Claim 9:
10. A method for rotationally aligning a transcatheter heart valve prosthesis within a native heart valve, the method comprising:
percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve, wherein the transcatheter heart valve prosthesis comprises three imaging markers with each imaging marker substantially axially aligned with a commissure of a valve structure of the transcatheter valve prosthesis;
receiving a cusp overlap viewing angle image of the transcatheter heart valve prosthesis within the native heart valve;
determining whether the transcatheter heart valve prosthesis is in a desired rotational orientation by determining, based on the cusp overlap viewing angle image and the three imaging markers, whether two of the imaging markers are substantially aligned on a left side of the cusp overlap viewing angle image; and
if the two imaging markers in the cusp overlap viewing angle image are not substantially aligned on the left side of the cusp overlap viewing angle, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rotational orientation.
