Figure 1 Flow Data by Digital Particle Image Velocimetry From the Apical Long-Axis View
The Echo freeze frames represent the divergence-free velocity vector on the scan-plane, superimposed to the reconstructed Doppler representation (A). Parametric representations of steady streaming field with superimposed velocity vectors (arrows) and the steady streaming in-plane streamlines along the divergence-free velocity field (B). The pulsatile strength field with superimposed pulsatile in-plane streamlines (C). LVOT = left ventricular outflow tract; MV = mitral valve. See Online Video 1.
