In plain language
In a small nonrandomized series of 19 catheterization cases, operators working inside a complete shielding enclosure had no measurable significant radiation exposure, while those using standard shielding were exposed in all body regions. Health outcomes and other team members were not studied.

What it found
Operators using the Trinity system had no measurable significant radiation exposure in any body region or for the whole case.
Operators using standard shielding alone were exposed in all body regions, and total per-case exposure differed significantly from the Trinity system.
Key figures: P < 0.0001
The system combines fixed shields, radiation drapes and flexible radiation-resistant materials while keeping full patient contact and equipment control, with the aim of removing the need for lead aprons.
Limits to keep in mind
Small, nonrandomized first-in-man series of 19 cases with exposure to operators only. Dose values, other staff exposure and ergonomic outcomes are not reported in the abstract, and the claim of eliminating aprons was not tested directly.
