Popis: The paper presents a numerical method of blood flow simulation in two geometries. The first geometry covered the ascending and descending parts of aorta and its main branches in patient with a congenital heart disease - coarctation of aorta (inborn narrowing of the descendent aorta). The second geometry used in the flow field analysis mimicked the state of the vessel after a successful percutaneous intervention and thus without pathological narrowing (virtual therapy). The blood was treated as a non-Newtonian fluid. The pulsating flow was set at the inlet to ascending aorta. The lumped model based on electrical analogy using three-element-Windkessel model was created to calculate pressure at the outlets. In the publication the fields of velocity and pressure were presented. The obtained outflow streams were modified after virtual therapy.
