Abstract: Methods for rotationally aligning transcatheter heart valve prosthesis within a native heart valve include percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve, wherein the transcatheter heart valve prosthesis includes at least one imaging marker, receiving a cusp overlap viewing angle image and/or a coronary overlap viewing angle image of the transcatheter heart valve prosthesis within the native heart valve, determining, based on the cusp overlap viewing angle image and/or the coronary overlap viewing angle image and the at least one imaging marker, whether the transcatheter heart valve prosthesis is in a desired rotational orientation, if the at least one imaging marker in the cusp overlap viewing angle image and/or the coronary overlap viewing angle indicates that the transcatheter heart valve prosthesis is not in the desired rotational orientation, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rotational orientation.
