Percutaneous Mitral Valve Repair with the MitraClip System in Mitral Regurgitation Due to Mitral Annular Calcification.

ABSTRACT

Percutaneous valve repair with the MitraClip represents a new and promising therapeutic option for patients with severe mitral regurgitation (MR). Mitral valve prolapse and flail leaflet are two major causes of degenerative MR in patients who underwent the MitraClip procedure. Mitral annular calcification (MAC) is also a less-frequent cause of degenerative MR. Among patients with MAC, open surgical treatment or valvular replacement is the treatment of choice for severe MR. Herein we present a case with severe MR secondary to MAC in whom successful percutaneous valve repair was accomplished with the MitraClip system due to the high risk of open-heart surgery.
