Reynolds shear stress for textile prosthetic heart valves in relation to fabric design

Abstract: The most widely implanted prosthetic heart valves are either mechanical or bioprosthetic. While the former suffers from thrombotic risks, the latter suffers from a lack of durability. Textile valves, alternatively, can be designed with durability and to exhibit hemodynamics similar to the native valve, lowering the risk for thrombosis. Deviations from native valve hemodynamics can result in an increased Reynolds Shear Stress (RSS), which has the potential to instigate hemolysis or shear-induced thrombosis. Thi… Show more

“…Based on this premise, multiple studies focused on developing polymeric heart valves[4, 15, 39] (PHVs) made out of homogeneous materials or more recently as inhomogeneous textile heart valves (THVs) [1]. In another study we demonstrated that a linear low density polyurethane (LLDPE) PHV enhanced with hyaluronic acid would provide good hemocompatibility for prosthetic heart valves [26].…”

“…Despite the fact that the maximum RSS of the bileaflet valve is almost identical to that of the trileaflet valve, the bileaflet prosthesis presents a higher overall RSS level in the downstream conduit. This could be attributed to the high leaflet profile of the bileaflet design (Bark et al, 2016).…”

“…This is then supported by the formation of vortex structures at the end of the three cusps, observed in the PIV experiment. Bark et al (2016), observed the flow fields generated by different textile fabrication techniques through time-resolved PIV technique. Mokhtar et al (2016), performed the PIV experiment to analyze the effect of stent placement on the flow pattern, velocity, and pressure with hope to reduce the size of the aneurysm issue.…”
