Left Ventricular Flow Analysis: Recent Advances in Numerical Methods and Applications in Cardiac Ultrasound

Figure 2

Simulation of a filling flow jet entering the left ventricle (top panels) and flow vortex in the inflow region along with an ejection jet in the left ventricular outflow tract (bottom panels) by using the weighted least-squares finite element method (WLSFEM), without the assimilation of particle image velocimetry (PIV) data (left panels) and with assimilated data (right panels). Blue, green, and red colors indicate low, mid, and high flow velocities, respectively.
