摘　　要：目的:评价Swartz鞘管在右侧房室旁路标测和消融中的应用价值。方法:25例右侧房室旁路消融失败或消融后复发患者,经Swartz(SR0)长鞘进行心内膜的标测与消融。观察消融即刻成功率、手术时间、消融时间和X线曝光时间以及并发症的发生情况。通过随访,评价导管消融后的远期效果。结果:消融术中证实,24例为右侧游离壁房室旁路,1例为右后间隔房室旁路。经Swartz鞘管进行标测、消融,术中均成功阻断房室旁路,未出现并发症。手术时间(2.1±1.1)h,旁路阻断时间(6.2±0.4)s,X线曝光时间(20.0±2.8)min,放电时间(120±25)s,平均放电次数(2.1±0.2)次。随访6个月,均未有复发。结论:采用Swartz鞘管进行右侧房室旁路的标测与消融有助于提高消融成功率,减少射线暴露和手术时间。Aim ： To evaluate the application value of Swartz sheath during mapping and ablation of right-side accesso- ry pathway（RAP）. Methods：A total of 25 patients with failed RAP ablation or recurrence after prior ablation were underg- one second ablation via Swartz sheath. The acute success rate of ablation, operation time, fluoroscopy time and complica- tion were observed. The long term efficacies of ablation were also studied. Results：The ablation was performed successfully in all the patients, in whom 24 were RAP of free wall and one was posteroseptal RAP. The operation time, blocking time and fluoroscopy time were （2.1 ±1.1 ） h, （6.2 ± 0.4） s and （20.0± 2.8 ） min, respectively. No recurrent patients were observed during 6-month fo!low-up. Conclusfon ： Mapping and ablation via Swartz sheath will improve the efficacy of RAP ablation, and reduce fluoroscopy and operation time.
