Transradial artery access (TRA) for diagnostic CA or percutaneous coronary intervention (PCI) is associated with lower bleeding and vascular complications than transfemoral artery access (TFA). The European Society of Cardiology guidelines and American Heart Association support a TRA first strategy and evidence also supports an improvement in healthcare quality, and reduced cost. While TFA predominates peripheral interventions, increases in dedicated equipment and the technical expertise may result in TRA as a preferred access in this patient group as well.
