In plain language
In 206 patients having atrial fibrillation ablation, tighter collimation, a lower frame rate, shorter angiography runs and greater reliance on 3D mapping cut dose-area product by about 90%, with similar success but longer procedures. Staff dose was not measured directly.

What it found
A low-dose fluoroscopy protocol cut mean dose-area product by about 90%.
Key figures: 8,690 ± 5,727 to 837 ± 647 cGycm(2)
Mean fluoroscopy time was significantly reduced with the low-dose protocol.
Key figures: 29.9 ± 11.3 min vs 13.3 ± 8.3 min
Pulmonary vein isolation success was maintained with the low-dose protocol.
Key figures: 97% (98/101) vs 100%
Procedure time was longer with the low-dose protocol.
Key figures: 160.9 ± 35.7 vs. 138.1 ± 34.3 min
Limits to keep in mind
Non-randomized controlled comparison at what appears to be a single centre; only patient dose metrics (DAP, fluoroscopy time) were measured, not staff dose.
