Why the study?
Neither bioprosthetic nor mechanical cardiac valve implants fulfill both hemodynamic and durability requirements.

Should not alter current valve selection; leaves open whether geometry-enabled stiff polymers can deliver durable anticoagulation-free performance in vivo.
A buckling-inspired double-curvature leaflet design significantly enhances the opening behavior of trileaflet polymeric valves, particularly for stiffer materials.
