In plain language
In 794 coronary procedures performed by three interventional cardiologists, each operator received about 0.06 mSv per procedure, and patient dose-area product related to operator dose at roughly 113:1, proposed as a rough marker for estimating operator dose.

What it found
The ratio between radiation exposure (dose-area product) and the dose finally absorbed by each operator was 113:1, proposed as a safety marker for estimating operator dose.
Key figures: 113:1 μGym2/mSv
Average operator dose per procedure was 0.06 mSv.
Key figures: 0.06 mSv per procedure
Total radiation exposure per angiographer across all procedure types was about 1.72 million μGym2 (median values).
Key figures: 1,724,557.5 μGym2 (median)
Elective CRA plus percutaneous coronary intervention (PCI) procedures accounted for the highest exposure per cardiologist, higher than diagnostic CRA or primary PCI.
Key figures: 833,371 μGym2 elective CRA+PCI vs 562,936 μGym2 CRA vs 328,250 μGym2 primary CRA+PCI
Limits to keep in mind
Only three interventional cardiologists at a single, unnamed centre; the abstract does not describe dosimeter placement, shielding used, or how absorbed dose was measured, and some units (e.g. 15,253) are unreported.
