1. A Study of Long-Term Outcomes of Cardiac Resynchronization Therapy Recipients with Congestive Heart Failure

   Rochester, Minn.

   The purpose of this study is to determine the long-term outcome of cardiac resynchronization therapy (CRT) recipients with congestive heart failure and any indications for CRT at Mayo Clinic.   

2. 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.

3. 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).

4. 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.

5. Genetic Predictors of QT Prolongation with Anti-arrhythmic Medication

   Rochester, Minn.

   The purpose of this study is to assess the ability of common genetic variants in aggregate to predict drug-induced QT prolongation in patients being started on dofetilide. We will examine the predictiveness of a QT genotype score on QT prolongation in patients admitted for dofetilide initiation.
    

6. A Study of Macitentan in Pulmonary Hypertension After Left Ventricular Assist Device Implantation

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate the effect of macitentan 10 mg on pulmonary vascular resistance as compared to placebo in subjects with pulmonary hypertension after left ventricular assist device (LVAD) implantation

    

7. 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.

8. A Study for Sources of Pulmonary Congestion Associated with Heart Failure

   Rochester, Minn.

   The purpose of this study is to measure and identify chest fluid volumes associated with heart failure and to determine their impact on lung structure and function, and also assess the effect of body position on shifts in fluid and the effects of this on lung function, mechanics and gas exchange.

9. 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.

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.
