Below are current clinical trials.

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

1. A Study to Analyze Association of Frequent Premature Ventricular Complex with Stroke or Transient Ischemic Attack

   Rochester, Minn.

   The purpose of this study is to verify that high Premature Ventricular Complex (PVC) burden is associated with increased risk of stroke and/or Transient Ischemic Attack (TIA), to examine outcomes such as stroke/TIA, atrial fibrillation/flutter, and all-cause mortality associated with PVCs, and to evaluate whether PVCs are associated with development of appendage dysfunction.

2. A Study of the Effect of Myectomy on the Sudden Cardiac Death Risk in Hypertrophic Cardiomyopathy

   Rochester, Minn.

   The primary purpose/objective of this study is to determine whether myectomy as a management option for severe hypertrophic cardiomyopathy (HCM) reduces the incidence of sudden cardiac death.

3. Predictive Role of Non-Invasive Glucose Assessment During Pregnancy

   Rochester, Minn.

   This study aims to determine the value of regular, non-invasive [glucose] LabClasp monitoring during pregnancy.

4. Bioengineered Cardiac Tissue for Hypoplastic Left Heart Syndrome Analysis

   Rochester, Minn.

   The purpose of this study is to produce and characterize patient-specific cardiac tissue for Hypoplastic Left Heart Syndrome (HLHS) using reprogrammed cell technology.

5. A Study to Assess Non-invasive Arterial Air Plethysmography of Normal and Abnormal Arterial Hemodynamics

   Rochester, Minn.

   The purpose of this study is to determine the accuracy (sensitivity, specificity, negative predictive value, positive predictive value) of a non-invasive arterial air plethysmography prototype in people with normal and abnormal arterial hemodynamics.

6. (FMD Impact Registry) Fibromuscular Dysplasia Findings and Outcomes

   Rochester, Minn.

   To describe the clinical, laboratory, pathologic, imaging findings, therapy and outcomes in all patients with Fibromuscular Dysplasia (FMD) and/or segmental arterial mediolysis evaluated at Mayo Clinic retrospectively (back to 01/01/1990) and prospectively (starting 04/13/2016).

7. A Study to Evaluate the Impact of Menopause on Blood Pressure Regulation During Exercise

   Rochester, Minn.

   The purpose of this study is to determine how menopause influences blood pressure responses during exercise in women.

8. A Study of Heart Muscle Elasticity Measured by Echocardiography

   Rochester, Minn.

   The purpose of this study is to evaluate the possibility of using echocardiography to measure heart muscle elasticity in clinical practice.

9. A Study of Lung Ultrasound to Assess Extravascular Lung Water

   Rochester, Minn.

   The purpose of this study is to determine if lung ultrasound surface wave elastography (LUSWE) can accurately detect changes in lung elasticity (compliance) caused by the presence of extravascular lung water  (pulmonary edema).

10. His Bundle Pacing in Bradycardia and Heart Failure

    Rochester, Minn.

    Participants in this study will either have heart failure (HF) and are scheduled to undergo cardiac resynchronization therapy pacemaker (CRT-P) or cardiac resynchronization therapy defibrillator (CRT-D) implantation, or have atrioventricular (AV) block and are scheduled to undergo dual chamber pacemaker implantation. In this study additional heart rhythm measurements will be collected during the implant procedure to better understand how His bundle and/or parahisian pacing (HISP) effects electrical conduction in the hearts of patients with HF or AV block. The hypothesis is that His bundle or parahisian pacing (HISP) may normalize atrioventricular (AV) conduction with a narrow combination of the Q wave, R wave and S wave (QRS complex) in functional bundle branch block or conduction delay in patients with heart failure (HF).
