Figure 9. ‘Thrombogenic footprint’ comparison of the Innovia Composite valve to the Aortech PU and Carpentier-Edwards Perimount Magna tissue valves.
In forward flow, the advantage goes to the Innovia valve, which was designed for maximum flexibility, while in regurgitant flow the advantage goes to the Aortech valve, which was designed for greater ‘wash-out’ flow.
HSD: Hemodynamic shearing device; FF: Forward flow; RF: Regurgitant flow.
