STENT USING A GUIDELINER SERIES

The GuideLiner catheter was mainly used to increase back-up of the guide catheter (85.9%), and in 95.3% of all cases, the procedure was successful. Lesions were mostly (90.6%) class B2 or C according to the AHA/ACC lesion classification. Femoral approach was employed in all cases. The mean age of the patients was 69.8☑0.0 years. Descriptive statistics and frequencies were used in statistical analyses. The data were assessed in terms of the lesion characteristics, procedural success, and complications. We retrospectively collected the coronary angiography records of 64 patients between Januand Augin whom conventional techniques failed for stent delivery and 5-in-6 Fr GuideLiner catheter was used for this purpose.

In this study, we aimed to present one of the largest series of experience with GuideLiner catheter utilized for challenging percutaneous coronary interventions in two centers. GuideLiner catheter provides adequate back-up support and a coaxial guide engagement for stent delivery in complex coronary anatomies. Moreover, the aim of this article is to help interventional cardiologists using the device in difficult lesions to avoid potential complications. 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. 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. 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. Recently, a new support rapid exchange catheter, the Guideliner, has been designed specifically for device delivery.įrom 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. Stent delivery in complex coronary anatomy with severe calcification and tortuosity is still a common cause of percutaneous coronary interventions (PCI) failure.
