1. A transcatheter valve prosthesis comprising:
a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve, wherein the stent comprises an inflow portion, an outflow portion, and a plurality of axial frame members connecting the inflow portion to the outflow portion, wherein the plurality of axial frame members comprises a plurality of commissure posts and a plurality of axial struts;
a first outflow marker positioned on a first commissure post of the plurality of commissure posts, wherein only the first commissure post of the plurality of commissure posts includes a marker disposed thereon and the first outflow marker is the only marker on the first commissure post; and
a second outflow marker positioned on a first axial strut of the plurality of axial struts, the first axial strut being adjacent to the first commissure post, wherein only the first axial strut of the plurality of axial struts includes a marker disposed thereon and the second outflow marker is the only marker on the first axial strut,
wherein one of the first outflow marker and the second outflow marker is positioned closer to an outflow end of the stent relative to the other of the first outflow marker and the second outflow marker,
wherein the first outflow marker and the second outflow mater marker are visible relative to the stent in one or more images captured during delivery and deployment of the stent, and
wherein the first outflow marker and the second outflow marker are positioned such that, in an image plane parallel to an annulus of the native heart valve and bisecting a right coronary cusp of the native heart valve, if the first outflow marker and the second outflow marker appear with no radial offset, the transcatheter valve prosthesis is properly rotationally aligned.
