  Figure 2. Cardiac Computed Tomography Cardiac computed tomography demonstrated thickened mitral valve leaflets.

  Figure 3. Transesophageal Echocardiography (A and B) Baseline imaging. (C and D) Following percutaneous balloon mitral valvuloplasty with a 26-mm balloon. (E and F) Initial positioning of MitraClip NT across the anterior leaflet tear. (G and H) Final procedural outcome.

  Figure 4. Peri-Procedural Cineangiography (A) Baseline left ventriculography demonstrated no mitral regurgitation. (B) Following percutaneous balloon mitral valvuloplasty there was severe mitral regurgitation.

  Figure 5. Left Atrial Pressure Recordings (A) At baseline the V-wave was 51 mm Hg. (B) Following percutaneous balloon mitral valvuloplasty the V-wave increased to 74 mm Hg. (C) Following intervention with an NT device the V-wave reduced to 48 mm Hg.

  Figure 6. Operative Findings The mitral valve leaflets are thickened and the mitral valve orifice is significantly reduced. The anterior mitral valve leaflet tear has been reduced by the clip.
