摘要:
A frame structure for a collapsible and re-expandable prosthetic heart valve. The frame structure includes an annular annulus portion that is configured for implanting in or near a patients native heart valve annulus. This annulus portion of the frame structure may include a plurality of annularly spaced commissure post structures interconnected by connecting structures. The commissure post structures may be more resistant to annular collapse than the connecting structures. In the case of a prosthetic aortic valve, the frame structure may also include an annular aortic portion. The aortic portion may include a plurality of attachment points (for tethers) closest to the annulus portion. Such attachment points and tethers can facilitate re-collapse of a partly deployed valve in the event of a need to reposition or remove the valve.
