Comparison of hemodynamic parameters across the cohort (n = 7 PAH subjects). a Area-averaged velocity at the inlet over a cardiac cycle. b Velocity distribution at inlet, main body, and outlet. c Cross-sectional area reduction at the outlet compared to the inlet (P < 0.0001). Data are presented as mean ± SD. Note: Asteriks denote statistical significance, with * P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
