Echographic outcomes of patients with atrial derived FMR (aFMR) and heart failure with preserved ejection fraction (HFpEF) were compared to patients with ventricular derived FMR (vFMR) and heart failure with reduced ejection fraction (HFrEF) after percutaneous mitral valve repair with the Carillon Mitral Contour System.
- Patients with aFMR showed similar reductions in mitral annulus diameter and concomitant reduction in regurgitant volume through 3 months compared to those with vFMR.
- Significant reduction in MR as assessed by vena contracta, effective regurgitant volume as well as MR was seen as soon as 3 months after procedure in both groups.
- Similarly, after 3 months the proportion of patients with NYHA class III or IV was reduced from 92.8% to 42.8% which was maintained throughout 12 month follow-up.
The Carillon device is feasible in HFpEF patients with aFMR and is associated with significant reductions in MR.
