An Update on Radial Artery Access and Best Practices for Transradial Coronary Angiography and Intervention in Acute Coronary Syndrome: A Scientific Statement From the American Heart Association

Circ Cardiovasc Interv. 2018 Sep;11(9):e000035. doi: 10.1161/HCV.0000000000000035.


Transradial artery access for percutaneous coronary intervention is associated with lower bleeding and vascular complications than transfemoral artery access, especially in patients with acute coronary syndromes. A growing body of evidence supports adoption of transradial artery access to improve acute coronary syndrome-related outcomes, to improve healthcare quality, and to reduce cost. The purpose of this scientific statement is to propose and support a "radial-first" strategy in the United States for patients with acute coronary syndromes. This document also provides an update to previously published statements on transradial artery access technique and best practices, particularly as they relate to the management of patients with acute coronary syndromes.
