Safety and efficacy of MitraClip™ therapy in patients with severely impaired left ventricular ejection fraction: results from the German transcatheter mitral valve interventions (TRAMI) registry

Aims The aim of the present study was to assess the safety and efficacy of percutaneous mitral valve repair using the MitraClip™ device in patients with severely reduced systolic left ventricular (LV) function. Methods and results Among 777 MitraClip™ implantations included in the German mitral valv...

Zusammenfassung:Aims The aim of the present study was to assess the safety and efficacy of percutaneous mitral valve repair using the MitraClip™ device in patients with severely reduced systolic left ventricular (LV) function. Methods and results Among 777 MitraClip™ implantations included in the German mitral valve registry, we identified 256 patients suffering from severely reduced LV function [ejection fraction (EF) 50%) and 280 patients presenting with an EF 30–50% prior to MitraClip™ therapy. High procedural success rates, low periprocedural complication rates, and low residual mitral regurgitation grades at discharge were achieved throughout all groups. In‐hospital mortality was low and comparable in all groups. After 1 year, mortality rates were 24.2% (EF 50%). Major adverse cardiac or cardiovascular event rates were 29.7% (EF 50%). Procedural failure was the main predictor for mortality in EF
