Abstract
MitraClip therapy has been proposed as therapeutic option in selected patients with degenerative or functional mitral regurgitation (FMR), leading to clinical and prognostic benefits. Previous studies demonstrated the safety and the efficacy of MitraClip therapy on symptoms and left ventricular remodeling in cardiac resynchronization therapy (CRT) non-responder patients. We report a case of a CRT non-responder patient treated with MitraClip implantation followed by a new upgrading of the CRT for persistent FMR at the follow-up. The optimization of the interventricular delay, guided by echocardiographic parameters, resulted in a significant clinical and functional benefit. Echo-guided CRT upgrading can provide additive efficacy for patients in whom MitraClip implantation does not significantly improve FMR and symptoms.
