Leaflet edge-to-edge treatment versus direct annuloplasty in patients for functional mitral regurgitation.
Interventional mitral repair techniques have evolved as safe and effective treatment options for patients with functional mitral regurgitation (FMR) at high or prohibitive surgical risk. Of the techniques available, the MitraClip device and Cardioband mitral repair system have been used most commonly. However, a direct comparison of the two devices, examining their effectiveness at reducing MR, reducing symptoms, and extending life expectancy, has not yet been performed. For this purpose, we compared the outcome of patients after direct annuloplasty by the Cardioband system with patients after edge-to-edge therapy with the MitraClip device in a propensity score-matched analysis.
