 92.97% ± 1.41%. At 5 years, cumulative incidence of recurrent mitral regurgitation was 6.87% ± 1.57% and cumulative incidence of reoperation on the mitral valve was 3.69% ± 1.05%. Survival at 10 years was 83.35% ± 2.15%. At 10 years, cumulative incidence of recurrent mitral regurgitation was 13.31% ± 2.22% and cumulative incidence of reoperation was 7.84% ± 1.55%. Cox regression analysis identified age, diabetes mellitus, and reduced left ventricular ejection fraction <55% as independent risk factors for death. Left ventricular ejection fraction <55% was revealed as independent risk factor for significant recurrent mitral regurgitation. CONCLUSIONS: This study demonstrated excellent long-term outcomes with low incidence of reoperation after mitral valve repair using chordal replacement in a highly selected patient cohort. Our findings emphasized the importance of early intervention in severe degenerative mitral regurgitation, especially in patients with reduced left ventricular ejection fraction.
