按院区、状态和其他条件筛选该研究列表。

1. Rivet PVS Therapy in Group 2C

   Rochester, Minn.

   The purpose of this study is to evaluate the safety, performance, and initial clinical efficacy of the Rivet PVS therapy in patients with symptomatic pulmonary hypertension.

2. A Study of the Impact of Cardiac Rehabilitation after Myectomy Procedure for Hypertrophic Cardiomyopathy

   Rochester, Minn.

   The purpose of this study is to describe the clinical impact of cardiac rehabilitation in patients who have undergone myectomy for hypertrophic cardiomyopathy.  Compare the clinical outcomes of patients who have attended cardiac rehab with those who have not attended after myectomy for hypertrophic cardiomyopathy. 

3. Prediction of Chronic Pacemaker/ICD Threshold by Increased Pulse Width Duration Pacing

   Scottsdale/Phoenix, Ariz.

   The aim of this study is to evaluate the relation of the acute pacing threshold (volts at ‘x’ pulse width) to the chronic pacing threshold of a pacemaker/ICD lead by studying the threshold during implantation at different pulse widths (eg. Twice of ‘x’, Three times of ‘x’).  

4. A Study to Assess Measurements in Cardiomyopathy Patients Using Software for Multi-level Reconstruction of Three Dimensional Transesophageal Echocardiography (TEE) or Transthoracic Echocardiography (TTE) Images

   Rochester, Minn.

   The purpose of this study is to utilize three dimensional (3D) transesophageal echocardiography (TEE) or 3D transthoracic echocardiography (TTE) to measure various mitral chordal, annular, and leaflet measurements and LV size to better understand the mechanism of regurgitation in patients with FMR.

5. Molecular Analysis of Blood for the Detection of Cardiovascular Pathogens

   Rochester, Minn.

   The purpose of this study is to test whether metagenomic shotgun sequencing can identify pathogens causing cardiovascular infections such as infective endocarditis or myocarditis.

6. 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.

    

7. A Study of Autoimmune Functions in Patients with Myocarditis

   Jacksonville, Fla.

   The purpose of this research is to study immune cells called T cells and monocytes (types of blood cells that fight infection and can also cause autoimmune disease) that may damage heart tissue during myocarditis (inflammation of the heart muscle). Cytokines (proteins that send signals between cells) found in the blood will be studied for their effects on blood immune cells to better understand how they can lead to heart failure during and after myocarditis.

8. A Study to Assess Frailty and Its Impact on Patients with Pulmonary Hypertension

   Rochester, Minn.

   The purpose of this study is to evaluate the prevalence and effect of frailty in patients referred to pulmonary hypertension (PH) clinic at our institution.

9. Analysis of Outcomes of Left Cardiac Sympathetic Denervation in Arrhythmia Syndromes and Cardiomyopathies

   Rochester, Minn.

   The purpose of this study is to collect and review the Mayo Clinic experience with left cardiac sympathetic denervation (LCSD) in patients with heritable arrhythmias syndromes or refractory ventricular arrhythmias beginning in 2000.

10. Hypoplastic Left Heart Syndrome: Validating Functional Parameters and Novel Echocardiographic Imaging Strategies for Evaluation of Functionally Single Right Ventricular Performance using Previously Recorded Studies

    Rochester, Minn.

    The purpose of this study is to validate novel echocardiographic parameters and algorithms to quantitatively evaluate right ventricular function in patients with Hypoplastic Left Heart Syndrome (HLHS) by applying these methods to previously acquired echocardiographic examinations.
