Editorial Comment:Transradial approach: Do we have gain without excessive pain?

Transradial approach (TRA) was described over 60 years back, but it was not gained much attention due to equipment and technical limitations (1). Then it received new interest after the work of Campeau et al. (2) some 25 years back. After him, Kiemeneij et al. (3) introduced successful interventional procedures via radial approach. Since then, TRA has become popular in many parts of the world and many centers across the world has been adopting and developing transradial catheterization training programmes (4, 5).
