Opinion Statement:
Surgical mitral valve (MV) repair remains the gold standard to treat patients with significant degenerative mitral regurgitation (DMR). Medical therapy was the only option for patients found to be not appropriate for MV surgery until the development of percutaneous/transcatheter MV repair options that now allow to reduce MR less invasively and safely. This article discusses the basic mechanisms of MR and the rationale for MR intervention and offers a detailed review on percutaneous/transcatheter MV repair with the MitraClip.
