摘要: Aims: The aim of the study was to determine safety, efficacy and feasibility a new chronic total occlusion (CTO) device using optical coherence tomography (OCT) technology, Ocelot catheter (Avinger, Inc., Redwood City, CA, USA), for crossing SFA CTOs following guidewire failure.Methods results: Prospective, multicentre, market preference testing. Thirty-three patients with confirmed CTO (99-100% stenosis by visual estimate) their superficial femoral artery (SFA) were treated between September 28, 2011, December 9, at three European centres. crossed 94% (31/33) CTOs, allowing placement in distal true lumen. All (100%) lesions without any major adverse safety events. Procedural time contrast dose significantly reduced (p<0.0001) when compared similar, non-OCT-guided (Wildcat catheter; Avinger, Inc.). Overall physician feedback on performance positive an 87% average rating excellent or good across seven categories. Performance ratings Ocelot's OCT imaging guidance consistently 86% five categories.Conclusions: combines advanced technology real-time guidance. When similar catheter, profile improved. Total procedure volumes reduced. is safe, efficient effective tool CTOs.
