THE RELATIONSHIP BETWEEN THE MAGNITUDE OF REDUCTION IN MITRAL REGURGITATION SEVERITY AND LEFT VENTRICULAR AND LEFT ATRIAL VOLUMES POST-TREATMENT WITH THE MITRACLIP DEVICE

In EVEREST II RCT, MitraClip reduced mitral regurgitation (MR) severity safely but to a lesser degree than surgery. A premise of the trial was that a lower degree of MR reduction with MitraClip provides meaningful clinical benefit. Few data exist on the magnitude of MR reduction necessary to provide
