Filter by:To assess the safety and feasibility of Volcano Corp Eagle Eye Gold Catheter system to correlate the presence and characteristic of carotid artery atherosclerotic disease with anatomic and histologic analysis.
The purposes of this study are to determine: 1. Inter-site variability in CIMT image measurement using SonoCalcTM. 2. If non-sonographer health care professionals working in an office practice setting can be trained to follow a carotid scanning protocol that permits (a) accurate measurement of CIMT and (b) determination of plaque presence. 3. If (a) CIMT measurements and (b) determination of plaque presence by non-sonographer health care professionals are bioequivalent to those made by a core laboratory. 4. If CIMT measurements and plaque assessment performed in office practices lead to meaningful changes in patient and physician behavior related to cardiovascular disease prevention.
To determine the rate of progression of sub-clinical cardiovascular disease as measured in carotid intimal medial thickness over a period of 8 to 10 years.
The primary objective of this study is to compare the safety and effectiveness of the Cordis Nitinol Carotid Stent and Delivery Systems (5.5 F and 7 F) with the ANGIOGUARD XP distal protective device to CEA in the treatment of carotid artery disease in patients at increased risk for surgery.
The primary objective of this study is to assess the outcomes of stenting with distal protection in the treatment of obstructive carotid artery disease during peri-approval/initial commercialization in relation to the outcomes of the Sapphire Clinical Trial. The devices to be utilized are the Cordis PRECISE Nitinol Stent Systems and the Cordis ANGIOGUARD™ XP Emboli Capture Guidewire (ECGW).
The EFFERVESCENT trial is designed to evaluate the effects of a specific ARB, called valsartan, on atherosclerosis. The investigators want to know if treatment with valsartan will increase the blood levels of markers responsible for repair of the vessel wall, reduce oxidation and inflammation, improve the function of the blood vessels, and arrest or slow down the progression of atherosclerosis over time.
1. To evaluate the safety and efficacy of the over-the-wire (OTW) ACCULINK (tm) System in patients deemed to be either at high risk or unsuitable for carotid endarterectomy (CEA) 2. To evaluate the efficacy of the OTW ACCUNET System in patients deemed to be either at high risk or unsuitable for carotid endarterectomy (CEA). 3. To demonstrate equivalence in the safety and performance of the RX ACCULINK Carotid Stent System and RX ACCUNET Embolic Protection System and the corresponding OTW devices.
This purpose of this study is to collect data on the FDA-approved ACCULINK(TM) Carotid Stent System and FDA 510(k)-cleared ACCUNET(TM) Embolic Protection System for the treatment of patients with atherosclerotic disease, when used by physicians under commercial use conditions.
The primary objective of this study is to assess the safety and effectiveness of stenting in the treatment of obstructive carotid artery disease. Secondary objectives are the assessment and standardization of optimal operator techniques and successful deployment and retrieval of the AngioGuard XP Distal Protection Device. This is a single center, prospective, open-label feasibility study. The study population will consist of patients with atherosclerotic obstructive or post-endarterectomy restenotic lesions in native carotid arteries. The intention is to include patients with both types of lesions.
The advent of new antiretroviral agents, in particular Highly Active Antiretroviral Therapy (HAART), spectacularly reduced HIV-associated morbidity and mortality. However, new complications have appeared in HIV-infected patients treated by with HAART such as dyslipidemia, insulin resistance, diabetes mellitus, and related cardiovascular complications including acute coronary syndromes, peripheral vascular disease, and stroke have been reported. A linear association has been proved between increased intima-media thickness of the common carotid artery (CCA-IMT), aortic stiffness (pulse wave velocity [aPWV]) and incidence of cardiovascular events suggesting that IMT and aPWV could be considered as an early marker of atherosclerosis. The progression of IMT has been shown to be predictive of cardiovascular events. Case control and longitudinal studies but not all have suggested an increase CCA-IMT in HIV-infected patients under HAART compared with non-HIV infected patients with different progression. The aim of this study was to examine the effects of pravastatin on CCA-IMT and aortic stiffness in dyslipidemic HIV-infected patients receiving HAART by using a high-resolution echotracking system. Patients in the pravastatin group were consecutively recruited in four department of infectious diseases if they fulfilled the following criteria : (1) HIV-infected treated with HAART for > 12 months 2) with dyslipidemia, defined as fasting serum LDL cholesterol > 160 mg/dL before initiation of pravastatin, (3) treated with pravastatin > 12 months and one more coronary risk factor. The patients in the control group were selected consecutively in the same departments among 1) HIV-infected patients treated with HAART > 12 months 2) fasting serum LDL cholesterol > 160 mg/dL 3) without lipid-lowering drugs and one more coronary risk factor. Cases and control patients were matched for age, gender and tobacco consumption. Using data from Mercie et al., inclusion of 42 patients in pravastatin and control groups was the minimum sample size needed for detection of a 6.5% difference in CCA-IMT, in a two-sided test (a = 0.05, b = 0.20). The protocol of the study, sponsored by the French Society of Cardiology was approved by the Committee for the Protection of Human Subjects in Biomedical Research of Pitié-Salpétrière University hospital in Paris. Written informed consent to participate in the study was obtained from each patient.
