![]() Conclusions: The use of a GuideLiner facilitates the approach to complex coronary interventions including chronic total occlusion and saphenous vein graft intervention by providing greater back-up support and easier engagement of coronary ostia. Procedural success was 98% in our series with no device-related periprocedural complications such as ostial dissection or myocardial necrosis. One patient had successful renal denervation with the aid of a GuideLiner catheter. Anomalous or angulated take-off of the treatment vessels (31%), previously deployed proximal stents (15%), heavy proximal calcification (9%) and tortuosity (7%) accounted for the remaining reasons. From September 2009 to October 2011, 54 consecutive patients underwent coronary intervention in our institution using a GuideLiner 21 out of 54 coronary applications were motivated by the need to increase support to cross CTOs, predominantly of the RCA. Patient demographics, lesion and vessel characteristics, procedural details and outcomes were prospectively entered into our database and analysed. Methods and results: Consecutive patients undergoing coronary or peripheral interventions where a GuideLiner was used were recruited into this study. We conducted a study on the feasibility and safety of utilising this catheter in a wider array of complex coronary interventions. The GuideLiner is a monorail catheter originally developed to facilitate delivery of stents to target lesions in tortuous vessels. The device effectively allowed stent delivery in challenging lesions, where conventional techniques have failed, without major complications.Īims: Challenging coronary anatomies including chronic total occlusions (CTO), extreme vessel tortuosity, diseased bypass grafts, and anomalous coronary arteries pose difficulties in coronary interventions. In this study, we presented a large registry of two centers used the GuideLiner catheter. None of the patients had coronary dissection or major complications. ![]() The mean depth of the GuideLiner catheter intubation was 30.3☒1.6 mm. 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. ![]()
