Abstract in Portuguese
A ablação cirúrgica por radiofreqüência (RF) é uma nova técnica para tratar a fibrilação atrial (FA) permanente. O objetivo deste estudo é avaliar a eficácia da ablação cirúrgica por RF da FA permanente em pacientes com valvopatia mitral reumática (VMR). Entre Fevereiro de 2002 e Abril de 2003, 70 pacientes com FA permanente e VMR foram submetidos à operação da valva mitral associada à ablação por RF da FA (Grupo A); ou à operação da valva mitral isolada (Grupo B). No seguimento pós-operatório foram avaliados: a reversão para o ritmo sinusal (RS) e a contratilidade atrial. Após 12 meses de seguimento, os índices de reversão para o RS e de restabelecimento da contratilidade atrial foram significativamente superiores no Grupo A. A ablação cirúrgica por RF é eficaz para o tratamento da FA permanente em pacientes com VMR

Abstract in English
Radiofrequency ablation is a new surgical technique to treat permanent atrial fibrillation. The aim of this study was to evaluate the effectiveness of the (RF) ablation for the treatment of permanent AF in patients with rheumatic mitral valve (MV) disease. Between February 2002 and April 2003, 70 patients with permanent AF and rheumatic MV disease were assigned to undergo a MV surgery associated with RF ablation (Group A), or MV surgery alone (Group B). After 12 months of follow-up, the cumulative rates of sinus rhythm conversion and atrial transport function restoration were higher in Group A.The RF ablation is effective for treating permanent AF associated with rheumatic MV disease
