Reported studies have been small in number and complications' rates varied significantly according to the Guideliner version and the chosen access route. ► The use of a Guideliner facilitates complex coronary intervention. What is already known about this subject? The change in design of the V2 Guideliner was a likely contributor but the Further analysis of 124 cases of V3 Guideliner use demonstrated no cases with proximal collar-stent interactions, one case of longitudinal stent deformation and two incidents of stent interaction with the distal edge of the V3 Guideliner.Ĭonclusions: We have demonstrated a higher incidence of V2 Guideliner complications compared to previous series. Anatomical data suggest that extending the V2 Guideliner tubing sited the proximal collar of the device in the brachiocephalic/subclavian artery, a potential site of tortuosity and potential cause of the Guideliner proximal collar-stent interaction. Proximal collar interaction and stent damage occurred in 19 cases (10%). One major complication was reported (coronary dissection). Results: Total of 188 cases of V2 Guideliner use were identified. Further analysis of consecutive cases employing V3 Gudieliner took place and the incidence of complications were compared between V2 and V3 groups. To understand the potential anatomical mechanism of these complications, analysis of normal great vessel anatomy was undertaken in separate cohort of patients undergoing cardiac catheterisation via right radial approach. Complications were identified, analysed and classified into major versus minor ones. Methods: Retrospective analysis of consecutive cases employing V2 Guideliner from two university teaching hospitals.
