Minimally invasive or conventional edge-to-edge repair for severe mitral regurgitation due to bileaflet prolapse in Barlow's disease: does the surgical approach have an impact on the long-term results?

摘要: Objectives To evaluate whether the adoption of a right minithoracotomy operative approach had an impact on long-term results edge-to-edge (EE) repair compared to conventional sternotomy in patients with Barlow's disease and bileaflet prolapse. Methods We assessed 104 treated minimally invasive EE technique. An equal number median for same were used as control group. The inverse probability treatment weighting was create comparable distributions covariates that significantly different at baseline two groups. performed comparative analysis Results No hospital deaths observed. Follow-up 99.5% complete (median 11.3 years). cumulative incidence function (CIF) cardiac death 12 years, noncardiac competing risk, showed no difference between groups ( P = 0.87). At CIF recurrent MR ≥ 3+, 7% group 5% 0.30), recurrence 2+ 15 14%, respectively 0.63). type surgical not predictor death, reoperation, 3+ or 2+. Conclusions A does have negative effectiveness durability prolapse disease. Long-term outcomes are excellent, valvular performance remains stable over time evidence mitral stenosis.
