CARTO3零射线与常规X线下导管射频消融治疗室性早搏的疗效及安全性对比分析

Efficacy and safety of radiofrequency catheter ablation under CARTO3 zero-ray and conventional X-ray in treatment of ventricular premature beat:a comparative study

目的对比分析CARTO3零射线与常规X线下导管射频消融治疗室性早搏的疗效及安全性。方法对本院64例室性早搏患者的临床资料进行回顾性分析,根据资料中治疗方法的不同将其分为零射线组和常规组,观察其手术指标情况及术后不良反应情况,并分析2种手术方案的临床疗效及安全性。结果2组患者基本资料情况比较差异无统计学意义(P>0.05)。2组患者的手术时长比较差异无统计学意义(P>0.05)。与常规组比较,零射线组的标测用时、曝光时间更短,差异有统计学意义(P<0.05);零射线组的放电次数亦少于常规组,差异有统计学意义(P<0.05);零射线组发生1例术后复发、1例穿刺局部出血,常规组发生4例术后复发、1例心包压塞、2例穿刺局部出血,零射线组术后不良情况发生率低于常规组(6%与23%),差异有统计学意义(P<0.05)。结论与常规X线下导管射频消融相比,CARTO3零射线治疗室性早搏安全性更高,临床疗效显著,更能有效减少术后不良反应发生,增加治疗成功率。

Objective To compare and determine the efficacy and safety of radiofrequency catheter ablation under CARTO3 zero-ray and conventional X-ray in the treatment of ventricular premature beat(VPB).Methods The clinical data of 64 patients with VPB admitted to our hospital were retrospectively analyzed.According to the different treatment methods,all patients were divided into the zero-ray group and conventional group.The operation indexes and postoperative adverse reactions were examined,and the clinical efficacy and safety of the two surgical protocols were analyzed.Results There was no statistically significant difference in the basic data between the two groups(P>0.05).There was no significant difference in operation duration between the two groups(P>0.05).Compared with the conventional group,the mapping time and exposure time in the zero-ray group were shorter,with statistically significant differences(both P<0.05).The discharge frequency in the zero-ray group was less than that in the conventional group,with statistically significant difference(P<0.05).One case of postoperative recurrence and 1 case of puncture-induced local bleeding occurred in the zero-ray group.There were 4 cases of postoperative recurrence,1 of pericardial tamponade and 2 of puncture-induced local bleeding in the conventional group.The incidence of postoperative adverse events in the zero-ray group was lower than that in the conventional group(6%vs 23%),with statistically significant difference(P<0.05).Conclusion Compared with radiofrequency catheter ablation under conventional X-ray,CARTO3 zero-ray was safer and more effective in the treatment of VPB,which may effectively reduce postoperative adverse reactions and increase the success rate of treatment.
