Fig. 4

Illustration of blood flow components inside the left ventricle (LV) cavity of a normal subject. (A) The 4 components of the LV end-diastolic volume (EDV) are represented using different colors: direct flow (DF) in green, retained inflow (RI) in yellow, residual volume (RV) in red and delayed ejection flow (DEF) in blue. (B) The pie chart shows the normal percentage of the 4 components of the LV EDV. (C) The graph illustrates the temporal distribution of blood kinetic energy (KE) for each of the 4 components of the LV EDV. (D) Motion of the 4 components of the LV EDV is illustrated at different times during the cardiac cycle
