What is a “good” result after transcatheter mitral repair? Impact of 2+ residual mitral regurgitation

Abstract Objective The study objective was to assess the impact on follow-up outcomes of residual mitral regurgitation 2+ in comparison with ≤1+ after MitraClip (Abbott Vascular Inc, Santa Clara, Calif) repair. Methods We compared the outcomes of mitral regurgitation 2+ and mitral regurgitation ≤1+...

Zusammenfassung:	Abstract Objective The study objective was to assess the impact on follow-up outcomes of residual mitral regurgitation 2+ in comparison with ≤1+ after MitraClip (Abbott Vascular Inc, Santa Clara, Calif) repair. Methods We compared the outcomes of mitral regurgitation 2+ and mitral regurgitation ≤1+ groups among a population of 223 consecutive patients with acute residual mitral regurgitation ≤2+ who underwent MitraClip implantation at San Raffaele Scientific Institute (Milan, Italy) between October 2008 and December 2014. Results Residual mitral regurgitation 2+ was found in 64 patients (28.7%). Overall actuarial survival was 63.1% ± 4.4% at 48 months. Cumulative incidence functions of cardiac death in patients with mitral regurgitation 2+ was significantly higher (Gray test P
