单导管射频消融治疗频发房颤的预激综合征

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

采用单导管射频消融法治疗１２ 例预激综合征（ Ｗ Ｐ Ｗ） 。１２ 例中８ 例有反复快速性房颤史，３ 例须用同步直流电复律，１ 例伴有晕厥。旁路分别为左侧８ 条，右后间隔２ 条，右后侧及右前间隔各１ 条，右侧者有１ 例并存１ 条左侧隐匿旁路。全部旁路一次消融成功。术中未诱发房颤。随访５ ～１７ 月未见复发。

Twelve patients with WPW were treated by single catheter ablation. Eight patients had the histories of recurrent rapid atrial fibrillation(Af) and refractory to antiarrythmic 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.
