ABSTRACT

From June 1987 to October 1990, nine patients with congenital mitral stenosis (CMS) underwent surgical correction through an apical left ventriculotomy. Seven patients had parachute mitral valve and two had other forms of CMS. The surgical treatment of the mitral valve apparatus starts from below: first the papillary muscle is split and the cordae are divided and fenestrated. Then, the commissurotomies were performed through the ventricles aspect of the mitral valve. Associated anomalies were corrected simultaneously. There was no in-hospital death and only one late death (nonrelated). The echocardiography showed non significant residual stenosis and normal global function of the left ventricle. In conclusion, the appical left ventriculotomy is a good approach for treatment of CMS.

RESUMO

Entre junho de 1987 e outubro de 1990, nove pacientes consecutivos, portadores de estenose mitral congênita (EMC) foram submetidos a correção cirúrgica. Sete tinham valva mitral em paráquedas e dois, outras formas complexas de estenoses. Em todos, a via de abordagem foi a ventriculotomia apical esquerda, sendo dividido, primeiramente, o músculo papilar; depois, as cordas e, finalmente, as cúspides. As lesões associadas foram corrigidas prévia ou simultaneamente. Todos os pacientes tiveram boa evolução imediata. Houve um óbito tardio não relacionado. O estudo ecocardiográfico seriado pós-operatório mostrou adequada função ventricular esquerda. Conclui-se que esta via é de escolha para tratar lesões estenóticas congênitas complexas da valva mitral.
