Longitudinal Evolution of Pulmonary Artery Wall Shear Stress in a Swine Model of Pulmonary Artery Stenosis and Stent Interventions

Ryan Pewowaruk, Luke Lamers, Alejandro Roldán-AlzateUniversity of Wisconsin. United States Annals of Biomedical EngineeringAnn Biomed Eng 2021; 49: 1477-1492DOI: 10.1007/s10439-020-02696-6 AbstractBranch pulmonary artery stenosis (PAS) commonly occurs in congenital heart disease and it has previously been hypothesized that in branch PAS the pulmonary arteries (PAs) remodel their lumen diameter to maintain constant wall shear stress (WSS).
