[A surgical case of papillary muscle reconstruction and double-CABGs for mitral regurgitation due to ruptured papillary muscle after myocardial infarction].
A 76-year-old female patient underwent papillary muscle reconstruction, and d-CABGs a month after the onset of myocardial infarction. Posterior papillary muscle (PPM) was recognized to be ruptured partially, its stump was sewn to original PPM. An ePTFE suture (CV 5) was placed from anterior mitral leaflet to anterior papillary muscle in attempt to reinforce PPM-repair. Carpentier-Edwards ring was inserted and d-CABGs (LITA to LAD and GEA to RCA) were performed, simultaneously. Postoperative examination revealed no regurgitation and no stenosis of bypass grafts during follow-up period of 5 months after the procedure. Papillary muscle reconstruction was effective procedure for MR due to the ruptured papillary muscle.
