Optimizing Transradial Access: Radiation, Contrast, Access Site Crossover, and Ergonomics.

This article summarizes the data comparing radiation exposure and contrast use between transradial and transfemoral cardiac catheterizations. It also reviews the important features that may predict access site failure and crossover. In addition, it reviews the concept of ergonomics in the catheterization laboratory and how clinicians can improve the transradial approach.
