In plain language
In 443 atrial fibrillation ablations, remote magnetic navigation cut fluoroscopy time compared with manual catheters, more so with experience, but lengthened procedures. Staff dose was not measured, so reduced exposure for electrophysiologists and the fluoroscopy team is inferred, not shown.

What it found
Fluoroscopy time was shorter with remote magnetic navigation than with manual ablation across the whole cohort.
Key figures: 53.5±30.1 vs 68.1±27.6 min; p<0.001
In the most recent 50 procedures per group, after the learning curve, the fluoroscopy time difference was larger.
Key figures: 35.4±13.9 vs 61.2±32.6 min; p<0.001
Total procedure time was longer with remote magnetic navigation.
Key figures: 276.9±75.0 vs 208.3±61.6 min; p<0.001
Acute success and complication rates were similar between approaches.
Key figures: success 98.6% vs 95.6%, p=0.065; complications 2.3% vs 4.8%, p=0.16
Staff radiation dose was not measured; air kerma and dose-area product were not collected, so operator benefit is inferred rather than measured.
Limits to keep in mind
Single-centre, non-randomized retrospective comparison with heterogeneous operators and learning-curve effects. Only fluoroscopy time was recorded; no patient or staff dose metrics or personal dosimetry were collected.
