Abstract
Transradial catheterization and percutaneous coronary interventions have multiple advantages, including reduced bleeding risk, reduced length of stay and costs, and increased patient comfort. Transradial catheterization and interventions requires the acquisition of various additional skill sets including radial arterial puncture, the ability to navigate the upper extremity vasculature, and understanding catheter selection and coronary engagement technique. Although standard femoral catheter shapes perform adequately from the left or right radial approach for coronary angiography, for percutaneous coronary intervention guide catheter support is critical. This article summarizes some practical learning points pertaining to navigating the upper extremity vasculature, and understanding catheter selection and coronary engagement technique.
