1. A Study of Patients Who Underwent Intravascular Ultrasound to Create a Registry

   Rochester, Minn.

   Since Intravascular Ultrasound (IVUS) emerged as a significant tool for detection of early coronary atherosclerosis, we are maintaining an ongoing registry of those patients who have had this procedure done to provide more information regardint the successful interpretation of these intravascular ultrasound (IVUS). 

2. Study to Validate the Use of Hand-Held Mobile 3D Scanning to Obtain Volumetric Measurements for Staging Disease Severity in Lymphedema Patients

   Jacksonville, Fla.

   The purpose of this study is to validate the use of LymphaTech's Hand-Held Mobile 3D Scanning to obtain volumetric measurements in order to stage disease severity in patients diagnosed with lymphedema, and also serve as an imaging biomarker for microsurgical treatment response.

3. Apixaban in Preventing Secondary Cancer Related Blood Clots in Cancer Patients Who Have Completed Anticoagulation Therapy

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   This randomized phase III trial studies the best dose of apixaban and how well it works in preventing secondary cancer related blood clots in cancer patients who have completed anticoagulation therapy. Apixaban may stop the clotting of blood by blocking some of the enzymes needed for blood clotting.

4. International Bicuspid Aortic Valve Consortium (BAVCon)

   Rochester, Minn.

   Bicuspid aortic valve (BAV) disease is the most frequent congenital cardiac malformation, occurring in 0.5-1.2% of the US population. In young adults, it is generally a benign abnormality; but in older adults it is associated with thoracic aortic aneurysm or dissection in 20-30% of those with BAV. BAV is strongly associated with early development of aortic valve calcification or incompetence in >50% of BAV patients, and accounts for ~40% of the >30,000 aortic valve replacements (AVR) performed in the US each year. Yet, we know little of the etiology, cellular events and modifiers of progression of BAV to calcific aortic valve disease and we still do not understand the genetic cause(s) of BAV despite evidence for its high heritability.

   The Specific Aims of this study are:

   1. To identify the genetic causes of bicuspid aortic valve disease and its associated thoracic aortic disease.

   2. To identify potential pathways to predict the clinical course of BAV disease and for treating human BAV disease.

   To achieve these aims, we have created the International Bicuspid Aortic Valve Consortium (BAVCon), a consortium of institutions with cohorts of BAV patients and the expertise to fulfill the performance of these aims.

5. IPSS Consortium Study

   Rochester, Minn.

   The overall objective of our network of investigators is to develop and conduct clinical trials and other large multi-centre studies in childhood stroke. Our specific aims are:

   Objective 1: To ascertain in a prospective, consecutive cohort study the numbers of newborns and children with ischemic stroke, their stroke sub-types and risk factors, their current treatments and outcomes within our centers. These data will provide the rationale and feasibility data for our group to design and implement the initial randomized controlled trials (RCTs) in paediatric stroke as well as other fundable grant proposals.

   Objective 2: To develop standardized data collection forms and an appropriate database with web-based data entry from multiple study sites.

   Objective 3: To develop standardized protocols for (1) diagnosis, (2) investigation of risk factors, (3) outcome assessment and 4) antithrombotic therapies of neonates and children with arterial ischemic stroke (AIS) and cerebral sinovenous thrombosis (CSVT)

   Objective 4: Obtain grant funding to support and conduct additional multi-centre IPSS sub-studies

6. Golden Calf Trial

   Eau Claire, Wis., Rochester, Minn., La Crosse, Wis.

   The purpose of this study is to determine whether prescribing apixaban (Eliquis®) is more effective in treating and preventing pulmonary embolisms and subsequent DVTs than monitoring the calf DVT with ultrasound imaging alone.

7. Vascular Diseases Biorepository

   Rochester, Minn.

   The eventual goal of this study is to identify genetic and proteomic markers that may influence susceptibility to vascular diseases including peripheral arterial disease, pulmonary hypertension, carotid artery stenosis, arterial aneurysmal disease, fibromuscular dysplasia, congenital heart disease and other less common diseases that affect the blood vessels.

8. Study of Intravenous Sodium Thiosulfate in Acute Calciphylaxis Patients

   Jacksonville, Fla.

   The purpose of this study is to evaluate the effectiveness and safety of intravenous Sodium Thiosulfate Injection for treatment of acute calciphylaxis-associated pain in chronic hemodialysis patients.

9. Complex Aortic Aneurysm Repair With Fenestrated Stent Grafts

   Rochester, Minn.

   This study will compare two groups of subjects with complex abdominal aortic aneurysms. It will compare their clinical outcomes and quality of life measures. The group being treated in this study will have their aneurysms repaired by an endovascular approach using Zenith® Fenestrated AAA Endovascular Graft. This group will be compared to a group of 461 patients (historical cohort) whose complex aneurysms were treated by open surgical repair.

10. Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial

    Rochester, Minn., Jacksonville, Fla.

    Carotid revascularization for primary prevention of stroke (CREST-2) is two independent multicenter, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1:1 ratio to endarterectomy versus no endarterectomy and another will randomize patients in a 1:1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed.
