Cardiovascular diseases, including heart attacks and strokes, are leading causes of mortality worldwide. A significant contributor to these conditions is the formation of blood clots obstructing blood flow to critical organs. This study looks specifically at the blood flow in the left ventricle (LV) using simulations with Finite Element Method (FEM). Computational simulations of blood flow offer valuable insights into potential risks, aiding in pre-surgical assessments. However, interpreting simulation results, often presented as ambiguous velocity fields, can be difficult. This study examines two different post-processing measurements, triple decomposition of the velocity gradient tensor and E-wave propagation index (EPI), that can turn these complexities into simpler scalar fields and values. This study confirms that both measurements are computable and most likely useful given a velocity vector field. Further studies, particularly by medical professionals, need to be done to analyse the effects of the measurements and verify its usefulness by comparison to the same measurements in real, not simulated, patients. Some specific studies are proposed to address this. With the triple decomposition implemented some basic analysis was done. High levels of shear were observed in certain areas, particularly around the papillary muscles, where strain was also present.
