EMCAPT study: the effect of MitraClip treatment on the mitral annulus and left atrial appendage evaluation by transoesophageal echocardiography.

The contraction and filling velocity of LAA, SPAP, MAD, and LAA landing zone dimension changed significantly immediately after the MitraClip procedure. Although these parameters are not related to composite outcome in our study, MAD, LAA diameter, and velocity need to be compared between successful and unsuccessful procedures to predict their clinical relevance.
