For implantation outstanding ratio of orifice-to -annulus is taken with efficiency and safety. The cuff size is minimized by sewing cuff assembly that maximizes orifice area. The clinical considerations being the repeated replacements to be reduced in growing heart, fits in the position where the bileaflet valve will not. The leaflet lock-up chances are reduced by titanium stiffening ring. For valve related events the clinical record and safety is provided. It can be applied in small Aortic annulus and placement of intra or supra-annular is allowed by the design.
