Quantification Of Local Hemodynamic Alterations Caused By Virtual Implantation Of Three Commercially-Available Stents For The Treatment Of Aortic Coarctation, Sung Kwon
Master's Theses (2009 -)
Patients with coarctation of the aorta (CoA) are prone to morbidity including atherosclerotic plaque that has been shown to correlate with altered wall shear stress (WSS) in the descending thoracic aorta (dAo). We created the first patient-specific computational fluid dynamics (CFD) model of a CoA patient treated by Palmaz stenting, and compared resulting WSS distributions to those from virtual implantation of the NumedCP and GenesisXD stents also commonly used for CoA. CFD models were created from magnetic resonance, fluoroscopy and blood pressure (BP) data. Simulations incorporated vessel deformation, downstream vascular resistance and compliance to match measured data and generate blood ...
