A 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 کاملIntracoronary imaging in chronic total occlusions
Chronic total occlusion (CTO) intervention constitutes approximately 10–20% of all angioplasty procedures at selected centers. Benefits of CTO revascularization, in addition to relief of angina, include improvement of left ventricular function, reduced risk of major adverse cardiac events and potentially increased survival. Although several techniques, devices and guidewires have been developed...
متن کاملMicrovascular dysfunction in chronic total coronary occlusions.
BACKGROUND Microvascular dysfunction is defined as reduced coronary flow reserve in the absence of an epicardial stenosis. This study determined its prevalence and relation to regional myocardial function in chronic total coronary occlusions (TCO). METHODS AND RESULTS After recanalization and stenting of a TCO (duration, >4 weeks) in 42 patients, coronary flow velocity reserve (CFVR) was meas...
متن کاملNew Advances in Chronic Total Occlusions.
Coronary chronic total occlusions (CTOs) still represent the greatest technical challenge that interventional cardiologists face. CTOs remain seriously undertreated with percutaneous techniques, far below their prevalence. One reason for the low uptake was the suboptimal CTO percutaneous coronary intervention (PCI) success rates over a long period of time. During the last years, dedicated group...
متن کاملAntegrade Techniques for Chronic Total Occlusions
By convention, a total obstruction of the coronary artery with no flow at the occluded segment that has been present for at least 3 months is termed as chronic total occlusion or CTO. This is to be distinguished from a sudden occlusion of the coronary artery lumen by a thrombus during an acute myocardial infarction. Percutaneous coronary intervention (PCI) of CTO is increasingly being performed...
