摘要
目的探讨经导管射频消融术治疗儿童室上性心动过速的安全性和有效性。方法回顾分析了本院39例室上性心动过速儿童射频消融治疗情况。结果 39例患儿均未发现器质性心脏病,其中男21例,女18例;年龄4.7～18.4(11.0±3.5)岁。心内电生理检查证实房室折返25例(64.1%),房室结折返11例(28.2%),持续性房速3例(7.7%)。25例房室折返患儿中,显性旁道12例,隐匿性旁道13例;左侧游离壁旁道9例,右侧游离壁旁道8例,右侧间隔旁道8例。本组消融成功率37例(94.9%),2例复发(5.1%),术后随访所有患儿无消融相关并发症的发生。结论经导管射频消融术治疗儿童室上性心动过速是安全、有效的。
Objective To assess efficacy and safety of radiofrequency catheter ablation for su- praventricular tachycardia in pediatric patients. Methods A retrospective study was made in a total of 39 pediatric patients, who underwent radiofrequency catheter ablation for supraventricular tachy- eardia in our institute. Results Structural heart disease was excluded in all of the patients, including 21 boys and 18 girls, with mean age 11.0 ± 3.5 years （range 4.7 to 18.4 years）. Electro- physiologic studies revealed atrioventricular reentry, atrioventricular nodal reentry and ectopic atrial tachycardia in 25, 11 and 3 patients, accounting for 64.1% , 28.2% and 7.7% , respectively. Among 25 patients with atrioventrieular reentry tachyeardia, 12 patients had Wolff-Parkinson-White accessory pathway and the other 13 patients had concealed pathway. The involving pathways located in left free-wall, right free-wall and right septum were identified in 9, 8 and 8 patients respectively. Ablation success was achieved in 37 patients （94. 9% ） and recurrence occurred in 2 patients （5.1%）. No complication was found. Conclusions Our primary experience indicated radiofrequeney catheter ablation is a safe and effective therapy for children with supraventricular tachycardia.
