Therefore, additional procedures targeting the subvalvular tissue, such as approximation or suspension of papillary muscle, have been considered. Ischemic mitral regurgitation mainly results from tethering due to left ventricular enlargement, with varying severity among cases and difficult prediction of reverse remodeling. Residual mitral regurgitation affects prognosis, necessitating reliable regurgitation control during mitral repair procedure. In some cases, valve replacement with chordal preservation may be preferable. We performed mitral valve repair for severe ischemic mitral regurgitation due to leaflet tethering. The patient was a 75-year-old male who had an acute myocardial infarction 10 years prior, which led to the progression of ischemic cardiomyopathy. Anterior leaflet augmentation using an autologous pericardial patch, suspension of the papillary muscles, and implantation of an artificial ring were performed. Six years postoperatively, the mitral valve remains in good condition and left ventricular reverse remodeling is favorable, with no heart failure observed.
