Strategies to Maintain Radial Artery Patency Following Diagnostic Coronary Angiography - Subgroup of Patients on Oral Anticoagulants

Strategies to Maintain Radial Artery Patency Following Diagnostic Coronary Angiography - Subgroup of Patients on Oral Anticoagulants

To investigate whether omitting systemic anticoagulation during transradial coronary angiography and/or a distal radial access reduce the risk of postprocedural radial artery occlusion

Inclusion Criteria:

• Clinical indication to perform diagnostic coronary angiography
• Pretreatment with oral anticoagulants (phenprocoumon or direct oral anticoagulants [dabigatran, apixaban, rivaroxaban, or edoxaban])
• Age > 18 years
• Written informed consent

Exclusion Criteria:

• Already administered additional anticoagulation prior to coronary angiography
• Planned coronary intervention
• Preexisting radial artery occlusion or missing pulse at the potential puncture sites
• Allergy / intolerance to anticoagulants
• Active bleeding or comorbidity with elevated bleeding risk
• Pregnancy
• Inability to sign informed consent
• Participation in another trial
