This multicenter RCT study evaluated the efficacy of medical therapy plus transcatheter valve repair (MitraClip) to medical therapy alone for heart failure accompanied by secondary moderate to severe mitral regurgitation.
The device group experienced significantly fewer hospitalizations and lower mortality at 24 months follow-up.
Neither surgical repair nor surgical replacement of the mitral valve has been shown to lower the rate of hospitalization or death associated with secondary mitral regurgitation, and both procedures confer a substantial risk of complications.
Why are there the difference between surgery and MitraClip?
If surgery is too invasive, the mortality of surgical survivor must be improved.
According to MR improvement, MVR must be better than MVP and Mitraclip. But there were no differences between MVR and MVP.
I doubt some limitations affect the results.
1. Abbot's trial It might cause COI.
2. F/U doctors know who are MitraClip patients due to XP.
