三维标测指导下射频消融治疗儿童局灶性房速的评价

摘要

Objective:To observe the effect of catheter ablation under the guidance of CARTO in the treatment of children with FAT ,so as to improve treatment security .Method:116 children with FAT with an-tiarrhythmic therapy were randomly divided into 2 groups ,58 cases in each group ,the control group under the guidance of conventional mapping , while the observation group under the guidence of CARTO , all applied catheter ablation,treatment effects were compared ,follow-up for 6 to 12 months.Result:The mean operating time,the recurrence rate difference was not statistically significant ( P>0.05);ablation success rate of the ob-servation group was 100.00 %,which was higher than that in the control group (86.21%)(P<0.05);X-ray exposure time of the observation group was (9.9±2.3) min,which was shorter than that in the control group (21.3±8.6) min(P<0.01);exposure of the observation group was 27.5±4.3mGy1,less than that in the con-trol group of 84.9±10.5mGy1(P<0.05).Conclusion:Catheter ablation under the guidance of CARTO in the treatment of children with FAT ,can analyze quickly and accurately the mechanism ,success rate and security are higher .%目的：观察三维标测（ CARTO）指导下射频消融治疗儿童局灶性房性心动过速（ FAT）的疗效，提高其安全性。方法：将116例经抗心律失常治疗无效的FAT患儿随机分为两组，每组58例，对照组在常规标测指导下，观察组在CARTO指导下行射频消融，比较两组治疗效果，随访6－12个月观察复发情况。结果：两组手术时间、复发率比较差异无统计学意义（P＞0．05）；观察组消融成功率100％，高于对照组的86．21％（P＜0．05）；观察组X 线曝光时间为9．9±2．3min，短于对照组的21．3±8．6min（P＜0．01）；曝光量为27．5±4．3mGy1，小于对照组的84．9±10．5mGy1（P＜0．05）。结论：采用CARTO标测儿童FAT，可准确快速地分析FAT 机制，射频消融成功率及安全性较高。
