Radial anomalies in the transradial access in percutaneous coronary intervention: characteristics and results of 7 years experience

Previous studies have demonstrated the feasibility and safety of using the radial artery as an access path for coronary angiography (CA). In fact, some centers use this as routine access in both diagnostic and interventional coronary procedures. Anatomic variations of the radial have been related to failure of transradial approach in the setting of percutaneous coronary intervention (PCI). The purpose of our study was to assess the rate and features of radial anatomic variations and its influence on the outcome of PCI.
