Clinical Trial Summary

Transradial access (TRA) is the preferred vascular access site for invasive coronary angiography. TRA is limited by blockage of the radial artery post-procedurally, preventing future use of TRA. This is referred to as radial artery occlusion (RAO) and occurs in ~5% of cases. While intraprocedural anticoagulation has been studied extensively to mitigate this complication, oral anticoagulation post-TRA has not. The investigators will assess the impact of a one-week course of rivaroxaban post-TRA to reduce the rate of ultrasound-defined RAO at 30 days.
