Abstract:
Coronary stent delivery can be extremely challenging in tortuous and calcified lesions especially when radial approach is chosen. Guide extension catheter is a useful tool for overcoming the inherent difficulties arising by the use of radial access in complex percutaneous interventions. We describe a technique for guide extension catheter system advancement by presenting two cases. This was performed stepwise by repeated distal balloon anchoring in the coronary artery of interest.
