Using Large Bore Catheters via the Radial Approach

By Paul Williams

Transradial access for coronary intervention is rapidly increasing in popularity worldwide but, despite the many advantages of this approach, the small calibre of the radial artery is considered by some to be a major limitation to performing complex PCI requiring large bore (> 6 French) guide catheters. However many radial arteries will readily accept a 7 French (Fr) sheath and the introduction of newer technologies such as 7.5 Fr sheathless guide catheters (with an external diameter smaller than a 6 French sheath) may allow even these complex cases to be performed routinely via a transradial approach.

In this study 55 true coronary bifurcation lesions were scheduled to be treated using conventional crush stenting using 7 French sheaths via the transradial approach. Successful transradial crush stenting was performed in 93% patients and successful transradial 2-stent bifurcation PCI was performed in 96% patients. There were no procedural or in-hospital complications.

This study demonstrates that complex PCI requiring large bore catheters can be performed successfully in a very high proportion of patients via the transradial approach. As there is an increased risk of femoral vascular complications with large sheaths, the radial artery may represent the preferable vascular access site for patients undergoing complex PCI requiring large bore guide catheters.
