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.

Video 3: Transthoracic echocardiography demonstrating the calcified posterior mitral annulus (parasternal short-axis view).

Video 4: Transesophageal echocardiography showing the calcified posterior mitral annulus (left ventricular outflow tract view).

Video 5: Transesophageal echocardiography demonstrating severe mitral regurgitation from the middle segments of both leaflets (A2 and P2 segments) (central 4C view).

Video 6: Post-procedural 2D TEE (left ventricular outflow tract view).

Video 7: Post-procedural TEE showing resolution of the severe mitral regurgitation (central 4C view).
