Feasibility and Reproducibility of Systolic Right Ventricular Strain Measurement by Speckle-Tracking Echocardiography in Premature Infants

Jun 1, 2018 by in CARDIOLOGY Comments Off on Feasibility and Reproducibility of Systolic Right Ventricular Strain Measurement by Speckle-Tracking Echocardiography in Premature Infants

Background Right ventricular (RV) systolic function is an important prognostic determinant of cardiopulmonary pathologies in premature infants. Measurements of dominant RV longitudinal deformation are likely to provide a sensitive measure…

Three-Dimensional Color Doppler Echocardiographic Quantification of Tricuspid Regurgitation Orifice Area: Comparison with Conventional Two-Dimensional Measures

Jun 1, 2018 by in CARDIOLOGY Comments Off on Three-Dimensional Color Doppler Echocardiographic Quantification of Tricuspid Regurgitation Orifice Area: Comparison with Conventional Two-Dimensional Measures

Background Three-dimensional (3D) color Doppler echocardiography (CDE) provides directly measured vena contracta area (VCA). However, a large comprehensive 3D color Doppler echocardiographic study with sufficiently severe tricuspid regurgitation (TR) to…

Velocity Vector Imaging in the Measurement of Left Ventricular Myocardial Mechanics on Cardiac Magnetic Resonance Imaging: Correlations with Echocardiographically Derived Strain Values

Jun 1, 2018 by in CARDIOLOGY Comments Off on Velocity Vector Imaging in the Measurement of Left Ventricular Myocardial Mechanics on Cardiac Magnetic Resonance Imaging: Correlations with Echocardiographically Derived Strain Values

Background Regional and global function can be measured by echocardiography using speckle-tracking, a technique that has previously been validated against crystal sonomicrometry. However, the application of Velocity Vector Imaging (VVI)…

Calcification of the Mitral Valve and Annulus: Systematic Evaluation of Effects on Valve Anatomy and Function

Jun 1, 2018 by in CARDIOLOGY Comments Off on Calcification of the Mitral Valve and Annulus: Systematic Evaluation of Effects on Valve Anatomy and Function

Background Mitral annular calcification (MAC) is common in chronic kidney disease. It is associated with cardiovascular events and can cause valvular dysfunction, but it has not been systematically characterized. The…
