Key result
Contact-force RF ablation for pediatric AVNRT is linked to 100% acute success vs conventional catheters.
Why the study?
Despite increasing use of irrigated contact-force sensing catheters in adult populations, data regarding their use in pediatric AVNRT remain limited.
Does irrigated contact-force sensing catheter ablation improve procedural efficiency and efficacy compared to non-contact-force catheters in pediatric patients with AVNRT?
Population
Consecutive pediatric patients (< 18 years) who underwent AVNRT ablation
Comparison
Irrigated CF-sensing catheter (n = 130) vs non-CF catheter (n = 48)
Design
Retrospective study

May improve procedural safety in pediatric AVNRT ablation; leaves open whether CF-sensing catheters reduce conduction injury in randomized trials.

Does irrigated contact-force sensing catheter ablation improve procedural efficiency and efficacy compared to non-contact-force catheters in pediatric patients with AVNRT?
Absolute Event Rate: 100% vs 89.6%
p-value: p=0.001
In pediatric AVNRT ablation, irrigated contact-force sensing catheters improve procedural efficiency and acute success rates without increasing complications compared to conventional catheters.
Atlan et al. (2026) conducted a cohort in Atrioventricular nodal reentrant tachycardia (AVNRT) (n=178). Irrigated contact-force (CF) sensing catheter vs. Conventional non-contact-force (non-CF) catheter was evaluated on Acute procedural success (p=0.001). Irrigated contact-force guided RF ablation for pediatric AVNRT achieved 100% acute procedural success versus 89.6% with non-contact-force catheters (p=0.001), with shorter procedure times.
