| Popis: | For cases of initial suboptimal mitral valve repair, the edge-to-edge (EE) technique has been used as a bailout procedure. However the long-term durability of those rescued mitral valves is currently unknown. With this study we aim to evaluate the long-term clinical and echocardiographic results of the EE technique used to rescue patients with initial suboptimal conventional mitral valve repair.A retrospective review of our institutional database was done to query for patients who had undergone mitral valve repair with the EE technique used as a bailout procedure. The cumulative incidence function using death as a competing event was used to estimate cardiac death and redo for mitral valve replacement. To describe the time course of mitral regurgitation, we performed a longitudinal analysis using generalized estimating equations with random intercept for correlated data.Eighty-one patients were selected. The median follow-up was 9.1 years (interquartile range, 6.7-12.1; maximum, 22.6 years). At 15 years the estimated Kaplan-Meier overall survival was 63.2% ± 8.69% (95% confidence interval, 43.76-77.46) and the predicted rate of moderate to severe mitral regurgitation recurrence was 16.67%. At 15 years the cumulative incidence function for redo for mitral valve replacement with death as a competing event was 2.5% (95% confidence interval, 0.48-7.84). No case of more than mild mitral stenosis was detected.The EE technique can be effectively used as a bailout procedure in patients with suboptimal conventional mitral valve repair with satisfactory long-term results. |
