In plain language
In 657 cardiac device implantations across nine centers, cardiac resynchronization therapy (CRT) procedures carried the highest patient dose, and newer customizable X-ray systems roughly tripled-down adjusted dose. Staff dose was measured but results are not given in the abstract.

What it found
Biventricular (CRT) device implantation had far higher fluoroscopy time and dose-area product (DAP) than dual chamber or ventricular device implantation.
Key figures: Median FT 837 s (IQR 480-1323) vs 117 s and 101 s; median DAP 1410 (IQR 807-2601) vs 150 and 129 cGy.cm²
During CRT, newer customizable X-ray systems gave lower adjusted DAP than four older systems.
Key figures: adjusted DAP 0.90 (IQR 0.26-1.01) vs 0.29 (IQR 0.23-0.39); P < .001
Dose reference levels for device implantation were proposed as third-quartile values from real-life data.
Fluoroscopy time during biventricular implantation was shorter than previously reported values.
Limits to keep in mind
Observational registry with abstract only; staff dosimeter results are not reported in the abstract, and system comparisons may be confounded by center practices.
