MINIMALLY INVASIVE MITRAL SYRGERY：MITRAL VALVE REPAIR WITH A RIGHT-SIDED PARTIAL STERNOTOMY

We describe our concept and the results of mitral valve repair using a right-sided partial sternotomy. We performed mitral valve repair using this method in 50 patients with severe MR between April 1997 and October 1998. In 10 patients in whom good exposure was not attained, we changed to the ordinary full-sternotomy or T-shaped partial sternotomyprocedure. Forty patients with good exposure underwent successful mitral valve repair. The sites of repair were anterior in 15 cases, posterior in 16, and both in 9. There was no mortality, and intraoperative TEE performed in all 40 patients revealed that all had trivial or no regurgitation. The right-sided partial sternotomy (open door method) is a safe and useful method for minimally invasive valve Surgery. A better quality of life compared with traditional median sternotomy can be ensured for patients undergoing minimally invasive cardiac surgery only when receive the best-quality Surgery is performed.
