A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent including a plurality of struts. A cuff may be coupled to the stent so that a flat, bottom edge of the cuff lies adjacent the proximal end of the stent. A pattern of stitches may be circumferentially disposed around the flat bottom edge of the cuff, the pattern of stitches alternating between stitches sewn to the cuff only and stitches sewn to both the cuff and the stent.

The illustrative embodiment comprises the sewing of fibers into a sewing substrate, which is then overmolded, to enable the manufacture of strong and lightweight articles with complex geometries.
