Figure 6:

A 3D model of the right ventricle shows the regional contributions to survival prediction in 256 patients with PH. The models show where reduced (red) or increased (blue) systolic motion is associated with death. This is shown by, A, the magnitude of excursion, as well as, B–D, each directional component. The right ventricle is shown in the anterior and septal views, with the left ventricle depicted as a mesh. A reduction in both longitudinal basal motion and transverse bellows contraction is associated with death, as is an increase in circumferential contraction.
