Abstract: Apparatus is provided, including: (A) a valve body (204) including a first frame (206) shaped to define a lumen therethrough, and a valve member (205) disposed within the lumen, (B) an upstream support (210), configured to be placed against an upstream surface of a native heart valve, and (C) a flexible sheet (214) that couples the upstream support to the valve body. The valve body has a compressed state in which the first frame has a first diameter, and an expanded state in which the first frame has a second diameter that is greater than the first diameter. The support includes a second frame (212) that has a compressed state, and an expanded state in which the second frame is annular, has an inner perimeter that defines an opening through the second frame, and has an outer perimeter. Other embodiments are also described.

Abstract: Apparatus for use at a native heart valve of a subject is described. For some applications, the apparatus comprises a prosthetic valve support, configured (a) to be implanted at the native valve, (b) to facilitate, at a first period, implantation at the native valve of a first prosthetic valve, and (c) to facilitate, at a second period, implantation at the native valve of a second prosthetic valve. Other embodiments are also described.

Abstract: For some applications, apparatus is provided for facilitating implantation of a prosthetic valve at a native heart valve of a subject, the apparatus comprising a prosthetic valve support, the prosthetic valve support (a) being configured to be transluminally-deliverable to the native valve and to be deployable at the native valve, and (b) comprising one or more tissue-engaging elements, configured to couple the prosthetic valve support to leaflets of the native valve without eliminating check valve functionality of the native valve. Other embodiments are also described.
