A quantitative characterization of vortex flow as turbulence and energy may offer a novel index of left ventricle (LV) dysfunction not available in conventional indexes. In this work we propose a novel method based on finite element interpolations to obtain a 3D quantitative maps of vorticity, helicity density, kinetic energy, and energy loss derived from 4D-flow data sets of the LV.  This new method may offer a novel index of LV dysfunction, permitting identify the vortex ring and the magnitude of turbulence values not available in conventional indexes. In future work we pretend validate clinically our method with patient data.
