摘要: 目的 通过比较Carto3系统指引零射线与X线下导管射频消融治疗特发性室性心律失常,评估零射线方法的有效性和安全性。方法 前瞻性收集由2017年1月至2018年3月于广西医科大学第一附属医院连续在Carto3系统指引下行导管射频消融术的特发性室性心律失常(包括特发性室性期前收缩和特发性室性心动过速)患者106例,根据手术日期的单双号进行分组。其中39例手术日为单号,纳入零射线组;67例手术日为双号,纳入射线组。所有手术均由2名术者完成,均使用强生导航星压力监测灌注消融导管。比较两组手术时间、首次标测时间、放电次数、放电时间、靶点位置、即刻成功率、并发症发生率、复发率。结果 两组年龄、性别、病程、超声心动图等基线资料差异无统计学意义。射线组使用X线时间为168.0(44.8, 541.3) s。两组在手术一般资料方面,手术时间、首次标测时间、放电次数、放电时间、靶点位置等差异均无统计学意义。两组在手术的有效性和安全性方面,即刻成功率、并发症发生率、复发率方面差异均无统计学意义(P>0.05)。结论 Carto3系统指引零射线下导管射频消融治疗特发性室性心律失常有效、安全,没有增加手术时间、首次标测时间及放电次数。

Abstract: Objective  To compare the catheter radiofrequency ablation for idiopathic ventricular arrhythmia guided  by Carto3 system with or without fluoroscopy,  so as to evaluate the efficacy and safety of zero fluoroscopy approach.Methods  A prospective study was performed among 106 consecutive patients of idiopathic ventricular arrhythmia (IVA,  including idiopathic premature ventricular contraction and idiopathic ventricular tachycardia) who were hospitalized from January 2017 to March 2018 in the First Affiliated Hospital of Guangxi Medical University. The catheter radiofrequency ablation was performed under Carto3 system guidance.According to the date of operation,  patients were randomly divided into two groups. Of them,  39 cases operated on odd numbers were included zero fluoroscopy group (ZF group),  and 67 cases on double numbers were included in fluoroscopy group (F group). All the procedures were performed with contact force catheter of Biosense Webster  by 2 operators. The difference between the two groups in terms of their procedure time,  first mapping time,  number of ablation,  ablation time, fluoroscopy time, target position, immediate success rate, complications and recurrence rate were compared.Results  There was no statistical difference in baseline data such as age, sex,  disease course  and echocardiographic index between the two groups. ZF group was performed completely without fluoroscopy, and the fluoroscopy time of F group was 168.0(44.8,541.3) s. In terms of general procedure data such as the procedure time, first mapping time, number of ablation, ablation time, target position, no statistical difference was found between the two groups. As to the effectiveness and safety of the operation between the two groups, the immediate success rate, complications  and recurrence rate had no statistical difference(P>0.05).Conclusion  Catheter radiofrequency ablation for idiopathic ventricular arrhythmias guided by Carto3 system without fluoroscopy showed efficacy and safety, without increasing  the procedure time, the first mapping time,  and the number of ablation.
