Radiofrequency ablation (RFA) in children is an increasingly common practice.
To evaluate, in our institution, the results of RFA in children younger than 15 years.
A total of 125 children submitted to RFA between May 1991 and May 2010 were analyzed.
Sixty-seven (53.6%) children were males, aged between 44 days and 15 years (mean 8.6 ± 3.3 years) with median weight of 31 kg. Heart disease was present in 21 (16.8%) patients. The RFA of accessory pathways (AP) was the most common procedure (62 children - 49.6%). The RFA of nodal reentrant tachycardia (NRT) was the second most common arrhythmia in 27 (21.6%), followed by atrial tachycardia (AT) in 16 (12.8%) and ventricular tachycardias (VT) in 8 (6.4%) children. The success criteria were achieved in 86.9%, 96.1%, 80% and 62.5% of patients undergoing RFA of AP, NRT, AT and VT, respectively. Transient AVB occurred during RFA in 4 (3.2%) and LBBB in 7 (5.6%) children. Twenty-five children underwent a new RFA due to initial failure or recurrence. During the mean follow up of 5.5 ± 3.4 years, 107 (88.4%) remained without recurrence. There was no statistical difference regarding the results and the age at which the patient underwent the procedure. No child had persistent AVB or required a permanent pacemaker.
Catheter ablation is a safe and effective alternative therapy in children with recurrent tachycardias refractory to medical treatment.
射频消融（RFA）在儿童中是一种越来越常见的治疗方法。
在我们的机构中评估 RFA 在 15 岁以下儿童中的结果。
分析了 1991 年 5 月至 2010 年 5 月期间接受 RFA 的 125 名儿童。
67 名（53.6%）患儿为男性，年龄 44 天至 15 岁（平均 8.6±3.3 岁），中位数体重为 31kg。21 名（16.8%）患儿存在心脏疾病。最常见的 RFA 程序是旁路（AP）消融（62 名患儿-49.6%）。其次是房室结折返性心动过速（NRT）消融（27 名患儿-21.6%），接着是房性心动过速（AT）消融（16 名患儿-12.8%）和室性心动过速（VT）消融（8 名患儿-6.4%）。AP、NRT、AT 和 VT 消融的成功率分别为 86.9%、96.1%、80%和 62.5%。4 名（3.2%）患儿在 RFA 过程中出现短暂性房室传导阻滞，7 名（5.6%）患儿出现左束支传导阻滞。25 名患儿因初始失败或复发接受了新的 RFA。在平均 5.5±3.4 年的随访中，107 名（88.4%）患儿无复发。手术时的年龄与结果之间无统计学差异。无患儿出现持续性房室传导阻滞或需要永久性起搏器。
对于药物治疗无效的复发性心动过速患儿，导管消融是一种安全有效的替代治疗方法。
