Radial loop: Can straightening of the loop push the guiding catheter? Do we need to be more watchful? A case report and literature review

Abstract

Radial loops are the most common radial anatomical entity for deferring or failure of transradial approach. Complex loops may not straighten immediately after traversing the loop and may take a few minutes to straighten out. Here, we describe a case of a complex radial artery loop encountered during transradial percutaneous coronary intervention. We furthermore present a literature review and outline tips and techniques to successfully traverse the radial loop.
