Is this trial a fit for you?
✓Likely a good fit
Adults indicated for invasive coronary angiography who meet inclusion criteria and do not have exclusion criteria such as STEMI, renal replacement therapy, severe radiocarpal joint deformities, or shock.
✕Probably not a fit
Patients with conditions that prevent distal radial access or who experience complications may not benefit.

What this trial studies
This interventional study compares ultrasound-guided distal radial artery access in the anatomical snuffbox with conventional radial access for invasive coronary angiography. The goal is to determine whether distal access lowers crossover to another vascular route. It references existing guidelines that favor transradial access and notes potential benefits of distal radial access, including reduced radial artery occlusion. The study focuses on whether the distal approach affects procedural continuity and safety.
Why it matters
Potential benefit: If successful, patients may experience fewer procedure interruptions and preserved forearm blood flow, potentially improving recovery times.
How similar studies have gone: Prior studies have suggested benefits of distal radial access, including reduced radial artery occlusion, but crossover outcomes remain less clear.
