We describe here our experience with the Guideliner catheter for stent delivery and backup support we discuss its utility and drawbacks in acute and stable clinical settings.
Conclusions: In our experience, the Guideliner catheter is safe to use and helps device delivery in difficult settings. In 2 cases, we had stent damage due to the passage of the stent through the Guideliner metal collar. Three proximal dissections were detected and sealed with stent implantation. The other 9 cases were performed successfully. Results: One case, the first one, failed, as stent could not be delivered to the target lesion. In 2 cases PTCA with drug‐eluting balloon was performed in the other cases second‐generation drug‐eluting stent was implanted. In 3 cases the operator chose the femoral access, in 2 cases crossover from radial to femoral access was needed, and the other cases were performed radially.
Methods: From June 2010 to December 2010, we performed 10 cases using the Guideliner catheter to improve backup support and facilitate stent delivery: 2 emergent PCI for ST elevation myocardial infarction, and 8 stable elective PCI. Recently, a new support rapid exchange catheter, the Guideliner, has been designed specifically for device delivery. Introduction: Stent delivery in complex coronary anatomy with severe calcification and tortuosity is still a common cause of percutaneous coronary interventions (PCI) failure.
