Is magnetic resonance image guidance the key to opening chronic total occlusions?
Through progressive plaque growth or fibrotic organization of occlusive thrombus, atherosclerosis may result in chronic total occlusion (CTO) of a major arterial conduit. If CTO develops slowly, collateral pathways may supply sufficient perfusion to retain tissue viability despite occlusion of the major inflow conduit. However, such collateral-mediated perfusion rarely matches that provided by ...
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...
متن کاملAdaptive Total Variation Image Deconvolution: Application to Magnetic Resonance Imaging
This paper presents a new approach to image deconvolution (deblurring), under total variation (TV) regularization, which is adaptive in the sense that it doesn’t require the user to specify the value of the regularization parameter. We follow the Bayesian approach of integrating out this parameter, which is achieved by using an approximation of the partition function of the Bayesian interpretat...
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...
