1. Transcatheter Aortic Valve Replacement to UNload the Left Ventricle in Patients With ADvanced Heart Failure (TAVR UNLOAD)

   Rochester, Minn.

   The objective of this study is to determine the safety and efficacy of transcatheter aortic valve replacement (TAVR) via a transfemoral approach in HF patients with moderate AS as compared with OHFT.

2. Neural Circulatory Control and SUDEP Risk.

   Rochester, Minn.

   The investigators believe epilepsy alters the way the body controls blood pressure, heart rate and breathing, and these changes increase the risk of sudden unexpected death in patients with epilepsy (SUDEP). SUDEP-7 is a risk scoring tool which may correlate with these changes to the heart and blood vessels. This research study measures those differences which may help identify new markers to help predict those patients at greatest risk in the future.

3. A Study to Evaluate Long-term Outcomes of Alcohol Septal Ablation for Hypertrophic Cardiomyopathy

   Rochester, Minn.

   The purpose of this study is to determine long term vital status, symptoms, and need for repeat procedure after alcohol septal ablation, to determine patient and procedural factors associated with successful alcohol septal ablation and need for repeat procedure, and to determine the impact of conduction abnormalities after alcohol septal ablation on long-term outcomes.

4. A Study of Biomarkers for Human Heart Failure

   Rochester, Minn.

   The purpose of this study is to attempt to establish the various ranges of proteins that can be assayed from the plasma and urine of patients with all classes of heart failure and MI (myocardial infarction).

5. A Study of Oxygen Cost of Exercise in Patients with and without Heart Failure

   Rochester, Minn.

   This study is being done to: (1) develop a simple tool to assess breathing muscle performance; (2) measure the oxygen cost of breathing during exercise; (3) measure the respiratory muscle blood flow requirements of hyperpnea during exercise; and (4) to quantify the energy cost of exercise in relation to disease severity.

6. Ultrasound-based Technology (similar to standard clinical echocardiography) for Measuring the Stiffness of Heart Muscle and Peripheral Arteries

   Rochester, Minn.

   The purpose of this study is for evaluating an ultrasound-based technology (similar to standard clinical echocardiography) for measuring the stiffness of your heart muscle and your peripheral arteries. This type of information may prove to be clinically important.

7. A Study of Levosimendan in Pulmonary Hypertension (PH) with Heart Failure (HF) and Preserved Left Ventricular Ejection Fraction (pEF) Patients

   Rochester, Minn.

   The purpose of this study is to evaluate for safety and effectiveness weekly, open-label doses of levosimendan over extended use in patients with pulmonary hypertension with heart failure and preserved left ventricular ejection fraction (PH-HFpEF).

8. 3D Echocardiography Volumetric Measurements in Patients with or without Valvular Heart Disease

   Rochester, Minn.

   The purpose of this study is to determine if 3D volumetric measurements will allow more robust quantification of valvular heart disease severity.

9. A Study to Evaluate Optimal Target of Activated Clotting Time During Percutaneous Coronary Intervention and Outcomes

   Jacksonville, Fla., Rochester, Minn.

   The primary research hypothesis is that in the modern cardiac catheterization laboratory, where PCI procedural duration is relatively short and rates of intracoronary stenting and dual antiplatelet therapy use is high, lower ACT targets, as compared with higher ACT targets, will be associated with lower rates of bleeding while having similar rates of ischemic events.

10. A Study to Evaluate the Safety and Effectiveness of the Multi-Electrode Radiofrequency Balloon Catheter for the Treatment of Symptomatic Paroxysmal Atrial Fibrillation

    Rochester, Minn.

    The primary objective of this clinical investigation is to demonstrate safety and effectiveness of the Multi-Electrode RF Balloon catheter for the treatment of drug refractory symptomatic paroxysmal atrial fibrillation.
