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

1. Prevalence of Transthyretin Cardiac Amyloidosis in Clinically Significant Aortic Stenosis

   Rochester, Minn.

   The purpose of this study is to determine the prevalence of TTR-CA in a community-based cohort of moderate and severe aortic stenosis patients using 99mTc-PYP single-photon positive emission computed tomography with computed tomography (SPECT/CT).

2. A Study to Evaluate Wellness Coaching for Caregivers of Thoracic Transplant Candidates

   Rochester, Minn.

   The purpose of this study is to examine the effects of a health coaching intervention on the stress and burden of caregivers of patients awaiting heart or lung transplant.

   Hypotheses:  Caregivers will have traits and behaviors pre-transplant that will predict caregiver readiness, quality of life, and transplant recipient outcomes. Specifically, thoracic pre-transplant caregivers report stress, symptoms of anxiety or depression, and perceive high caregiver burden. These factors may be amenable to pre-transplant intervention to improve overall patient and caregiver outcomes.

   Aims, purpose, or objectives:  We will conduct a pilot trial to test whether caregivers of heart and lung transplant candidates who receive wellness coaching will experience improvement in caregiver-related distress. We will also explore the relationship between caregiving and factors such as uncertainty, resilience, stress level, and affect.

3. 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.

4. 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.

5. A Study of Sexual Dysfunction in Patients with Hypertrophic Obstructive Cardiomyopathy Undergoing Septal Myectomy

   Rochester, Minn.

   The purpose of this study is to determine how many patients suffer from sexual function problems and ascertain if they are improved or modified by cardiac surgical intervention.

6. Evaluation of the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis in the Treatment of Thoracoabdominal and Pararenal Aortic Aneurysms

   Rochester, Minn.

   Prospective, non-randomized, , multicenter study with two independent arms: * Primary Study Arm - TAAA and Pararenal aneurysms requiring only TAMBE System. Hypothesis-driven analysis. * Up to 65 additional subjects may be implanted in Continued Access Phase under the Primary Study Arm only * Secondary Study Arm - TAAA requiring TAMBE System and CTAG Device(s). Non hypothesis-driven analysis. Minimum: 122 implanted subjects. Maximum: 202 implanted subjects with up to 65 additional subjects implanted in Continued Access (Primary Study arm)

7. 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.

8. 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)? 

9. MediCool Protocol

   Rochester, Minn.

   The purpose of this study is to assess termination of atrial fibrillation (AF) following delivery of cold treatment to the oblique sinus using an experimental cooling module.

    

10. A Study to Evaluate Noninvasive Ultrasound Elastography of Kidney and Lung in Assessment of Volume Status in ICU Patients

    Rochester, Minn.

    The primary purpose of this study is to assess the feasibility of performing lung and kidney and lung ultrasound elastography among patients with critical illness from different etiologies that could be associated with volume overload.
