摘要:

目的 比较Carto3全三维标测系统指导下零射线射频消融术与常规X线射频消融术治疗阵发
性室上速的安全性和有效性。方法 连续入选2017年1月至2018年6月因阵发性室上性心动过速于西安交
通大学第二附属医院心内科住院且拟行射频消融治疗的患者102例,随机分为Carto3全三维标测组52例,
常规X线射频组50例。比较两组的手术时间、靶点标测时间、消融放电次数、X线曝光量、手术即刻成
功率以及手术并发症的差别。结果 两组患者手术即刻成功率及并发症无统计学差异(P均>0.05)。
Carto3全三维组的手术时间、靶点标测时间、消融放电次数、X线曝光量均显著低于常规X线组,差异
有统计学意义(P均<0.05)。结论 Carto3全三维标测系统指导下零射线射频消融治疗阵发性室上速患
者,手术有良好的安全性及有效性,具有重要的临床价值。

Abstract:

Objective To compare the safety and efficacy between zero-ray radiofrequency ablation (RFA)
guided by Carto3 total three-dimensional mapping system and routine X-ray RFA in treatment of paroxysmal
supraventricular tachycardia (PSVT). Methods The patients planed to undergo RFA (n=102) were chosen from
Department of Cardiology in the Second Affiliate Hospital of Xi’an Jiaotong University from Jan. 2017 to June
2018, and divided randomly into Carto3-RFA group (n=52) and X-ray RFA group (n=50). The differences were
compared in RFA time, target mapping time, ablation discharge times, X-ray exposure volume, immediate success
rate of RFA and incidence of complications between 2 groups. Results The immediate success rate of RFA and
incidence of complications had no statistical difference between 2 groups (all P>0.05). The RFA time, target
mapping time, ablation discharge time and X-ray exposure volume were all significantly lower in Carto3-RFA
group than those in X-ray RFA group (all P<0.05). Conclusion The safety and efficacy of zero-ray RFA guided by
Carto3 total three-dimensional mapping system are higher in treatment of PSVT, which has great clinical value.
