Fluoroscopy time was registered in 87.5% (42/48) of centers and in 83.1% of procedures (median, 3.7 min, IQR, 2.3–6.3 for CA; 10.3 min, 6.7–16.2 for PCI). Variability across centers was high. Old equipment and routine left ventriculography were more common and number of registered frames and frame rate were higher in centers delivering high doses. The radial route was associated with lower doses than the femoral route (median KAP 26.8 Gy·cm<sup>2</sup> [15.1–44.25] vs. 28.1 [16.4–46.9] for CA, respectively; and 55.6 Gy·cm<sup>2</sup> [32.2–92.1] vs. 59.4 [24.6–99.9] for PCI, respectively; <italic>P</italic> < 0.01).</p> </sec> <sec id="ccd25327-sec-0005" sec-type="section"> <title>Conclusions</title> <p>This survey showed a very high rate of compliance with dose registration during CA and PCI in French nonacademic hospitals.
