In plain language
In 157 ablation patients at two centres, a near-zero fluoroscopy approach using 3-D mapping cut dose area product by about 90% for operators from beginner to expert, without longer procedures or more complications. Staff dose was not measured directly.

What it found
Dose area product fell by about 90% soon after a near-zero fluoroscopy approach using 3-D mapping was introduced, including among operators in training.
Key figures: 90% reduction of DPA
All four operators, from beginner to expert, had significantly lower dose area product than the historical fluoroscopy-guided control group.
Key figures: control 637 ± 611 μGy/m2; beginner 44.1 ± 79.5 μGy/m2, p = 0.002; 1st year fellow 24.3 ± 46.4.5 μGy/m2, p = 0.001; 2nd year fellow 130.3 ± 233.3 μGy/m2, p = 0.003; expert 9.3 ± 37.4 μGy/m2, P < 0.001
Procedure duration, acute success and complications did not differ significantly between the near-zero fluoroscopy and control groups.
The comparison was 100 fluoroscopy-guided procedures against 57 near-zero fluoroscopy procedures across two centres.
Key figures: 157 patients; 100 control, 57 near-zero fluoroscopy
Limits to keep in mind
Small non-randomized study comparing against a historical control, with only four operators and 57 intervention procedures. Only patient dose area product was measured; staff doses were not directly measured.
