In plain language
This EHRA review reports that ultra low-dose fluoroscopy settings, collimation, low frame rates, shielding and 3D mapping or intracardiac echo can greatly reduce radiation in electrophysiology procedures, lowering exposure for patients and the electrophysiology (EP) team without reported loss of safety or efficacy.

What it found
Ultra low-dose fluoroscopy protocols markedly reduce dose in complex ablation without worsening procedure times, outcomes or complications.
Key figures: 30-fold reduction of dose-area product (DAP)
Typical lifetime occupational exposure for cath lab operators carries a meaningful attributable cancer risk.
Key figures: 50-200 mSv; excess cancer risk 1 in 100
Reducing frame rate substantially lowers radiation dose; cine mode delivers roughly 10 times the dose of fluoroscopy.
Key figures: six- to eight-fold reduction (25 to 3.75 fps); ~10-fold higher in cine
Lead mattress reduces scatter; suspended protection systems or cabins reduce exposure to near background and relieve orthopaedic load, while lead gloves offer limited reduction.
Key figures: up to 70% (mattress); 10-30% (gloves)
Radiation awareness was lacking in many centres according to an EHRA survey.
Key figures: >25% used ≥12 fps; >40% did not or only occasionally used collimation
Limits to keep in mind
Narrative expert review without systematic search; cited dose studies were selected for reduction interventions and may not reflect real-life practice, and most data concern patient dose metrics rather than measured staff dose or health outcomes.
