摘要
应用Swartz导管对26例(28条旁道)房室折返性心动过速(AVRT)病人(A组)进行射频消融术,右侧房室旁道16条,左侧旁道12条,并与52例(54条旁道)常规方法消融结果(B组)比较,结果显示,16条右侧房室旁道消融均获成功,平均消融功率(27.8±6.0)W(P>0.05),平均有效放电次数(3.4±3.2)次(P<0.05),X线照射时间19~46min(29.2±8.8min,P<0.001);左侧12条旁道11条消融成功(91.7%),平均消融功率(26.7±7.1)W(P>0.05),平均有效放电次数(2.6±1.7)次(P<0.05),X线照射时间20~49分(29.4±14.1min,P<0.05),无手术并发症发生。随访6~38个月无复发。结果表明Swartz鞘管可以减少复杂、疑难病例的射频消融放电次数、缩短X线照射时间。
26 cases (group A) with 28 atrioventricular accessory pathways (AP) (16 in the rightside and 12 in the left) were ablated with radiofrequency current using Swartz introducer comparingwith 52 cases (group B) with 54 APs using the regular method. The results showed 16 APs in the rightwere successfully ablated (100%), the mean energy was 27. 8+6. 0 Walts (P>0. 05), the mean effective discharge time was 3. 4+ 3. 2 (P<O. 05), the mean X-ray exposure time was 29.2+8. 8 min (1946 min) (P<0. 001 ), and 11 of the 12 APs in the left were ablated successfully (91.7% ), the mean energy was 26. 7+7. 1 Walts (P>0. 05), the mean effective discharge time was 2. 6+1. 7 (P<0. 05), themean X-ray exposure time was 29. 4+14. 1 min (20-49 min) (P<0. 05), there was no complicationsassociated with operations, and there was no recurrence during 6 to 38 month follow-up. It is suggestedthat the effective discharge time and X-ray exposure time of radiofrequency current ablation could be reduced using Swartz introducer.
