title = "Effect of suture density on the dynamic behavior of the bioprosthetic heart valve: A numerical simulation study",
abstract = "This paper constructs the bioprosthetic valve leaflets' parametric model using computer aided design.A series of accurate parameters of the bioproshtetic heart valve, such as radius of the sutural ring, height of the supporting stent and inclination of the supporting stent are determined. Numerical simulation is used to determine the effect of different shape designs and suture density on the mechanical performance of the bioprosthetic valve leaflet. The dynamic behavior of the valve during diastolic phase is analyzed. The finite element analysis results show that the stress distribution of the ellipsoidal leaflet valve is good. The ellipsoidal leaflet valve has the following advantages over the cylindrical leaflet valve: lower peak von Mises-stress, smaller stress concentration area and relatively uniform stress distribution. The suture density also has a significant effect on the dynamic behavior of the valve as it can act to reduce the pressure and improve the stress distribution. It was found that the influence of suture density in the stress of the leaflet differs on the basis of different geometries considered in the model. The degree of influence of the suture density in the bioprosthetic heart valve may also be dependent on the geometries of the valves. This indicates the need to account for the attachment edge, when manufacturing such bioproshetic heart valves for long term durability. Further research is required to assess the effect of suture density on the bioprosthetic heart valve models.",
