Figure 7. Linear regression analysis between the changes in primary catheterization hemodynamics of 4‐dimensional–flow magnetic resonance imaging derived individual flow components in the right ventricle.

Changes in mean pulmonary arterial pressure (mPAP) were not associated with the change in direct flow (A) and residual volume (B). Similarly, change in the pulmonary vascular resistance index (PVRi) was not associated with direct flow (A) and residual volume (B). WU indicates Wood unit.
