Abstract:Objective To evaluate the hemodynamic changes and the shear stress characteristics of the pulmonary arteries after
bidirectional Glenn shunt (BGS) and assess the value of different oscillatory shear stress after the surgery. Methods The pulmonary
artery images of 8 congenital heart disease patients after BGS were collected using magnetic resonance imaging. The threedimensional
shear stress model and the oscillatory shear stress value were calculated by computational fluid dynamics. Results In
this study, the average oscillatory shear stress was (0.233±0.067) Pa in these 8 congenital heart disease patients. In case 7, there was
a low shear stress in the superior vena cava and the left pulmonary artery, and the lowest value of the calculated oscillatory shear
stress was 0.14 Pa. Conclusion For congenital heart disease patients after BGS, evaluating personalized shear stress model and the
mean oscillatory shear stress of pulmonary artery based on computational fluid dynamics contributes to the understanding of the
hemodynamics of the patients.
