Mitral Transcatheter Edge-to-Edge Repair in Ventricular Functional Mitral Regurgitation and Very Severe Left Ventricular Dysfunction

Background Patients with functional mitral regurgitation (MR) and very severe left ventricular (LV) dysfunction (LV ejection fraction [LVEF] <20%) have been largely excluded from randomized trials of mitral transcatheter edge-to-edge repair (M-TEER), leaving a substantial knowledge gap regarding the role of M-TEER in t...
