Pipeline for the generation of patient-specific models and simulations in this study (Patient 2, posterior view). (A) Post-surgical CT pulmonary angiography. (B) Segmentation of the stenosed model with surface interpolation and arrow indicating stenosis on the LPA. (C,D) tetrahedral mesh (C) with curvature refinement (D). (E) Prescription of boundary conditions at the outlets (two-element Windkessel model) and at the inlet (Dirichlet condition on flow velocity); (F) CFD simulation of blood flow visualized using streamlines colored by velocity magnitude.
