Key result
Radiofrequency ablation of the slow pathway significantly decreased atrioventricular node conduction at 3.24 years follow-up compared to preablation (146.3 vs 190.9 bpm; P<0.001).

Ablation was associated with sustained AV nodal changes in pediatric AVNRT; extends prior observations but leaves open need for randomized confirmation.

Does radiofrequency catheter ablation of the slow pathway alter anterograde conduction properties in children with atrioventricular nodal reentrant tachycardia?
Absolute Event Rate: 146.3% vs 190.9%
p-value: p=<0.001
Radiofrequency ablation of the slow pathway in children with AVNRT results in long-term changes in AV nodal conduction properties while maintaining efficacy and safety.
Šileikienė et al. (2009) conducted an observational in Atrioventricular nodal reentrant tachycardia (n=30). Radiofrequency ablation of the slow pathway vs. Preablation baseline was evaluated on Atrioventricular node conduction (p=<0.001). Radiofrequency ablation of the slow pathway significantly decreased atrioventricular node conduction at 3.24 years follow-up compared to preablation (146.3 vs 190.9 bpm; P<0.001).
