    Abstract:
    The surgical treatment for ischemic mitral regurgitation remains controversal. Ring annuloplasty results in recurrent mitral regurgitation in some cases. Strut chordal cutting is a new surgical procedure in addition to ring annuloplasty for ischemic mitral regurgitation. Two patients (63-year-old woman, 53-year-old man) with severe ischemic mitral regurgitation were treated with this procedure. The patients had congestive heart failure due to mitral regurgitation, associated with inferior myocardial infarction. Regurgitant fraction of mitral regurgitation was 70% and 52% before surgery. Mitral leaflet tethering caused by apical displacement of the papillary muscle was observed. Mitral valve repair was performed by ring annuloplasty and chordal cutting. Intraoperative echocardiography showed that chordal cutting improved the configuration of the anterior leaflet, resulting in good mitral valve coaptation without regurgitation.
