Abstract
A prosthetic mitral valve may include a collapsible stent including a plurality of struts, a plurality of cells arranged in circumferential rows, the circumferential rows including a first row at an outflow end of the stent and a second row at an inflow end of the stent, and a plurality of strut intersections where at least two of the struts connect to one another. A cuff is attached to the stent. A prosthetic valve assembly is adapted to allow blood to flow in only one direction through the valve. The prosthetic valve assembly includes a first prosthetic leaflet having a first end attached directly to a first one of the strut intersections, and a second prosthetic leaflet having a first end attached directly to the first strut intersection. The first strut intersection is partially formed of one of the struts of one of the cells in the first row.
