In plain language
In 452 cardiac catheterization and percutaneous coronary intervention (PCI) patients, low frame-rate fluoroscopy was associated with about 85% lower patient air kerma and dose-area product (DAP) without longer fluoroscopy time. Staff dose was not measured, though lower patient dose generally means less scatter for the fluoroscopy team.

What it found
Low-dose frame rates (≤7.5 f/s) were associated with substantially lower air kerma than standard-dose (≥10 f/s).
Key figures: 100.70 mGy [interquartile range (IQR), 46.42-233.35 mGy] vs 660.96 mGy [IQR, 362.78-1373.65 mGy]; P<.001
Dose area product was lower with low-dose settings.
Key figures: 723.60 μGy•m² [IQR, 313.09-2328.22 μGy•m²] vs 5203.40 μGy•m² [IQR, 2743.55-10064.71 μGy•m²]; P<.001
Fluoroscopy time did not differ between groups.
Key figures: 13.33 min vs 12.75 min; P=.95
Contrast use was slightly lower with low-dose settings.
Key figures: 100 mL vs 115 mL; P<.03
No low-dose procedures required conversion to standard dose.
Limits to keep in mind
Single observational, non-randomized comparison with unequal groups and possible case-mix differences; only patient dose metrics were measured, not staff dose or clinical outcomes.
