The recently published "electrophysiologically guided low-voltage bridge (LVB) strategy" is effective in the ablation of AVNRT (atrioventricular reentry tachycardia) in children. This study aimed to evaluate its efficacy and safety in children <26Kgs. Fourteen children [64% males, median age 6.5 years (IQR 6-8 years), median weight 25.5kg (IQR 24-26kg) 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 minutes, IQR 0-0.7 minutes), in six patients fluoroscopy was 0 minutes. There were no complications or recurrences during the follow-up (median 20.91 months, IQR 11.7 - 26.7 months). This article is protected by copyright. All rights reserved.
