Filter this list of studies by location, status and more.

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

   Scottsdale/Phoenix, Ariz.

   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.

2. Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction Trial

   Rochester, Minn.

   The objective of this trial is to evaluate the effectiveness of left atrial appendage exclusion (LAAE) for the prevention of ischemic stroke or systemic arterial embolism in subjects undergoing cardiac surgery who have risk factors for atrial fibrillation and ischemic stroke.

3. Expanded Access Protocol of Patisiran for Patients With Hereditary ATTR Amyloidosis (hATTR)

   Rochester, Minn.

   The purpose of this study is to provide expanded access of patisiran to patients with hereditary transthyretin-mediated amyloidosis (hATTR).

4. A Study to Evaluate Aortic Dilatation in Patients with Conotruncal Abnormalities

   Rochester, Minn.

   The purpose of this study is to assess operative and postoperative outcomes after aortic valve surgery, evaluate for changes in ascending aorta diameter by comparing pre-operative CT imaging to measurements on follow-up imaging, and examine late outcomes and functional status during the follow-up period with specific focus on mortality, need for re-operation and incidence of aortic dissection.

5. A Study to Evaluate Perceptions of Midline Sternotomy Scar in Children and Young Adults

   Rochester, Minn.

   The purpose of this study is to evaluate how children and young adults perceive their midline sternotomy scars (in terms of appearance, associated symptoms, consciousness, satisfaction with appearance/symptoms, and impact on quality of life)? 

6. A Study to Analyze Tacrolimus Metabolism in Heart Transplant Patients

   Jacksonville, Fla.

   The puprose of this study is to evaluate pharmacogenomic differences of CYP 3A5 in heart transplant patients, to determine dose ranges and pharmacodynamics properties of tacrolimus metabolism based on CYP 3A5 genotype/phenotype combinations, and to assess whether CYP3A5 polymorphism influences post-transplant outcomes including survival, rejection and infection rates.

7. Study to Determine the Accuracy of a New Venous Air Plethysmograph in People with Normal, Incompetent, and Obstructed Venous Hemodynamics.

   Rochester, Minn.

   The purpose of this study is to determine the accuracy (sensitivity, specificity, negative predictive value, positive predictive value) of a new venous air plethysmograph in people with normal, incompetent, and obstructed venous hemodynamics.

8. A Repository of Atria Tissue for the Investigation of Atrial Pathophysiology in Patients with Atrial Fibrillation

   Rochester, Minn.

   The purpose of this study is to collect surgically removed atrial tissue for genetic, pathologic, metabolic, and molecular studies in patients with or without a history of atrial fibrillation.

9. A Study to Evaluate DDP3 as a Predictor of Cardiogenic Shock in Patients Presenting with Cardiac Symptoms

   Rochester, Minn.

   The purpose of this study is to evaluate whether DDP3 identifies patients at early risk of cardiogenic shock presenting with STEMI in order to benefit from more aggressive cardiology scrutiny.

    

    

10. A Study to Establish a Registry for the Pulmonary Hypertension Association

    Jacksonville, Fla.

    The objectives of this study are to measure and improve quality of care (including assessing differences in adherence to evidence-based guidelines and establishing benchmarks for health outcomes); determine the clinical effectiveness, comparative effectiveness, and cost effectiveness of treatment approaches; understand risk factors for outcomes and regional/center differences; and facilitate funded clinical trials of new therapies and collaboration with the PAH community at large, including providers, patients, and their caregivers.
