Brief Summary
Coronary angiography is performed to evaluate for obstructive coronary artery disease. This is commonly performed via the transfemoral or transradial approach with the latter increasing in frequency. One of the most common complications of transradial access is radial artery occlusion occurring in \~5% of patients which prohibits the use of the radial artery in the future. There is evidence to support the use of intraprocedural anticoagulation to mitigate the risk of radial artery occlusion however the role of post-procedural anticoagulation has not been previously evaluated. Rivaroxaban is a direct oral anticoagulant (DOAC) with a safety profile superior to that of vitamin K antagonists. Given the safety profile, ease of use, and feasibility of DOAC therapy, our study will endeavor to evaluate the use of rivaroxaban 15mg orally once daily for 7 days after transradial access and the impact this has on the rate of radial artery occlusion.
