Beschreibung
Zusammenfassung:	Described herein are annular frames for prosthetic heart valves that include commissure portions that are radially offset and/or are radially flexible relative to the rest of the frame. The commissure portions can extend radially outwardly from the rest of the frame such that they are positioned at a greater radius than the adjacent struts of the frame. The commissure portions can be cantilevered from the frame, such that only one axial end of the commissure portion is attached to the rest of the frame, allowing the commissure portions to flex radially inwardly and outwardly relative to the rest of the frame. Lateral arms can also couple upper ends of the commissure portions to adjacent apices to pull them in at larger diameters. The radial position of the commissure portions relative to the rest of the frame can affect the positioning of the leaflets and the effectiveness of the valve.
