Importance of a hydrophilic coronary wire in anatomically challenging transradial access: an extended case series.

Anatomic variations during transradial (TR) procedures are relatively common and represent a significant cause of technical failure, even for experienced radial operators. In this study, we present an interesting alternative technique to overcome these anatomical anomalies. A significant amount of TR procedures in various and challenging anatomical conditions were successfully completed with the use of a 0.014″ hydrophilic coronary guidewire.
