Abstract: A transcatheter valve prosthesis includes a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes at least one axial frame member. The transcatheter valve prosthesis includes at least one outflow marker positioned on the at least one axial frame member. The transcatheter heart valve prosthesis may include inflow markers positioned within the inflow portion of the stent. The transcatheter heart valve prosthesis may include two outflow markers disposed on axial frame members and being circumferentially and longitudinally offset from each other. The markers are configured to aid in axial and circumferential aligned of the transcatheter heart valve prosthesis within a native heart valve.

Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.
