Vahidkhah and colleagues used patient-specific geometry of the aortic root, ascending aorta, and coronary arteries to model blood flow near the aortic valve leaflets. The authors use this model to better understand flow-related permissive factors that might mediate leaflet thrombosis following valve replacement. Greater blood stasis was observed in the transcatheter valve-in-valve model compared to the surgical valve model, and no differences in blood stastis were modeled between coronary and noncoronary leaflets for the transcatheter valve.
