A conventional reoperation via sternotomy approach is associated with a higher risk of heart injury as compared with first time operation. We have applied a minimally invasive cardiac surgery (MICS) for valve reoperation in order to minimize dissection of sternal adhesions. We evaluated MICS for mitral reoperation in this report. We retrospectively analyzed 20 patients (group R) who underwent mitral reoperation via partial lower hemisternotomy(PLH) and 66 patients (group I) who underwent first time operation via PLH from July 1997 through March 2002. The two groups took similar operative and postoperative course. Only the time of surgery was significantly longer in the group R. There were neither any operative deaths nor any postoperative major complications in both groups. PLH for mitral reoperation were performed safely and obtained operative outcome similar to PLH for first time mitral operation. We conclude that PLH will be an alternative approach for mitral reoperation.
