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 an inflow portion, an outflow portion, and at least one commissure post positioned at least partially in the outflow portion of the stent. The transcatheter valve prosthesis includes an inflow marker positioned within the inflow portion of the stent, the inflow marker including a first radiopaque material. The transcatheter valve prosthesis includes an outflow marker positioned on the at least one commissure post, the outflow marker including a second radiopaque material. The first radiopaque material and the second radipaque material cause the inflow marker and the outflow marker to be visible relative to the stent in one or more images captured during the installation at the implant location.

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, the two outflow markers being circumferentially and longitudinally offset from each other. The markers are configured to aid in axial and circumferential alignment of the transcatheter heart valve prosthesis within a native heart valve.
