BACKGROUND: @entity955 is frequent in surgical @entity1 with @entity299 . Radiofrequency energy applied by means of surgical probes permits the reproduction of atriotomies described in the maze surgical procedure for the ablation of @entity955 in a fast, safe and efficient way. This study presents our initial experience in treatment of chronic @entity955 through radiofrequency performed in @entity1 with surgical @entity299 . @entity1 AND METHOD: From June to November 2000, 10 @entity1 , with surgical indications of valvulopathy, were intraoperatively treated through radiofrequency for its @entity955 . Ablations were performed in the right auricle from the epicardium before starting extra corporeal circulation, and in the left auricle from the endocardium, while under circulation. Radiofrequency was applied through a surgical multielectrode probe. RESULTS: Eight @entity1 (80%) presented some type of postoperative @entity943 , with relapse of @entity10689 in 3 @entity1 and flutter in another one. At discharge, none of the @entity1 presented relapse of chronic @entity955 . There was no in-hospital mortality. After a mean follow-up of 3 months (range 1-6), 8 @entity1 (80%) have recovered and maintained sinus rhythm. Only one @entity1 has re-established echocardiographic biatrial contraction. CONCLUSIONS: Intraoperative radiofrequency has allowed us to perform the @entity75 , in both auricles, in a simple way, with an initial effectiveness of 80%. Epicardial ablation of the right auricle was simple and safe. Although no @entity1 presented relapse of chronic @entity955 at hospital discharge, postoperative @entity943 have continued to be the main postsurgical problem.
