This study aimed at assessing left ventricular (LV), left atrial (LA) and right ventricular (RV) volumes in patients before and after MitraClip™ implantation by cardiac magnetic resonance imaging (CMR).
The MitraClip™ is a novel device for percutaneous mitral valve repair. Recent studies demonstrated a reduction of LV volumes after MitraClip™ implantation using echocardiography. CMR is currently the reference method to assess cardiac volumes but has not been used to assess LV remodeling after MitraClip™ implantation so far.
Twelve patients with functional (n=7) or degenerative (n=5) mitral valve regurgitation grade 3 to 4 underwent CMR at baseline (BL) before and at 6 month follow-up (FU) after successful MitraClip™ implantation. CMR protocol consisted of short- and long-axis slices using a steady-state-free-precession cine sequence for the assessment of LV, LA and RV volumes.
CMR enables reproducible measurements of cardiac volumes in patients with implanted MitraClip™ devices. Significantly decreased LV but unchanged LA and RV volumes were found at 6 month after successful MitraClip™ implantation.
