Key result
Irrigated-tip ablation with 3D mapping linked to ~68% lower 4-year right-sided AP recurrence vs conventional methods.
Why the study?
Catheter ablation of right-sided accessory pathways in patients under 18 years has lower success and higher recurrence rates, and data on irrigated-tip catheter use in this group are scarce.
Does an irrigated-tip catheter approach with 3-D mapping reduce recurrence of right-sided accessory pathways in adolescents compared to a conventional non-ITC approach?

Absolute Event Rate: 94% vs 81%
p-value: p=0.04
In adolescents with right-sided accessory pathways, irrigated-tip catheter ablation with 3-D mapping significantly reduces recurrence rates compared to conventional ablation without compromising safety.

May support irrigated-tip ablation with 3-D mapping in adolescents; leaves open confirmation in randomized trials.
Telishevska et al. (2017) conducted a cohort in Right-sided accessory pathways (n=105). Irrigated-tip catheter (ITC) approach with 3-D mapping vs. Conventional non-ITC approach was evaluated on Freedom from AP recurrence at 4 years (p=0.04). Irrigated-tip catheter ablation with 3-D mapping for right-sided accessory pathways in adolescents yielded higher 4-year freedom from recurrence than a conventional approach (94% vs 81%; P=0.04).
