Current State of Radial Artery Catheterization in ST-Elevation Myocardial Infarction

A well-established body of evidence demonstrating the advantages of a transradial approach for coronary angiography and intervention has led to worldwide adoption of this technique. In some countries, radial access has replaced femoral access as the dominant access site for percutaneous coronary intervention (PCI). More recently, numerous randomized controlled trials have compared transradial and transfemoral access in patients with ST elevation myocardial infarction (STEMI) and have shown that transradial access is associated with lower mortality and less major bleeding. This review examines the advantages of transradial primary PCI for STEMI patients, addresses concerns in adopting this approach for primary PCI, and reviews recommendations on how to start a transradial primary PCI program.
