Claim 16:
17. 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 a single 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 single imaging marker, whether the single imaging marker is on a right side of the cusp overlap viewing angle image and within a zone of confidence; and
if the single imaging marker in the cusp overlap viewing angle image is not on the right side of the cusp overlap viewing angle and within the zone of confidence, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rotational orientation.
