Radial access has largely substituted femoral access for coronary interventions. Nevertheless, the femoral artery remains indispensable for gaining access to structural and complex percutaneous coronary interventions such as transcatheter aortic valve implantation and chronic total occlusion interventions, respectively. Ultrasound-guided femoral puncture is a broadly available, inexpensive, and relatively easy-to-learn technique. According to the existing evidence, ultrasound guidance for gaining femoral access has improved the effectiveness and safety of the technique. In the present paper, we sought to review the current literature in order to provide the reader with up-to-date data regarding the benefits of ultrasound-guided femoral access compared with the conventional technique as well as describing the state-of-the-art technique for gaining femoral access under ultrasound guidance.
