title: [Re-do mitral valve repair].
abstract: We describe proper indication and results of re-do mitral valve (MV) repair for recurrence of mitral regurgitation( MR) after MV repair. Among 1,163 patients who received MV repair for MV prolapsed between October 1991 and December 2010, 70 patients (6.0%) underwent redo MV operation. Only 14 patients (20%) among them received re-do MV repair and other 56 patients( 80%) underwent MV replacement. One patients of the 7 patients( 50%) who received re-do MV repair in 3 months after the operation received mitral valve replacement( MVR) for recurrence of MR 2 months after re-repair. However, in other 6 patients, postoperative echodoppler study performed after discharge revealed none or only trivial MR. In 6 of 7 patients, the cause of recurrence was detachment of the sutureline and hemolysis was present in 5 patients. Re-do repair was considered good indication for those patients who showed recurrence MR due to localize detachment of the sutureline. On the other hand, predictability of the results of re-do repair for chronic recurrent MR was low. Our newly developed stentless MV (Normo) would be a good solution for those patients who showed recurrence of MR after MV repair having low fesibility of re-do MV repair.
