In plain language
In a randomized trial of 363 transradial coronary procedures, using 7.5 instead of 15 fluoroscopy frames per second cut operator dose measured at the thyroid collar by about 30% and also lowered patient dose.

What it found
Fluoroscopy at 7.5 frames/s compared with 15 frames/s was associated with a significant reduction in operator dose.
Key figures: 30% relative reduction
The authors conclude low rate fluoroscopy is a simple and effective method to reduce both operator and patient dose in transradial diagnostic angiography and percutaneous coronary intervention (PCI).
Trial included 363 transradial patients, 184 diagnostic angiography and 179 PCI, randomized before the procedure.
Key figures: 363 patients; 184 DCA, 179 PCI
Limits to keep in mind
Abstract is truncated, so patient dose and fluoroscopy time results and p-values are missing; operator dose measured with a single thyroid-collar dosimeter, and the setting appears to be a single centre with country not stated.
