Evaluation of Tissue Perfusion in Peripheral Arterial Disease (EVTI-PAD)
Peripheral Arterial DiseaseChronic Limb-Threatening Ischemia1 moreIn this prospective single-center observational study, arterial perfusion in patients with lower limb peripheral arterial disease will be assessed with standard diagnostic tools (toe pressure, trans-cutaneous oxygen pressure, ankle-brachial index and fluorescence angiography) before and after standard revascularization procedures (open surgery and/or angioplasty).
Clinical Testing Study in Peripheral Arterial Disease
Peripheral Arterial DiseaseThe Purpose of the Clinical Testing Study in Peripheral Arterial Disease (CTS-PAD) study is to compare measurement outcomes between conventional Ankle-Brachial Index test for Peripheral Arterial Disease with a new imaging technology from which the same data can be derived, in a series of patients referred to Vascular Surgery Clinics at the University of Rochester for suspected peripheral arterial disease.
Popliteal Artery of Treatment With Balloon Angioplasty vs. SUPERA VERITAS Peripheral Stent System...
Peripheral Vascular DiseaseUnblinded, randomized, balanced trial comparing 12 month target lesion patency rates of the IDEV SUPERA VERITAS peripheral stent system to PTA in the treatment of obstructive atherosclerotic popliteal artery disease.
Clinical Utility of Endothelial Dysfunction in PAD
Peripheral Arterial DiseaseThis study will seek to determine whether non-invasive measures of endothelial function have utility as surrogate markers of cardiovascular risk in patients with peripheral arterial disease undergoing vascular surgery. Measurements of endothelial function will be made before and after initiation of atorvastatin, ascorbic acid, or placebo therapy during the pre-operative period. We will then examine cardiovascular events following surgery. We hypothesize that patients who have no improvement in endothelial function will have increased cardiovascular risk compared to patients with improvement in endothelial function.
Short vs Long Duration Dual Antiplatelet Therapy in Patients Undergoing Lower Extremity Endovascular...
Peripheral Arterial DiseaseEndovascular ProceduresThe primary objective of the trial is to evaluate short versus long duration dual antiplatelet therapy in patients undergoing lower extremity endovascular revascularization.
Prevention of Restenosis Following Revascularization
Vascular DiseasePeripheralThe purpose of this study is to investigate the prevention of Restenosis following Revascularization of the superficial Femoral Artery (SFA)
Understanding Angioplasty by the Chocolate PTA Balloon Catheter Compared to Conventional PTA Balloons...
Infrainguinal Peripheral Arterial DiseaseThe purpose of this study is to compare the Chocolate PTA Balloon to standard Percutaneous Transluminal Angioplasty (PTA) catheters. The investigators will use Optical Coherence Tomography (OCT) and Quantitative Vascular Angiography to evaluate the acute vascular response of vessels treated with the Chocolate Balloon to a standard balloon catheter, with the primary endpoint being luminal gain assessed by OCT lumen volume measurements.
Associations Between the Microbiome, Skeletal Muscle Perfusion, and Fitness Status
Heart FailureSystolic4 moreThe purpose of the study is to determine associations between fitness status, bacteria in the mouth, and the blood flow to muscle. This study is trying to find out if fitness status impacts the bacteria that are present in the oral microbiome (environment in the mouth) or the ability of the body to send blood to the skeletal muscle. Participants will complete all or some of the following: A mouth swab to assess the bacteria in their mouths. Produce a saliva sample into a tube. Cycle on a bike until you reach maximum effort. Undergo blood draws Wear a 24-hour non-invasive device that monitors blood pressure. Undergo a test to assess blood flow to the muscles measured with an ultrasound. Drink 70mL (1/3 of a cup) of concentrated beetroot juice once
The CLI-AMP Registry
Critical Limb IschemiaPeripheral Arterial Disease1 moreSingle-center, observational registry study with a prospective and retrospective arm to evaluate the impact of multidisciplinary CLI teams and protocol on amputation rates, vascular studies, revascularization, in-hospital and long-term outcomes.
Lovaza Therapy of Peripheral Arterial Disease
Peripheral Artery DiseaseSixty patients with mild-to-moderate PAD (ABI 0.4-0.9) and hypertriglyceridemia (>200 mg/dl) already treated with statins will be imaged at baseline and randomized to Lovaza and placebo for 12 months. MR imaging will be repeated at the end of the 12-month period. We hypothesize that treatment of hypertriglyceridemia in patients with PAD with Lovaza will reduce atherosclerotic plaque volume in the superficial femoral artery (SFA) by 2% over 1 year compared to placebo. Secondary aims will be to show improved plaque characteristics (thickened fibrous cap, reduced lipid-rich necrotic core, improved exercise calf muscle perfusion using first-pass contrast enhanced MRI and improved exercise treadmill performance with Lovaza compared to matching placebo.
