Abstract

Atrial fibrillation is frequently initiated during radiofrequency catheter ablation of accessory pathways, it has been generally believed that initiation of atrial fibrillation may complicate the localization of accessory pathway. Therefore, most centers currently perform cardioversion in order to continue the ablation session. The purpose of the present study was to assess the feasibility and the electrophysiologiccriteria for successful radio frequency catheter ablation of left sided accessory pathways during atrial fibrillation in patients with WPW-syndrome. Radiofrequency ablation was performed in 87 patients with left-sided manifest accessory pathways during atrial fibrillation (n = 16) or during sinus rhythm (n = 71). The criteria for localization of accessory pathways were recording of stable accessory pathway potentials, local ventricular activation preceding the onset of the intrinsic flection of the unipolar electrogram and a QS pattern of the unipolar electrogram. Overall, the accessory pathways were successfully interrupted in 85/87 patients (98%). During the first ablation procedure, abolishing of accessory pathways was achieved in 15 of 16 patients (94%) during atrial fibrillation compared to 64 of 71 patients (90%) during sinus rhythm (n.s.). The total procedure time and fluoro time was significantly shorter during atrial fibrillation than during sinus rhythm (161 +/- 91 min vs. 216 +/- 128 min, p < 0.05, and 31 +/- 24 vs. 41 +/-26 min. p < 0.05, respectively). Thus, it is feasible and very effective to perform radiofrequency ablation of left-sided manifest accessory pathways during atrial fibrillation. Precise localization of accessory pathway during atrial fibrillation seems even easier than during sinus rhythm as indicated by shorter procedure and fluoro times in the atrial fibrillation group.
