Filter by:The main objective of the study is to survey and improve the IVUS image quality and X-ray system interoperability by collecting Procedural Data (e.g. raw, pre- processed ultrasound and X-ray data, endpoints such as fluoroscopy time, contrast load and radiation dose, workflow details) during routine intravascular procedures to assure adherence to the high standards of quality during care delivery and promote procedural standardization.
The goal of this clinical trial is to test the Thor system in adult (≥ 18 year old) patients with de novo (new, never treated) calcified lesions in infrainguinal (leg) arteries (peripheral artery disease or PAD). The main question[s] it aims to answer are: - Is the Thor system safe in treating these lesions - Does the Thor system work to treat these lesions Participants will: - Receive treatment with the Thor system - Have follow-up visits at Discharge, 30 days, 6 months, and 12 months
The objective of this study is to obtain outcomes following dissection repair with the Tack Endovascular System in a broad population of patients undergoing endovascular treatment of lesions within the superficial femoral, popliteal, peroneal, and/or tibial arteries.
Sympathetic overactivity partly promotes the development of peripheral artery disease which mainly leads to ischemia of the lower limbs. Endovascular arterial denervation (ED) is a minimally invasive technique which could deliver Radiofrequency energy by a multi-electrode catheter to the Lower limb artery to restore Sympathetic activity. The purpose of this study is to evaluate the effects of multi-electrode radiofrequency ablation system on lower limb ischemia with PAD.
Participants with chronic kidney disease (CKD) are at a higher risk of developing atherosclerotic peripheral artery disease (PAD). Retention of uremic toxins such as indoxyl sulfate (IS), p-cresyl sulfate (PCS) and trimethylamine N-oxide (TMAO) during CKD is detrimental to endothelial and vascular function and can predispose to the development and progression of PAD. Many of the uremic toxins originate from gut microbial metabolism. Removal of these uremic toxins by carbonaceous oral adsorbent is beneficial, slowing down the deterioration of renal function and delaying the need for dialysis in CKD patients. However, if carbonaceous oral adsorbent could also improve vascular function and clinical outcomes in CKD patients with established PAD, remains unknown. In this proposal, the investigators aim to determine the therapeutic impact of a carbonaceous oral adsorbent made of activated bamboo charcoal (ABC) with/without probiotics on the endothelial/vascular function, CV outcome and mortality in CKD patients with PAD. In addition, the investigators hypothesize that circulating long noncoding RNA (lncRNA) expression profiles and metabolome may serve as a sensitive and reliable biomarker to predict the adverse CV outcomes and death in CKD patients with established PAD. In addition, it is hypothesized that circulating lncRNAs and linked to adverse CV outcomes in CKD patients with PAD are associated with dysbiosis of gut microbiota. The investigators also hypothesize that the administration of ABC could normalize the dysbiosis of gut microbiota, dysregulated circulating lncRNAs and metabolome that are linked to adverse CV/limb outcomes in CKD patients with PAD. This will be a prospective, randomized, open-labeled, blinded end-point trial for 6 months, followed by integrated assessment of endothelial/vascular function, changes in conventional athero- and inflammation-relevant biomarkers, circulating long noncoding RNAs, metabolome, and gut microbiota at baseline, ends of the 3rd and 6th month, as well as clinical CV, renal and limb outcomes up to 3 years.
The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON™ Atherectomy System, within the initial launch phase of the product in the market.
Objectives 1. The VQI-VISION Paclitaxel Device Safety Analysis seeks to assess the comparative safety of paclitaxel-coated balloons and stents in the treatment of PAD through analysis of the Vascular Quality Initiative (VQI) Peripheral Vascular Intervention (PVI) registry module with linkage to claims. By linking VQI patients to Medicare claims retrospectively from 2012 to 2016, we will be able to identify additional paclitaxel devices enabling longitudinal follow-up of mortality out to 5 years for paclitaxel-eluting stents and 3 years for paclitaxel-coated balloons. 2. To analyze factors associated with mortality, specifically comparing paclitaxel patients surviving vs. paclitaxel patients with mortality. The goal is to identify independent factors predictive of mortality in US pivotal trials and model registry data exposures with sufficient factors to track competing risk paradox and show emulation or not of mortality outcomes with both PTX and PTA exposures. 3. To confirm the effectiveness of paclitaxel devices by comparing reintervention for paclitaxel and non-paclitaxel devices. In-hospital mortality from open and percutaneous target vessel revascularization (TVR) will be reported to determine the impact of subsequent revascularizations on survival. Major amputation will be comparted for patients with chronic limb-threatening ischemia.

The study objectives of this projects are to examine the hypothesis that the sympathetic and blood pressure responses to exercise will be attenuated during and after heat exposure in patients with peripheral artery disease, via altering the sensitivity of the muscle afferent receptors.
