From: Pulmonary artery blood flow dynamics in chronic thromboembolic pulmonary hypertension
Pulmonary blood flow dynamics before and after PEA. Pulmonary flow velocity (a), wall shear stress (b), oscillatory shear index (c), and blood stagnation volume (d) were simulated using CFD in the pulmonary arteries of patients in comparison of before and after PEA. Stagnation was defined as a flow velocity < 0.01 m/s. Data are presented as median (interquartile range). Cross indicates mean. The numbers in each box plot indicate the sample size for each group. *p < 0.05 compared to before PEA; ns, not significant; PEA, pulmonary endarterectomy.
