Abstract: A transcatheter valve prosthesis includes a balloon expandable stent and a prosthetic valve. An inflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost inflow side openings and endmost inflow crowns are formed at the inflow end of the stent and the inflow end of the stent has a total of twelve endmost inflow crowns. An outflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost outflow crowns are formed at the outflow end of the stent and the outflow end of the stent has a total of six endmost outflow crowns. The prosthetic valve is disposed within and secured to the stent.

Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve disposed within the stent. The stent is balloon expandable and includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. A diameter of an inflow end of the transcatheter valve prosthesis is greater than a diameter of an outflow end of the transcatheter valve prosthesis. The transcatheter valve prosthesis has a tapered profile along an entire height thereof when in the stent is in the expanded configuration. The inflow end of the transcatheter valve prosthesis is configured to sit within and contact an aortic annulus of the native aortic valve and the outflow end of the transcatheter valve prosthesis being configured to float within an ascending aorta without contacting the ascending aorta due to the tapered profile of the transcatheter valve prosthesis.
