Radial versus femoral access for coronary angiography and intervention is associated with lower patient radiation exposure in high-radial-volume centres: Insights from the RAY'ACT-1 study.

Background: Literature suggests that radial access is associated with higher radiation doses than femoral access.

Aims: To compare patient radiation exposure during coronary angiography (CA) and percutaneous coronary intervention (PCI) with radial versus femoral access.

Methods: RAY'ACT is a nationwide, multicentre, French survey evaluating patient radiation in interventional cardiology.
