Abstract: A prosthetic valve has an annular frame that is radially expandable and a leaflet structure positioned within the frame. The frame has an inflow end, an outflow end, a first row of angled struts defining the outflow end, a second row of angled struts upstream of the first row of angled struts, a third row of angled struts upstream of the second row of angled struts, and a plurality of axial frame members comprising respective first ends and second ends. The first ends are connected to the second row of angled struts and the second ends are connected to the third row of angled struts. The plurality of axial frame members include a plurality of axially extending commissure supports and one or more axial posts located between any two immediately adjacent commissure supports. Each commissure support is configured to support a corresponding commissure of the leaflet structure.

Abstract: A prosthetic heart valve including a radially expandable and compressible annular frame is disclosed. The frame includes a plurality of interconnected struts defining a plurality of rows of cells arranged between an inflow end and an outflow end of the frame, the interconnected struts comprising a plurality of outflow struts defining the outflow end and a plurality of inflow struts defining the inflow end. The frame further includes a plurality of apex regions formed at the inflow end and the outflow end, each apex region curving between two angled strut portions and forming one of the outflow struts or one of the inflow struts with the two angled strut portions. Each apex region has a narrowed width and a length that extends along at least 25% of a total length of the outflow strut or inflow strut, the narrowed width smaller than a width of the two angled strut portions.

Abstract: The present disclosure relates to prosthetic valves that include information indicators which can indicate suitable information associated with a previously implanted prosthetic valve. Such information indicators can be internally formed in relatively wide support posts of mechanically expandable prosthetic valve, or can be externally formed along support posts of mechanically expandable prosthetic valve or vertical struts of balloon expandable prosthetic valves.
