The recently published "electrophysiologically guided low-voltage bridge (LVB) strategy" is effective in the ablation of atrioventricular nodal re-entry tachycardia (AVNRT) in children. This study aimed to evaluate its efficacy and safety in children <26 kgs. Fourteen children [64% males, median age 6.5 years (IQR 6-8 years), median weight 25.5 kg (IQR 24-26 kg)] with AVNRT were treated. In all patients, we detected a LVB associated to a typical slow pathway potential. The acute success rate was 100% with a mean of 5.5 cryoablation deliveries. All procedures were performed with near-zero fluoroscopic exposure (median time 0.15 min, IQR 0-0.7 min), in six patients fluoroscopy was 0 min. There were no complications or recurrences during the follow-up (median 20.91 months, IQR 11.7-26.7 months).
最近发表的“电生理引导的低压桥（LVB）策略”在儿童房室结折返性心动过速（AVNRT）的消融中是有效的。本研究旨在评估其在<26 公斤儿童中的疗效和安全性。14 例 AVNRT 患儿[64%为男性，中位年龄 6.5 岁（IQR 6-8 岁），中位体重 25.5 公斤（IQR 24-26 公斤）]接受了治疗。在所有患者中，我们检测到与典型慢径电位相关的 LVB。急性成功率为 100%，平均 5.5 次冷冻消融。所有手术均在接近零射线暴露下进行（中位数时间 0.15 分钟，IQR 0-0.7 分钟），在 6 例患者中射线暴露为 0 分钟。在随访期间无并发症或复发（中位数 20.91 个月，IQR 11.7-26.7 个月）。
