Objective To summarize the experience and results of mitral annuloplasty with modified partial flexible artificial ring. Methods Two hundred and fifteennine patients were underwent partial flexible ring annuloplasty after mitral valve plasty surgery in our hospital from an. 1998 to Aug.2006. The etiology included rheumatic (16 cases), infective endocarditis of mitral (16 cases), ischemic (13 cases), ongenital (40 cases) and degeneration (174 cases). Echocardiogram test were performed in the perioperative periods to monitor the lefe atrium (LA), left ventricular enddiastolic dimension (LVEDD), left ventricular endsystolic dimension (LVESD), left ventricular ejection fraction(LVEF), left ventricular fractional shortening (LVFS) and mitral regurgitation grades. The perioperative mortality, morbidity, reoperation rate were recorded during the followup. Results Aortic cross clamping time was 74±30 min and cardiopulmonary bypass time was 105±37min. The perioperative survival rate was 96.5% (250/259) and free from complications rate was 93.4% （242/259）. No left ventricular out flow tract obstruction and coronary artery stenosis were occurred in this group. The 60 months survival rate was 938% (243/259) and 5 years nonreoperation rate was 96.1%(249/259). The perioperative echocardiogram results showed the LVEDD decreased from 62.60±10.19mm to 52.88±8.67mm and the LVEF increased from 57.91% to 61.00%（P lt;0.05）. During the followup the mitral regurgitation grades were improved significantly (P lt;0.05),there were 188 cases of trifle mitral regurgitation (72.6%), 62 cases of mild mitral regurgitation (23.9%), 8 cases of moderate mitral regurgitation(3.1%) and 1 case of serious mitral regurgitation(0.4%). Conclusion This simplified mitral annuloplasty technique is an easy handling and effective treatment for the mitral repair.
