Very long-term results (up to 17 years) with the double-orifice mitral valve repair combined with ring annuloplasty for degenerative mitral regurgitation

摘要: Objective The very long-term results of the double-orifice mitral valve repair are unknown. aim this study was to assess late clinical and echocardiographic outcomes technique in patients with degenerative regurgitation. Methods From 1993 2000, 174 severe regurgitation were treated combined ring annuloplasty. Mean age 52 ± 12.8 years, New York Heart Association class I or II present 71% patients, atrial fibrillation 17.2%, preoperative left ventricular ejection fraction 59.5% 7.5%. Mitral due anterior leaflet prolapse 36 (20.6%), bileaflet 128 (73.5%), posterior 10 (5.7%). Results There no hospital deaths. At discharge, absent mild 169 (97.1%) moderate (2+/4+) 5 (2.8%). stenosis requiring reoperation detected 1 patient (0.6%). Clinical follow-up 97.1% complete (mean length, 11.5 2.53 years; median, 11.6 longest duration, 17.6 years). 14 actuarial survival 86.9% 3.37%, freedom from cardiac death 95.8% 1.54%, 89.6 2.51%. last examination, recurrence ≥3+ documented 23 (23/169, 13.6%). Freedom at years 83.8% 3.39%. only predictor residual greater than discharge (hazard ratio, 5.7; 95% confidence interval, 1.6-20.6; P  = .007). Conclusions annuloplasty provides satisfactory setting prolapse.
