Radiation safety and vascular access: attitudes among cardiologists worldwide

•We examined radiation safety and arterial access practices among 1000 cardiologists.•Radial access is perceived as having higher radiation dose compared to femoral access.•Right radial access is performed more frequently than left radial access.•US operators use less radiation protection that non-US operators.•Only 2/3 of interventionalists are mandated to undergo radiation safety training.

ObjectivesTo determine opinions and perceptions of interventional cardiologists on the topic of radiation and vascular access choice.BackgroundTransradial approach for cardiac catheterization has been increasing in popularity worldwide. There is evidence that transradial access (TRA) may be associated with increasing radiation doses compared to transfemoral access (TFA).MethodsWe distributed a questionnaire to collect opinions of interventional cardiologists around the world.ResultsInterventional cardiologists (n = 5332) were contacted by email to complete an on-line survey from September to October 2013. The response rate was 20% (n = 1084). TRA was used in 54% of percutaneous coronary interventions (PCIs). Most TRAs (80%) were performed with right radial access (RRA). Interventionalists perceived that TRA was associated with higher radiation exposure compared to TFA and that RRA was associated with higher radiation exposure that left radial access (LRA). Older interventionalists were more likely to use radiation protection equipment and those who underwent radiation safety training gave more importance to ALARA (as low as reasonably achievable). Nearly half the respondents stated they would perform more TRA if the radiation exposure was similar to TFA. While interventionalists in the United States placed less importance to certain radiation protective equipment, European operators were more concerned with physician and patient radiation.ConclusionsInterventionalists worldwide reported higher perceived radiation doses with TRA compared to TFA and RRA compared to LRA. Efforts should be directed toward encouraging consistent radiation safety training. Major investment and application of novel radiation protection tools and radiation dose reduction strategies should be pursued.
