OBJECTIVE: To describe the experience with the technique of posterior leaflet extension in children suffering of rheumatic mitral regurgitation.
METHODS: Between April 2002, and October 2007, 30 children, mean age 11.3 years, underwent correction of mitral insufficiency with the technique of posterior leaflet extension with a pericardial patch. Eight also received a Carpentier ring. Six children had aortic valve disease and were submitted to Ross operation (five cases) or valve replacement with an aortic homograft. All were in functional class III or IV (NYHA classification).
RESULTS: There was one death. One child presented severe hemolysis in the postoperative period and was submitted to mitral valve replacement. Clinical evolution in the remaining patients was good.
CONCLUSIONS: Posterior leaflet extension of the mitral valve seems to be an effective surgical technique for correction of rheumatic mitral insufficiency in children.
