Abstract:
A prosthetic heart valve includes a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and leaflets attached to the cuff between a first location and a second location distal to the first location in a flow direction. The stent may include struts shaped to form a plurality of cells connected to one another in annular rows around the stent. The cuff may have top and bottom edges and may occupy a first group of the cells, such that cells above the top edge are open cells at least partially devoid of the cuff. The cuff may have a landing zone extending at least one-third of a length of the stent in the flow direction between the bottom edge of the cuff and a proximal end of a most proximal cell of the open cells when the stent is in an expanded use condition.
