Percutaneous edge-to-edge mitral valve repair. Current clinical evidence with the MitraClip System.

In the past few years, a myriad of technologies have been developed for percutaneous repair of the mitral valve for patients with severe mitral regurgitation (MR) and at high risk for traditional open-heart mitral valve surgery. Among them, MitraClip has emerged as the only clinically safe and effective method for percutaneous mitral valve repair. This device mimics the surgical edge-to-edge mitral valve repair initially described by Dr. Alfieri. In this article, we review the current clinical evidence on the use of the MitraClip--from the randomized control trial EVEREST II to the information derived from expert high-volume centers.
