[Surgical mitral valvuloplasty in the treatment of mitral valve diseases].
Mitral valve repair surgery, in presence of a pure mitral leakage or one associated to a stenosis, is not only possible but has been well codified for a decade. According to damage, there are two methods of operation: valvular mobilization surgery and valvular motion amplitude reduction surgery. They are usually associated to annuloplasty with a Carpentier prosthetic ring. The incidence of late mortality is of 0.6 p. 100 pt/yr, that is to say 91.7 p. 100 at 13 years. This late survival rate is about 20 p. 100 better than for a valvular replacement. Reoperations rate is 1.6 p. 100 pt/yr. The incidence of thromboembolic event occurrence is low: 0.5 p. 100 pt/yr. The ideal indications for mitral valve repair are represented by damage of prolapse from a degenerative origin for which results are better and more constant. For rheumatic damage, the valvular repair indication depend on the valvular tissue elasticity and area. The presence of calcification and extensive fibrosis remain on principle counter-indications.
