Radiofrequency ablation is the treatment of choice for patients with Wolff-Parkinson-White syndrome and symptomatic tachyarrhythmias. The technique involves localising the pathway with multiple catheters at various sites followed by radiofrequency energy application at that site. Single catheter approach has been described for ablation of manifest left-sided accessory pathways. In this article, we report the ablation of accessory pathways in different locations in patients with Wolff-Parkinson-White syndrome by using a two-catheter approach. Twenty-three consecutive patients with symptomatic Wolff-Parkinson-White syndrome were taken up for radiofrequency ablation with this approach. Pathways could be successfully ablated in 11 out of 13 patients with left free wall, 5 out of 7 with right posteroseptal, one patient of left posteroseptal and each of the 2 patients of right mid septal locations giving an overall success in 19/23 (82.6%) patients. Hence, two-catheter approach can be used safely to ablate accessory pathways in different locations with high success rate, thus minimising the procedure time associated with conventional approach.
射频消融是预激综合征合并有症状性快速心律失常患者的首选治疗方法。该技术包括使用多根导管在不同部位定位传导通路，然后在该部位施加射频能量。单导管方法已被描述用于消融显性左侧旁路。在本文中，我们报告了采用双导管方法对预激综合征患者不同部位旁路进行消融的情况。连续23例有症状的预激综合征患者采用这种方法进行射频消融。13例左游离壁患者中有11例、7例右后间隔患者中有5例、1例左后间隔患者以及2例右中间隔患者中的每例患者的旁路均成功消融，23例患者中有19例（82.6%）总体成功。因此，双导管方法可安全用于消融不同部位的旁路，成功率高，从而将与传统方法相关的手术时间降至最低。
