1. A prosthetic valve delivery system, comprising:
a catheter assembly having a central axis and being adapted to retain a prosthetic valve in a collapsed state; and
a plurality of markers integrated with the catheter assembly at a-marker locations radially offset from the central axis, each of the marker locations being offset from a next adjacent marker location by an angular distance about the central axis, each of the markers having a contrasting radiopacity to the radiopacity of a material of the catheter assembly circumferentially aligned with the marker locations, wherein each of the marker locations is positioned to be angularly aligned about the central axis with a respective commissure attachment feature of the prosthetic valve when the prosthetic valve is retained in the catheter assembly.
