Time-averaged WSS (TAWSS) distribution in the pulmonary artery tree of a representative PAH subject (Case P7). a, d TAWSS across the extensive pulmonary artery tree (up to 6 th-generation branches), main, and branches in PAH subject. b Anterior views of proximal arteries. c TAWSS at inlet vs. outlet. d Comparison of TAWSS in main vs. branch segments. Note: Asteriks denote statistical significance, with * P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
