About this study
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.
Read the detailed description
Assessment of the coronary artery anatomy is commonly performed by coronary angiography (CA), which is the gold standard for evaluation of obstructive coronary artery disease (CAD). Coronary revascularization, opening of obstructed vessels, is most commonly performed by percutaneous coronary intervention (PCI) in patients with obstructive CAD. Traditionally, PCI is performed with implantation of one or more permanent metallic stents which act as a scaffold for arterial recoil and, in the case of drug eluting stents (DES), provide a platform for delivery of anti-proliferative agents. The transradial access (TRA) has rapidly emerged as the preferred vascular access site for CA and PCI with more than 50% of all coronary angiograms being performed via this approach.
There are several advantages to TRA for angiography including rapid hemostasis, early ambulation after the procedure thereby improving patient comfort and experience, and a decrease in the length of hospital stay. There is also a reported reduction in all-cause mortality, major adverse cardiovascular events, major bleeding, and vascular complications with TRA as compared to transfemoral access. However, radial artery occlusion (RAO) remains an important complication of this procedure as it precludes the reuse of this artery for future transradial approaches as well as the use of the vessel as a conduit for coronary artery bypass grafting.
Reports of RAO post-TRA has varied in the literature from ~4-10% in observational and randomized trials. In the largest systematic review published to date, the overall rate of RAO was 5.2% amongst the 46,631 subjects across 92 studies between 1989 and 2016. This systematic review also noted that the rate of early (i.e. <7 days) vs. late (i.e. >7 days) RAO was significantly higher which is suggestive of late recanalization in some patients. The factors which affect recanalization are not clear however standard of care involves administration of heparin during the procedure and patent hemostasis following the procedure. Patent hemostasis is performed by applying a delicate balance of pressure to prevent bleeding but not to the point of completely occlude the blood vessel and cessation of blood flow distally.
Numerous trials have explored the role of anticoagulation during angiography to reduce RAO and a recently published systematic review and meta-analysis demonstrated more intensive anticoagulation is protective. Indeed, this remains an active area of research with numerous ongoing trials evaluating the effect of intensive or higher dose anticoagulation during the procedure for prevention of RAO. Additionally, there were higher rates of RAO with diagnostic angiography as opposed to PCI purportedly as the latter involves higher doses of anticoagulation.
Direct oral anticoagulant (DOAC) therapy has provided a safer alternative with an improved bleeding profile over vitamin K antagonist anticoagulation therapy. The use of DOACs in cardiovascular medicine ranges from various conditions including stroke prevention in atrial fibrillation7-12 to venous thromboembolism13-16 to stable cardiovascular disease.
While intraprocedural anticoagulation has been studied extensively, a course of anticoagulation therapy post-TRA has not been studied. 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 RAO. Should this study prove to be positive, this could impact our routine standard of care with respect to having a strategy which could reduce the rate of this complication thereby preserving the radial artery for future access and/or as a conduit for coronary artery bypass grafting.

Detailed description
Assessment of the coronary artery anatomy is commonly performed by coronary angiography (CA), which is the gold standard for evaluation of obstructive coronary artery disease (CAD). Coronary revascularization, opening of obstructed vessels, is most commonly performed by percutaneous coronary intervention (PCI) in patients with obstructive CAD. Traditionally, PCI is performed with implantation of one or more permanent metallic stents which act as a scaffold for arterial recoil and, in the case of drug eluting stents (DES), provide a platform for delivery of anti-proliferative agents. The transradial access (TRA) has rapidly emerged as the preferred vascular access site for CA and PCI with more than 50% of all coronary angiograms being performed via this approach.
There are several advantages to TRA for angiography including rapid hemostasis, early ambulation after the procedure thereby improving patient comfort and experience, and a decrease in the length of hospital stay. There is also a reported reduction in all-cause mortality, major adverse cardiovascular events, major bleeding, and vascular complications with TRA as compared to transfemoral access. However, radial artery occlusion (RAO) remains an important complication of this procedure as it precludes the reuse of this artery for future transradial approaches as well as the use of the vessel as a conduit for coronary artery bypass grafting.
Reports of RAO post-TRA has varied in the literature from ~4-10% in observational and randomized trials. In the largest systematic review published to date, the overall rate of RAO was 5.2% amongst the 46,631 subjects across 92 studies between 1989 and 2016.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 5 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Canada, United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Assessment for futility). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Primary efficacy outcome - rate of radial artery occlusion (time frame: 30 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03630055, which also lists 18 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2026.
