Results of mitral valve reconstruction in Viet Duc hospital

ABSTRACT

Background: Mitral valve diseases are the most frequent in the cardiac valvular acquired diseases. Valvuloplasty is a very good surgical treatment, also its techniques are difficult. Objective: (1) To describe features of valvular lesion and technique of valvuloplasty. (2) To evaluate the effects of these operations. Subject and Method: 95 cases of mitral valve reconstruction were studied and described retrospectively about pre- operative features, mitral valvuloplasty, and post-operative results. Results: Pre-operative cardiac failure >=2 nd level (NYHA) is 96.8%, with 100% of mitral valve insufficiency, 28.4% associated with valvular stenosis. Mean age of patient is 34.5 +/- 13.2. Each case must do an average 4/15 valvuloplasty techniques, the most frequent are: mitral valvular ring (67.4%), commissurotomy (57.9%), cordage section (45.3%)\u2026 Early post \u2013 operative result is very good: no mortality, mitral valvular function is improved significantly than pre-operative (p<0.001), no severe mitral stenosis or insufficiency. Long-term post operative control (3 months, 3 years, 5 years post \u2013 operation) present the stability of this valvuloplasty with high survival frequency (96.8% in 3 months, 96.2% in 3 years, 93.4% in 5 years), in the 78.5% ranges a good level, re-operation is only required in 3 cases with valvular replacement. Conclusions: Although the difficult technique of valvuloplasty \u2013 especially in rheumatic lesion, mitral valve reconstruction is a good and safe technique to treat the mitral valve diseases.
