Moderate to severe functional mitral regurgitation (FMR) is sometimes, but not always, reduced with cardiac resynchronization therapy (CRT). Auricchio and colleagues evaluated the efficacy of MitraClip (Abbott Vascular, Redwood City, California) treatment on symptoms and left ventricular remodeling in CRT nonresponders with FMR. MitraClip treatment was feasible in all 51 patients, but there were 2 periprocedural deaths. New York Heart Association functional class improved acutely. The proportion of patients with moderate or greater FMR also decreased, and it was associated with reverse remodeling. FMR treatment with MitraClip in CRT nonresponders is feasible, safe, and appears to promote reverse remodeling.

Abstract
Moderate to severe functional mitral regurgitation (FMR) is sometimes, but not always, reduced with cardiac resynchronization therapy (CRT). Auricchio and colleagues evaluated the efficacy of MitraClip (Abbott Vascular, Redwood City, California) treatment on symptoms and left ventricular remodeling in CRT nonresponders with FMR. MitraClip treatment was feasible in all 51 patients, but there were 2 periprocedural deaths. New York Heart Association functional class improved acutely. The proportion of patients with moderate or greater FMR also decreased, and it was associated with reverse remodeling. FMR treatment with MitraClip in CRT nonresponders is feasible, safe, and appears to promote reverse remodeling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
