Figure 1.

Left: finite element mesh of a biventricular geometry reconstructed from MR images separated into 3 material regions, namely, left ventricle free wall (blue), septum (green), and right ventricle free wall (right). Right: myocardial fiber orientation are assigned using the LDRB algorithm42 with an angle +α and −α prescribed on the endocardium and epicardium, respectively. Here showing the fiber architecture for α ranging from 30° to 80° with increments of 10°, where the absolute value of the fiber angle is used as color map
