  ABSTRACT: A case of abnormal chordae of the mitral valve (MV) associated with systolic anterior motion (SAM) is not commonly encountered in clinical practice. Here we report MV repair via the edge-to-edge technique in a 56-year-old male with MV regurgitation associated with papillary muscle displacement and posterior leaflet prolapse. Echocardiography revealed obstruction of the left ventricular outflow tract caused by SAM because of papillary muscle displacement and mitral regurgitation associated with posterior leaflet prolapse due to chordae rupture. MV repair was successfully performed by reconstruction with an Alfieri stitch. The outcome of this case demonstrated that this surgical technique is preferable for MV abnormalities with no complex malformations.
