MitraClip Procedure in Advanced Heart Failure and Severe Mitral Regurgitation: Case Report and Literature Review.

Mitral regurgitation (MR) is a common valvular disorder often seen in a severely dilated left ventricle (LV) and reduced LV function. In chronic heart failure (HF), severe functional MR increases preload, wall tension, LV workload, and worsening prognosis. The MitraClip device offers a percutaneous treatment option in HF, although its safety and efficacy in advanced and acute HF remain a gray zone. We present a successful case of the emergent MitraClip intervention in a patient with advanced HF and review the relevant literature.
