    摘要: A prosthetic heart valve (200) may include a stent (202) with a plurality of cells (212a-d) arranged in circumferential rows and a cuff (206) attached to the stent. A leaflet attachment panel (260) may be attached to and span a portion of one of the cells. A leaflet (208) having a belly (210) may be mounted to the leaflet attachment panel. The leaflet attachment panel may not be integral with the stent body. A reduced overlap area may be defined between a proximal end of the stent body and a proximalmost point of attachment of the leaflet belly to the cuff. The reduced overlap area may have a size dependent upon the circumferential row of cells the leaflet attachment panel is attached to and a position of the portion of the leaflet attachment panel to which the leaflet is mounted. Alternately, the leaflet may be attached directly to the stent.

    摘要: 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.
