In plain language
In 76 children undergoing catheter ablation with 3D mapping at one center, fluoroscopy was used in only 18% of cases, averaging about 5 minutes, with high success. Staff dose was not measured, but less fluoroscopy implies less exposure for the electrophysiology (EP) team.

What it found
Fluoroscopy was needed in only a minority of pediatric ablation substrates using 3D electroanatomic mapping.
Key figures: 14 (18.4%) of 78 substrates
When fluoroscopy was used, mean duration was short.
Key figures: 5.4±3.15 min
Right-sided arrhythmia substrates, including all atrioventricular nodal reentrant tachycardia (AVNRT), were ablated with zero fluoroscopy.
High acute success and low recurrence were achieved.
Key figures: 97.4% (76/78) acute success; 5.1% (4/78) recurrence
Only two minor complications occurred, both resolving.
Key figures: 2 complications
Limits to keep in mind
Single-center retrospective series of 76 patients with one operator, no comparison group and short follow-up; staff radiation dose was not measured.
