Fig. 3.
Hemodynamic wall shear stress (WSS) measured in the proximal pulmonary arteries. A–C: plots depicting the variability in maximum systolic WSS (WSSmax) between all considered groups revealed significantly decreased WSSmax between pulmonary arterial hypertension (PAH) and control group in each age group. Additionally, there was a difference in time-averaged WSS (WSSTA) between age-specific groups in respective PAH and control groups when the branch pulmonary arteries were considered. D–F: identical plots for WSSTA.
