Abstract

The MitraClip system is used for patients with severe mitral regurgitation (MR) who are at high risk for open surgery. However, some patients need surgical revision for various complications. The acute outcome of MitraClip treatment for atrial functional MR (aFMR) is scarcely reported. Herein, we describe a rare case of an 80-year-old woman treated with a MitraClip for aFMR with mitral annular dilatation and failed leaflet adaptation. The patient suffered from single leaflet device attachment (SLDA) and posterior leaflet injury 3 days posttreatment. The patient successfully underwent mitral valve replacement. The postoperative pulmonary hypertension was markedly improved and the left atrial volume was reduced. A MitraClip should be carefully used for aFMR with mitral annular dilatation and failed leaflet adaptation as it may cause SLDA.
