An intriguing case report of functional mitral regurgitation treated with MitraClip.

Functional mitral regurgitation (FMR) is frequent in patients with heart failure (HF). It develops as a consequence of left ventricle (LV) geometry alterations, causing imbalance between increased tethering forces and decreased closing forces exerted on the mitral valve apparatus during systole. FMR is known to change at rest and during effort, due to preload–afterload changes, myocardial ischemia, and/or LV dysfunction. Despite optimized medical therapy, an FMR can be responsible of shortness of breath limiting quality of life and decompensation. In this report, we present a case of dynamic FMR treated with MitraClip. MitraClip implantation is a successful and innovative opportunity for HF patients with FMR.
