Emergency Transcatheter Repair for Anterior Leaflet Tear Following Percutaneous Balloon Mitral Valvuloplasty

Cameron Dowling et al. JACC Case Rep. .

Abstract

We present the case of a 66-year-old woman who developed severe mitral regurgitation from rupture of the anterior mitral valve leaflet following percutaneous balloon mitral valvuloplasty. Emergency transcatheter mitral valve repair was used to reduce the severity of mitral regurgitation and facilitate definitive surgical treatment. (Level of Difficulty: Advanced.).

Keywords: echocardiography; mitral valve; valve repair.

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.

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.
