In plain language
At one children's hospital, adding 3D electroanatomic mapping to catheter ablation cut fluoroscopy time, with about a third of cases done with no fluoroscopy. Only patient dose was measured, though less fluoroscopy likely also lowers exposure for the electrophysiology (EP) team.

What it found
Mean fluoroscopy time fell after introduction of CARTO 3 electroanatomic mapping in normal heart, congenital heart disease and trans-septal groups.
Key figures: p < 0.01
Zero fluoroscopy was achieved in nearly a third of cases, and fluoroscopy time of 1 minute or less in almost half.
Key figures: 50/159 (31 %) zero fluoroscopy; 71/159 (45 %) ≤1 min
Fluoroscopy time decreased for accessory pathway and atrioventricular nodal reentrant tachycardia (AVNRT) ablations.
Key figures: p < 0.0001
After adjustment for age, weight and diagnosis, fluoroscopy time fell in all groups, and radiation dose and dose-area product (DAP) fell in the normal heart group.
Limits to keep in mind
Single-centre retrospective before-after comparison at a children's hospital; only patient radiation metrics were reported, so staff dose reduction is inferred rather than measured. Total sample size across periods not stated in the abstract.
