Background 4D flow CMR analysis of right ventricular (RV) diastolic inflow has demonstrated vortical formations at tips of the tricuspid valve during the deceleration phase of early filling (E wave) (Figure 1). Vorticity can measure the rotation of these vortices and may represent a novel way to assess RV diastolic function. We aimed to determine if right heart vorticity identified right ventricular diastolic dysfunction (RVDD) in pulmonary hypertension (PH) subjects when compared to controls using 4D flow CMR. Methods
