A heart valve prosthesis can have a valve anchor with at least one U-shaped member extending about a longitudinal axis of the valve anchor. The U-shaped member can have a peak portion and a base portion. The peak portion can have an engagement structure that allows a surgeon to engage the valve anchor with a delivery device and manipulate a position of the valve anchor in situ in order to achieve optimal placement of the prosthesis at a target site within a patient.

Heart valve prosthesis

A replacement heart valve prosthesis can be delivered to or within an existing prosthesis through a valve-in-valve delivery procedure. The existing prosthesis can be a prosthetic heart valve or other device that is implanted at a target site, such as an aortic or mitral valve of the heart. The methods provided herein can allow a surgeon to position a replacement prosthesis within or adjacent to an existing prosthesis and permit the replacement prosthesis to expand into engagement against the existing prosthesis. Thereafter, the surgeon can adjust components of the replacement prosthesis, including the position of separate anchor and frame components in order to ensure accurate and secure placement of the replacement prosthesis at the target site.
