- INTERVENTIONAL
- Study Design
- PARALLEL
- Primary Outcome Measures
Name Time Method Bleeding events Day 1 Will be bleeding events according to Bleeding Academic Research Consortium (BARC) criteria.
Occurrence of postprocedural RAO Day 1 Will be the occurrence of postprocedural RAO assessed with high-resolution vascular ultrasound. Experienced sonographers will perform color Doppler ultrasound in all study patients after removal of the compression device to examine the radial, ulnar, and brachial arteries of the access forearm.
- Secondary Outcome Measures
Name Time Method Sonographic characteristics of radial artery occlusion 3 Month Occlusion lengths or minimal residual perfusion
