Quantitative Doppler echocardiography [PDF]
BJA Education, 2016 ### Key points Echocardiography provides information regarding volumes [e.g. stroke volume (SV), ejection fraction], flows [e.g. cardiac output (CO), shunt fractions], and pressures (e.g. gradients across valves). As the only directly measurable variables are length (using 2D imaging) and velocity (using spectral Doppler), quantitative haemodynamic ...

Quantification of left ventricular longitudinal strain, strain rate, velocity and displacement in healthy horses by 2-dimensional speckle tracking [PDF]
, 2011 Background: The quantification of equine left ventricular (LV) function is generally limited to short-axis M-mode measurements. However, LV deformation is 3-dimensional (3D) and consists of longitudinal shortening, circumferential shortening, and radial ...

Echocardiography during submaximal isometric exercise in children with repaired coarctation of the aorta compared with controls [PDF]
, 2019 Objective Patients with repaired coarctation (RCoA) remain at higher risk of cardiac dysfunction, initially often only detected during exercise. In this study, haemodynamics of isometric handgrip (HG) and bicycle ergometry (BE) were compared in patients ...

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]
, 2019 Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]
, 2009 In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,
