First-in-Man Ultrasound Measurements of Myocardial and Vascular Viscoelasticity -- A Pilot Study
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.

Long Term Efficacy of Left Atrial Appendage Closure with the Watchman Device
Rochester, Minn.
The purpose of this study is to evaluate the number of leaks from the LA into the LAA, and the size of each.
-
Non-invasive assessment of aortic properties
Rochester, Minn.
The purpose of this study is to measure the characteristics of the walls of an enlarged aortic blood vessel using non-invasive heart echo to help predict how quickly the enlargement may develop.

Role of 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.

Role of 3D Echocardiography Volumetric Measurements in Patients with Valvular Heart Disease
Rochester, Minn.
The purpose of this study is to evaluate the severity of valvular lesions by using a new investigational imaging protocol. This new protocol includes 3D volumetric evaluation and is designed to see if such measurements are useful to be added to regular echo studies. An investigational image protocol means that the protocol is still experimental and isn’t approved by the U.S. Food and Drug Administration (FDA).

The Role of Strain Echocardiography in Assessment of Valvular Heart Disease. A Prospective Study
Rochester, Minn.
Classical echocardiographic assessment of heart valves is critical in determination of disease severity. However, echocardiography has only limited ability to predict how well an individual patient will do at time of surgery. New echocardiographic technology allows us to measure new, more refined parameters of your heart’s performance. This study is investigating whether these new parameters are better in predicting outcomes.

Transapical and Transfemoral TAVR, Two Different Patient Populations with Possible Similar Clinical and Cardiac Mechanics Outcomes
Rochester, Minn.
Compare transapical and transfemoral TAVR as regards clinical outcomes (both beneficial including improvement in heart failure class (NYHA) and reduced number of hospitalizations; and adverse including mortality and MACE.) Also, to compare cardiac mechanics’ outcomes in the short and intermediate follow up and correlate the baseline, percent change and final cardiac mechanics values with the clinical outcomes. So that this all comes down to being able to provide these information to the patients if there appeared to be a correlation between cardiac mechanics and clinical outcomes:
