Filter by:The objective of this study is to provide an ongoing evaluation of clinical outcomes associated with the GORE Flow Reversal System and the GORE Embolic Filter when used for embolic protection during carotid artery stenting.
Cerebral embolization during carotid artery stenting (CAS) can often precipitate severe adverse neurological effects. Most major clinical studies of CAS have used distal filters for cerebral protection and have compared the neurologic complication rates with those of carotid endarterectomy (CEA). Many currently available embolic protection devices, however, have limited efficacy in capturing microembolic debris that is liberated during stenting, pre-dilatation and post-dilatation. Distal protection systems are furthermore limited by the need to cross the lesion prior to deployment. Some studies have shown a relatively high incidence of cerebral infarction even when distal protection devices are employed. Cerebral protection with carotid flow reversal is a method that was developed by Parodi, et al., as an alternative to the use of distal protection devices. While novel in its approach, this method too has its limitations. Criado, et al., developed a derivative technique that employs carotid flow reversal prior to traversing the stenosis and can be accomplished by directly accessing carotid anatomy without the use of the transfemoral approach. Major benefits to this method include the ability to perform the procedure on patients with severe carotid tortuosity and difficult aortic arch anatomy.
The aim of this study was to measure the effect of moderate and intensive lipid-lowering treatment with rosuvastatin on the carotid intima-media thickness (CIMT) as a surrogate marker of cardiovascular risk.
Heart attacks and strokes caused by the unstable atherosclerotic plaques remain the leading cause of death in the United States. Unstable plaques often have more fat than stable plaques. This study will investigate if a treatment with LDL-lowering plus HDL-raising compared with LDL-lowering alone would more effectively reduce the plaque fat content assessed by magnetic resonance imaging (MRI), therefore, further reducing heart attacks and strokes.
The purpose of this study is to get outcomes data for the Adapt Monorail Carotid System used in conjunction with the FilterWire Embolic protection system for treatment of patients that suffer from carotid artery stenosis and that cannot have surgery due to high risk factors.
Single center randomized clinical trial, to evaluate the safety and efficacy of carotid artery stenting using the RX ACCULINK™ Carotid Stent System with RX ACCUNET™ Embolic Protection System or PercuSurge GuardWire® 3-6 Temporary Occlusion and Aspiration System using Angiomax (bivalirudin)versus heparin as the anticoagulant for treatment of occlusive carotid artery disease in low and high risk patient cohorts.
This study will examine the effect of statin and niacin therapy on carotid plaque biomarkers
The purpose of this study is to detect new ischemic lesions after carotid artery stenting (with the Cristallo Ideale stent), in patients with high grade carotid artery stenosis, by diffusion-weighted magnetic resonance imaging (DW-MRI), using the endovascular proximal flow blockage (Mo.Ma device) for cerebral protection.
The investigators hypothesized that circulating endothelium-derived microparticle (EMP) may be a useful surrogate marker of atherosclerosis and future episode of cerebrovascular events. Peripheral blood is drawn at the time of carotid ultrasound examination. Circulating EMPs are counted using flow-cytometry. The correlation among circulating EMP, ultrasound findings, and atherosclerotic risk factors are determined by multiple stepwise regression analysis. The prevalence of cerebrovascular events is also determined during 3-year follow-up period.
The objective of the ARMOUR study is to evaluate the safety and effectiveness of the Mo.Ma proximal flow blockage cerebral protection device for patients at high surgical risk for carotid endarterectomy who undergo carotid artery stenting
