Integrated reverse left and right ventricular remodelling after MitraClip implantation in functional mitral regurgitation: an echocardiographic study

Abstract

MitraClip implantation induces a significant reverse remodelling of LV, with reduction in both diastolic and systolic LV volumes and an increase in the cardiac index. The concomitant reduction in LV filling pressure, obtained after MitraClip implantation, reflects nearly immediately on the haemodynamics of the right sections. In fact, since discharge, we observed both a reverse remodelling of the right sections, with a significant reduction in SPAP, and a significant increase in longitudinal RV systolic function as shown by the increase in TAPSE and RV-Sm.
