[Single-catheter approach to radiofrequency current ablation of accessory pathway in Wolff-Parkinson-White syndrome with recurrent rapid atrial fibrillation].

Twelve patients with WPW were treated by single-catheter ablation. Eight patients had the histories of recurrent rapid atrial fibrillation(Af) and refractory to antiarrhythmic agents. Ventricular rate varied between 250-300 bpm. Defibrillation was needed in three patients, and one had syncope. All patients were treated successfully by ablation of accessory pathway with single-catheter approach and no Af occurred during the procedures. This result suggests that the single-catheter ablation may be an effective and feasible treatment for these patients with WPW and may be helpful in avoiding Af in multiple-catheter introducing procedure.
