Dilated Cardiomyopathy (DCM) is a disease of the heart muscle characterized by the enlargement of the left ventricle and systolic/ diastolic dysfunction. Cardiac Magnetic resonance (CMR) is the gold standard to measure cardiac function using b-SSFP CINE images1. However, hemodynamic parameters within the ventricles have received less attention. In this work, we present a method that allows a comprehensive assessment of different flow parameters in the left ventricle of DCM patients using a finite element framework over 4D flow data sets.
