Contemporary Arterial Access in the Cardiac Catheterization Laboratory.

Obtaining femoral and radial arterial access in the cardiac catheterization laboratory using state-of-the-art techniques is essential to optimize outcomes, patient satisfaction, and procedural efficiency. Although transradial access is increasingly used for coronary angiography and percutaneous coronary intervention, femoral access remains necessary for numerous procedures, many requiring large-bore access, including complex high-risk coronary interventions, structural procedures, and procedures involving mechanical circulatory support. For femoral access, contemporary access techniques should combine the use of fluoroscopy, ultrasound, micropuncture needle, femoral angiography, and vascular closure devices, when feasible. For radial access, ultrasound may reveal important anatomic features and expedite access. Despite randomized controlled trials supporting use of routine ultrasound guidance for femoral and/or radial arterial access, ultrasound remains underused in cardiac catheterization laboratories. This article reviews contemporary techniques to achieve optimal arterial access in the cardiac catheterization laboratory.
