Abstract

Introduction: The mitral insufficiency as a result of the rheumatic fever in young population has important complications augmenting the morbidity and mortality of the valvar disease. In order to prevent mitral valve replacement, we designed a technique for correction of the mitral insufficiency, based in duplicating the coaptation surface of the posterior mitral leaflet.

Objectives: Describe anatomically the proposition technique for correction of the mitral insufficiency preserving the mitral valve.

Material and Methods: The technique designed is based in augmenting the coaptation surface of the mitral valve duplicating the posterior leaflet of the mitral valve; the approach to the mitral valve is via left atrium and the posterior leaflet is dissected from posterior annulus; the posterior annulus is diminished in diameter with stitches at the posterior mitral annulus; the mitral valve free from the edge is incised and divided in two leaflets (right and left posterior leaflets); near the anterior commissure the left leaflet is sutured to the mitral annulus portion and the right leaflet is sutured by running suture to the free edge of the left leaflet; after we tested the valve injecting electronic solution.

Conclusion: This technique promises to be a new proposition in the treatment of the mitral insufficiency, because is easy to do, but the appropriate timing of mitral plasty is the most important factor for the treatment and for the results.
