In plain language
In 124 patients undergoing atrial flutter ablation, using non-fluoroscopic navigation roughly halved fluoroscopy time and dose-area product without lengthening procedures. Staff dose was not measured, but less fluoroscopy likely means less exposure for the electrophysiology team.

What it found
Non-fluoroscopic navigation shortened fluoroscopy time during cavotricuspid isthmus ablation.
Key figures: 9.4 vs 16.7 min, P < 0.05
Dose-area product was roughly halved with non-fluoroscopic navigation.
Key figures: 2,128.3 vs 4,129.9 μGy*m2, P < 0.05
Total radiofrequency time was shorter with non-fluoroscopic navigation.
Key figures: 1,870.5 vs 2,335.5 sec, P < 0.05
Procedure duration and recurrence did not differ significantly between groups.
Key figures: 169.6 vs 157.6 min; recurrences 6.5 vs 11.3%
Acute success was high overall.
Key figures: 122 patients (98.4%)
Limits to keep in mind
Retrospective, single-series comparison of 124 patients without randomization; only patient-level exposure metrics (fluoroscopy time, dose-area product (DAP)) were reported, with no staff dosimetry. Country and centre not stated in the abstract.
