射频消融治疗小儿室上性心动过速安全性及疗效评价

Assessment of safety and efficacy of radiofrequency catheter ablation in the treatment of supraven- tricular tachycardia in children

目的对于儿童阵发性室上性心动过速(PSVT)是否应用射频消融治疗尚存在不同意见,本组回顾分析167例婴幼儿及儿童射频消融结果,评价射频消融术的安全性及疗效。方法选择频发室上性心动过速药物治疗无效或愿接受射频消融术治疗者,常规导管插管行电生理检查并标测消融耙点。结果 167例儿童一次成功率97.6%,其中房室结折返性心动过速成功率100%,并发症<1%,随访观察无 X 线放射反应,对生长发育无不良影响。结论射频消融术治疗儿童室上性心动过速是安全的、有效的,可做为部分首选治疗方案在临床应用,但应在有通过学习训练合格的医师的单位开展。

Objectives Whether radiofrequency catheter ablation(RFCA)could be used to treat paroxysmal supraventricular tachycardia(PSVT)in children was still a controversial subject.To assess the safety and efficacy of RFCA in children,we retrospectively analyzed the results of RFCA in 167 children. Materials and Methods The subjects included 167 children suffering from frequent episodes of PSVT.RF- CA was performed when PSVT was refractory to drugs or the children's parents wished to receive interven- tional treatment.Catheters putting,electrophysiological study,mapping and ablating were done routinely. Results The total primary success rate was 97.6%.The success rate of atrioventricular nodal reentry tachycardia was 100 %.The complication rate was less than 1%.During the follow-up,there was no radia- tive reaction of X-ray or side effects on growth and development seen.Conclusion RFCA was safe and ef- fective in the treatment of PSVT in children.It could be clinically used as the first selection of therapy in some patients.But it should be emphasized that,in children,RFCA could be used only in some hospitals, where doctors had passed learning-curve.
