Insights
The GuideLiner catheter effectively facilitated stent delivery in complex coronary anatomies when standard methods failed. This large two-center study found the device safe and successful for challenging percutaneous coronary interventions.
Area of Science:
- Interventional Cardiology
- Medical Devices
- Coronary Artery Disease
Background:
- Complex coronary anatomies pose challenges for stent delivery.
- Conventional techniques may fail in difficult cases.
- The GuideLiner catheter offers enhanced support for stent placement.
Purpose of the Study:
- To evaluate the efficacy and safety of the GuideLiner catheter.
- To present experience with GuideLiner catheter in challenging percutaneous coronary interventions.
- To assess procedural success and complications in a large patient series.
Main Methods:
- Retrospective analysis of 64 patients undergoing percutaneous coronary intervention.
- Use of 5-in-6 Fr GuideLiner catheter when conventional stent delivery failed.
- Assessment of lesion characteristics, procedural success, and complications.
Main Results:
- Successful stent delivery in 95.3% of cases.
- GuideLiner catheter primarily used for increased guide catheter back-up (85.9%).
- No coronary dissections or major complications reported.
Conclusions:
- The GuideLiner catheter is effective for stent delivery in challenging coronary lesions.
- It provides a safe alternative when conventional methods fail.
- This study supports its utility in complex percutaneous coronary interventions.
Objective:
GuideLiner catheter provides adequate back-up support and a coaxial guide engagement for stent delivery in complex coronary anatomies. 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.
Methods:
We retrospectively collected the coronary angiography records of 64 patients between January 1, 2012 and August 1, 2014 in whom conventional techniques failed for stent delivery and 5-in-6 Fr GuideLiner catheter was used for this purpose. The data were assessed in terms of the lesion characteristics, procedural success, and complications. Descriptive statistics and frequencies were used in statistical analyses.
Results:
The mean age of the patients was 69.8±10.0 years. Femoral approach was employed in all cases. Lesions were mostly (90.6%) class B2 or C according to the AHA/ACC lesion classification. 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. The mean depth of the GuideLiner catheter intubation was 30.3±21.6 mm. None of the patients had coronary dissection or major complications.
Conclusion:
In this study, we presented a large registry of two centers used the GuideLiner catheter. The device effectively allowed stent delivery in challenging lesions, where conventional techniques have failed, without major complications.
