Roadmap for the radial: Should we stop for directions?

Regimented use of radial artery angiography prior to ST-segment myocardial infarction (STEMI) intervention may improve complication rates and can be associated with improved procedural success, procedural time, and reduction in access-site bleeding. Routine radial artery angiography may improve procedural quality without increase in procedural time or contrast use. Regardless of whether universal or selective radial angiography is best practice, angiography is an important tool to use for efficient radial access.
