In this study, we will collect congenital vascular malformation (CVM) tissue samples to examine the vascular and neurological phenotypes in the lesions. We will develop a repository of the remaining CVM samples for our future research which will substantially decrease the need for specimen collections from future CVM subjects. We will also collect blood samples and characterize proteins and RNAs profiles from serum exosomes and metabolites from CVM patients, which will help us to understand the progressive mechanism of CVM.
The purpose of this study is to determine the effectiveness of treating narrowing or blockages of arteries in legs (Peripheral Artery Disease) with a small drug coated balloon that is inserted into your leg (called Ranger or IN.PACT) alone versus using the same balloon (Ranger or IN.PACT) in addition to the JetStream XC atherectomy system.
The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.
This study will evaluate the safety and effectiveness of the Nellix System among a wide range of physicians and in consecutively enrolled subjects to assess safety and effectiveness outcomes. Following appropriate government and ethics committee/IRB approval the Nellix® EndoVascular Sealing System will be implanted into eligible patients who are adequately informed and have consented to join the study. Enrolled patients will undergo a high resolution, contrast-enhanced computed tomography angiography (CT) scan of the relevant aortic and aortoiliac vasculature within three months of the scheduled procedure and at specified follow-up intervals post-implantation. Follow-up visits will occur at 30 days, 6 months, and annually to 5 years to assess aneurysm morphology, the status of the implanted devices, and relevant laboratory test results.
This study will assess patients with acute ischemic strokes being treated with n-Butylphthalide (NBP) softgel capsules. This is a phase II study to evaluate the safety of NBP treatment. The medication has the potential to reduce impairment of memory function, cerebral edema, and disruption of the blood-brain barrier.
The purpose of this study is to evaluate the use of a non-contrast MRI for the assessment of the vasculature of the lower extremity anatomical regions. Patients eligible for this study must have been referred for a clinical contrast enhanced CT scan or an invasive catheter angiography. The overall image quality and diagnostic accuracy of the non-contrast MRI will be compared to current clinical standards of care, such as contrast enhanced MRI, CT, and invasive angiography.
This study will examine changes in brain architecture that are associated with vascular parkinsonism, in comparison to Parkinson's disease. We will do this by using advanced imaging techniques to compare brain structure between subjects with vascular parkinsonism and Parkinson's disease.
The Actelion SOPRANO study is a prospective, multicenter, double-blind, randomized, placebo-controlled, parallel-group Phase II study to evaluate the safety and effect of macitentan on pulmonary vascular resistance in subjects with pulmonary hypertension after left ventricular assist device (LVAD) implantation. Male and female patients 18 years of age or older who have had surgical implantation of LVAD may be eligible to participate in this study.

This study is being conduct to assess the safety and effectiveness of a Study Sevice,GORE® EXCLUDER® Conformable AAA Endoprosthesis, in patient's with an aneurysm in their abdominal aorta. In this research study, the Study Device will be placed inside the abdominal aorta (in the approximate area of the belly button) and the Study Device will extend into both leg arteries. The Study Device will block the aneurysm (the weakened and bulging part of the artery) in the abdominal aorta from blood flow while maintaining blood flow to the arteries in the legs. Information will be collected on the performance of the Study Device for up to five (5) years.
The PREMIERS study is a proposal for conducting an adequately powered two center phase III randomized controlled trial to test whether intensive periodontal treatment reduces the risk of recurrent vascular events among ischemic stroke and TIA survivors. The study uses the resources in both states including established
dental centers, Joint Commission Certified Stroke Centers, the Schools of Public Health, and the Institute for Partnerships to Eliminate Health Disparities. The proposal addresses specific issues with regards to recruitment of African-American and rural stroke/TIA patients advocating the use of culturally appropriate strategies to educate the study subjects regarding stroke, periodontal disease and the periodontal stroke link.
The study proposes to utilize economic evaluation of the periodontal intervention from the budgetary
perspective. The focus will be on the financial sustainability of providing aggressive periodontal therapy (with
certain, although relatively low expenditures) in exchange for a reduction of uncertain recurrent vascular events
that may require high cost emergency department utilization and/or inpatient care. The sustainability of the
proposed intervention after the completion of the project is integrally linked to the health economic assessment
to show the health care cost savings. By integration with a rural primary care center, with an African American
majority and households with average incomes below the state average, the study ensures that the proposed
intervention to reduce stroke disparity is applicable to this target population.
