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.

Abstract: A skirt-reinforcement member for supporting or reinforcing an unsupported portion of a skirt that spans across a side opening of a stent or frame of a valve prosthesis. The skirt-reinforcement member is configured to prevent billowing of the skirt material that spans across the side opening of the inner frame of the valve prosthesis, as such billowing may undesirably result in contact between the skirt and leaflets of the valve prosthesis after the valve prosthesis is deployed in situ.

Abstract: A transcatheter heart valve prosthesis includes an annular stent, a valve structure including a plurality of leaflets positioned within and coupled to the stent, an inner skirt coupled to an interior surface of the stent, an exterior skirt coupled to an exterior surface of the stent, and a radiopaque marker is secured between the interior skirt and the exterior skirt.
