RESUMO

The objective of this study was to evaluate in retrospect, in long-term, the predictors of late recurrence of atrial fibrillation (AF) in 139 patients submitted to the ablation by radiofrequency, through the techniques ostial or extra-ostial of approach of the atrium left, associated or not to the ablation of the cavotricuspid isthmus(ICT). Variables pre, intra and post-ablation were appraised for analysis uni and multivariated, to determine the predictors of recurrence of AF after one procedure. It was observed that larger time of history of AF, use of more drugs and recurrence of AF within 60 days after procedure; they increased the risk of recurrence of AF in long-term. On the other hand, the association of atrial flutter and the concomitant ablation of ICT, they reduced the recurrence risk at the end of 33 ±12 months.
