Post-procedural upper extremity dysfunction (UED) remains one of the few potential questions about the overall benefits of the transradial approach (TRA) to endovascular procedures compared to femoral (TFA). Data on UED is limited, but the most comprehensive study curiously shows similar incidence of post-procedural UED with TFA as TRA. The effects of trAnsRadial perCUtaneouS coronary intervention on upper extremity function (ARCUS) study will investigate whether patient characteristics influence radial access outcomes such as UED. ARCUS may herald a post-radial-adoption era of more detailed strategies for radial access optimization, typical of a maturing technology.
