Below are current clinical trials.

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

1. A Study to Assess Virtual Reality As Anesthesia Adjunct During Electrophysiology Lab Procedures

   Jacksonville, Fla.

   The purpose of this study is to evaluate the use of virtual reality (VR) technology as adjunct to routine anesthesia care for patients undergoing electrophysiology (EP) procedures.

2. 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. 

3. BoxX-NoAF Clinical Trial

   Rochester, Minn.

   Post Operative Atrial Fibrillation (POAF) is the most common complication of cardiac surgery. POAF incidence can exceed 50% depending on the patient baseline characteristics and surgery type. Patients with POAF tend to have worse acute and long-term clinical outcomes. BoxX-NoAF is a randomized trial to evaluate if prophylactic ablation and exclusion of the Left Atrial Appendage at the time of other routine cardiac surgery can reduce the incidence of post operative AF and clinical AF during long term follow up in patients who have not yet developed AF but are at risk.

4. VDI’s Ultra-High Frequency Electrocardiogram (UHF-ECG) For The Diagnosis Of Ventricular Electrical Dyssynchrony (VED)

   Rochester, Minn.

   The purpose of this study is to demonstrate the safety and effectiveness of the VDI UHF-ECG System in the diagnosis of VED when compared to the 12-lead ECG in patients with bradycardia and heart failure indicated for pacemaker implantation.

5. STAR Trial (Siegel Transcatheter Aortic Valve Replacement In Patients With Symptomatic Severe Aortic Stenosis)

   Jacksonville, Fla., Rochester, Minn.

   To evaluate the safety and efficacy of Siegel™ TAVR System in the treatment of subjects with symptomatic severe native aortic stenosis.

6. Spontaneous Coronary Artery Dissection: Case Review

   Rochester, Minn.

   Spontaneous coronary artery dissection (SCAD) is uncommon but important cause of acute coronary syndrome and sudden cardiac death. There is very little data exists in regards to patient clinical characteristics, risk factors, treatment and outcomes. Our objective is to prospectively assess long term outcomes. 

7. Patient-Specific Induced Pluripotent Stem Cell Models for Heritable Channelopathies and Cardiomyopathies

   Rochester, Minn.

   The purpose of this study is to derive and characterize patient-specific disease models for sudden death-predisposing heritable channelopathies and cardiomyopathies using iPS-cell technology.  It is hoped that the molecular, cellular, and electrophysiological phenotypes of these in-vitro disease models will further elucidate the pathophysiologic mechanisms underlying these sudden death-associated conditions.

8. 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.

9. A Study of In Vitro Mapping of Cardiac Tissue Obtained from Patients with Refractory Arrhythmias who Underwent Heart Transplant or Replacement with Mechanical Heart

   Rochester, Minn.

   The purpose of this study is to obtain electro-anatomic maps of human myocardium in sinus rhythm and ventricular arrhythmias to identify activation patterns, identify and perform tissue ablation at targeted sites of interest that could play an important trigger for development of arrhythmias, and to perform histologic analysis of the myocardial tissue to identify triggers and/or targets for therapies to terminate ventricular arrhythmias.

10. A Study of Ticagrelor in the Upstream Setting for Non-ST-Segment Elevation Myocardial Infarction

    Jacksonville, Fla.

    The purpose of this study is to establish a registry that will address the data gap regarding the course of NSTEMI (Non-ST-Elevation Myocardial Infarction) between ED (Emergency Department) arrival and diagnostic angiography in detail, by characterizing and following the ED and peri-ED use of advanced OAP (Oral Anti-Platelet) agents. In addition to exploring ED treatment patterns and success of both ischemic and bleeding risk stratification prior to definition of the coronary anatomy, data generated via the UPSTREAM registry will allow plausible attribution of ischemic and bleeding outcomes to pre-catheterization antiplatelet therapy in the management of NSTEMI. This registry further seeks to demonstrate that contemporary use of upstream ticagrelor is associated with an economically-sound utilization of hospital resources, and smooth transition of care into the outpatient, secondary prevention setting for the first 30 days after hospitalization. Finally, it will allow characterization of patient selection factors and processes for ticagrelor vs alternative OAP agents, carrying out that descriptive comparison through discharge. Patients transferred in to an UPSTREAM hospital are eligible for inclusion, but the timing for OAP agent administration and diagnostic catheterization begin with ED care at the first hospital.
