Does voltage-propagation mapping improve acute success or reduce recurrence compared to anatomical mapping in paediatric patients with AVNRT?
Voltage-propagation mapping is an effective alternative to traditional anatomical mapping for AVNRT ablation in pediatric patients, potentially requiring fewer ablations to achieve initial success.
Both techniques demonstrated an excellent acute success rate and a low recurrence rate. Voltage-propagation mapping trended toward fewer ablations to initial success and did not prolong the procedure time. This paediatric study suggests that both a traditional anatomical technique and a voltage-propagation technique can provide excellent clinical outcomes, especially for typical atrioventricular nodal re-entry tachycardia.
