Theory and practical based approach to chronic total occlusions.
Coronary chronic total occlusions (CTOs) represent the most technically challenging lesion subset that interventional cardiologists face. CTOs are identified in up to one third of patients referred for coronary angiography and remain seriously undertreated with percutaneous techniques. The complexity of these procedures and the suboptimal success rates over a long period of time, along with the...
متن کاملThe Hybrid Approach to Intervention of Chronic Total Occlusions
The "hybrid" approach to chronic total occlusion (CTO) percutaneous coronary intervention (PCI) was developed to provide guidance on optimal crossing strategy selection. Dual angiography remains the cornerstone of clinical decision making in CTO PCI. Four angiographic parameters are assessed: (a) morphology of the proximal cap (clear-cut or ambiguous); (b) occlusion length; (c) distal vessel si...
متن کاملA novel approach to chronic total occlusions: the crosser system.
OBJECTIVES To evaluate safety and efficacy of the CROSSER CTO Recanalization System (CROSSER). BACKGROUND The CROSSER, a novel device dedicated to recanalization of chronic total occlusions (CTO), relies on a monorail catheter delivering vibrational energy to facilitate the crossing of occluded coronary arteries. METHODS We included de novo or restenotic occlusions in native coronary arteri...
متن کاملCrossing Total Occlusions: Navigating Towards Recanalization
Chronic total occlusions (CTOs) represent the "last frontier" of percutaneous interventions. The main technical challenges lies in crossing the guidewire into the distal true lumen, which is primarily due to three problems: device buckling during initial puncture, inadequate visualization, and the inability to actively navigate through the CTO. To improve the success rate and to identify future...
متن کاملChronic Total Occlusions: New Pathways to Success
Yet the barriers to treatment for this group remain formidable and include sometimes long procedure duration and cost [2], perception of higher complication rates [3], and lack of clinical evidence to support CTO PCI, include procedures, that on average, take longer, cost more and have higher complication rates. There is also a perception that there is a relative lack of clinical evidence to su...
