In plain language
In 584 pacemaker and defibrillator implantations at one hospital, a low-frame-rate, optimized-settings protocol was associated with 64% lower patient dose-area product without longer procedures or more complications. Staff dose was not measured, though lower patient dose usually means less scatter.

What it found
Introducing the dose reduction protocol was associated with a 64% reduction in dose-area product for CIED implantations.
Key figures: 64% reduction; 1372 ± 2659 vs. 3792 ± 5025 cGcm2, P < 0.001
Fluoroscopy time and procedure time did not increase after the protocol was introduced.
Key figures: fluoroscopy 13 ± 15 vs. 13 ± 15 min; procedure 93 ± 52 vs. 92 ± 52 min
Complication rates did not differ significantly between before and after groups.
The protocol used reduced frame rates plus optimized image processing and exposure settings.
Key figures: 4 FPS fluoroscopy, 7.5 FPS cine
Limits to keep in mind
Single-centre retrospective before-after chart review measuring patient dose-area product only; staff dose was not measured. Abstract only, with limited detail on how complications were assessed.
