Claim 0:
1. A prosthetic heart valve implant for use at a native valve of a heart of a subject, the implant configured to assume a compressed delivery state for percutaneous delivery to the heart and an expanded state for implantation at the native valve, the implant comprising:
a frame, which is shaped so as to define interconnected cells that define upstream and downstream ends of the frame and upstream and downstream openings at the upstream and the downstream ends, respectively, when the implant is in the expanded state;
a sheet, which is coupled to the frame; and
a plurality of prosthetic leaflets, configured to facilitate downstream movement of blood and to inhibit upstream movement of blood when the implant is implanted at the native valve,
wherein when the implant is in the expanded state, the frame is shaped so as to define the following longitudinal portions arranged along a central longitudinal axis of the prosthetic heart valve implant:
a mid portion that is entirely substantially cylindrical and has a diameter greater than respective diameters of the upstream and the downstream ends of the frame,
an upstream portion, extending upstream and curving radially inward from the mid portion, and
a downstream portion, extending downstream and curving radially inward from the mid portion, and

wherein a diameter of the mid portion is greater than a height of the frame between the upstream and the downstream ends of the frame.
