Transcatheter mitral valve repair: a brief review.

Surgical treatment of mitral regurgitation has evolved from mitral valve replacement to repair, because the latter produces superior long-term outcomes. In addition, mitral valve repair can be achieved through minimally invasive approaches. The desire for less invasive approaches has driven the field of percutaneous mitral valve repair. Various technologies have emerged and are at different stages of investigation. So far, only the MitraClip device has been tested in large numbers of patients, whereas the reproducibility and the real effectiveness of the other devices still remain to be demonstrated.
