From: Pulmonary artery blood flow dynamics in chronic thromboembolic pulmonary hypertension
Work process of analysis using computational fluid dynamics. 3D geometries of patient-specific pulmonary arteries in control individuals and patients with CTEPH were generated using computed tomography pulmonary angiography before and after PEA or BPA. After the tetrahedral meshes and boundary-fitted prism layers were created, a CFD simulation was performed to reproduce patient-specific pulmonary artery flow dynamics. CTEPH, chronic thromboembolic pulmonary hypertension; PEA, pulmonary endarterectomy; BPA, balloon pulmonary angioplasty. CT, computed tomography; DICOM, digital imaging and communications in medicine; STL, stereolithography; WSS, wall shear stress; OSI, oscillatory shear index.
