Aortic valve regurgitation

Displaying 6 studies

  • Comparison of Echocardiographic Parameters Between Acute and Chronic Severe Aortic Regurgitation Rochester, MN

    The purpose of this study is to compare echocardiographic between acute and chronic severe AR patients at baseline and after surgical aortic valve replacement.

  • Non-Invasive Assessment of Valvular Regurgitation Rochester, MN

    Measure by Doppler color automated integration cardiac stroke volumes and calculate regurgitant volume.

  • A Study of Strain Echocardiography in Assessment of Valvular Heart Disease Rochester, MN

    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.

  • Usefulness of Color M-mode for Vena Contracta of Aortic Regurgitation in Patients with Left Ventricular Assist Devices Rochester, MN

    The purpose of this study is to assess the feasibility of color M mode and standard vena contracta measurements and compare these to novel measurements of aortic regurgitation in left ventricular assist devices (LVADs).

  • Assessment of Advanced Magnetic Resonance Imaging in Heart Rochester, MN

    The purpose of this study is to continue the evaluation of non-FDA approved MR equipment software and hardware for imaging the heart and associated vasculature.

  • Biomarkers in Aortic Stenosis - B.A.S.S. No Locations

    This study is being done to determine whether or not new blood test(s) can determine the severity of heart conditions. Aortic stenosis, hypertrophic cardiomyopathy, mitral regurgitation, aortic regurgitation, artificial heart valve regurgitation or stenosis, and tricuspid valve regurgitation associated with pacemaker leads are the cardiac disorders under study. The blood tests involve analysis for von Willebrand Factor antigen and activity, von Willebrand Factor multimers, and brain natriuretic peptide (BNP) levels. The results of the blood tests will be compared to the information from the clinically-indicated echocardiogram and one blood test compared to another.
