Millions of percutaneous coronary interventions (PCIs) are performed each year around the world to treat obstructive coronary artery disease. In order to access the arteries, interventional cardiologists traditionally use the femoral artery, which is still the most common access route for PCI in the United States. However, access via the radial artery is increasingly common. The transradial approach for PCI was developed 23 years ago and is used in more than 50 percent of procedures in most European countries.
