Active clinical trials for "Vascular Diseases"

The Veterans Administration Patient Study examined the progression of peripheral arterial disease (PAD) in patients with large vessel PAD or isolated small vessel PAD. The Community Follow-up Study following subjects with and without PAD from a previous cohort to determine subsequent coronary heart disease and cardiovascular disease morbidity and mortality.

The aim of this study is to use the high resolution of optical coherence tomography to assess the prevalence of different types of cardiac allograft vasculopathy (CAV) in cardiac transplanted patients and correlate those results with the level of immunosuppression

The purpose of this study is to compare magnetic resonance angiography (MRA) using gadoterate meglumine to clinically obtained MRA using gadobutrol. The specific aims are to show: Carotid, chest, and abdomenal MRA with gadoterate meglumine has a comparable image quality and diagnostic confidence to MRA using gadobutrol. Carotid, chest, and abdomenal MRA with gadoterate meglumine has a comparable accuracy for vascular lesion and stenosis detection compared to MRA using gadobutrol.

The PRIME Registry is a multi-center, observational study designed to evaluate immediate and long-term outcomes (36 months) of endovascular revascularization in patients with critical limb ischemia (CLI) and advanced peripheral artery disease (PAD).

To systematically develop, test, and refine peripheral vascular electrocardiography-gated fast spin echo magnetic resonance imaging for the accurate diagnosis of peripheral arterial disease without gadolinium contrast. To test prospectively the accuracy of fast spin echo in peripheral arterial disease patients, compared with bolus-chase and time-resolved gadolinium enhanced magnetic resonance angiography. Additionally, as a substudy of this project, we will compare our fast spin echo approach with alternative non-contrast-enhanced magnetic resonance imaging methods such as time-of-flight and steady-state gradient echo imaging. The overarching goals of our research are to develop and validate a peripheral magnetic resonance imaging technique that accurately depicts anatomy and disease without exposing patients to exogenous contrast material and its associated risks.

The Zenith TX2 Low Profile TAA Endovascular Graft extended study is to collect confirmatory safety and effectiveness data. The Zenith TX2 Low Profile TAA Endovascular Graft is indicated for the treatment of patients with a descending thoracic aortic aneurysm or penetrating ulcer and has an anatomy suitable for repair.

To evaluate early ambulation in patients who receive the StarClose™ VCS post-percutaneous diagnostic procedure.

Collect data on the use of the Angio-Seal Evolution Device in diagnostic and interventional patient populations.

Peripheral venous disease occurs when a vein becomes damaged or blocked. It can occur almost anywhere in the body, but is most common in the arms and legs. This study will examine people who participated in a previous venous disease study to evaluate changes in leg veins and venous disease status over a period of 11 years.

The DEScover Registry is designed to observe the results of using Drug Eluting Stents (DES) in patients in a real-world setting. The stents being observed are not investigational, that is, they have been approved for use in the general population.
