A percutaneous prosthetic heart valve (100, 600), comprising: an expandable valve frame (102, 402, 502, 602) including valve frame members (105, 405, 450, 505, 550); a valve leaflet (132, 632) coupled to the valve frame (102, 402, 502, 602); and an expandable stent anchoring frame (104, 204, 304, 604) coupled to the valve frame (102, 402, 502, 602) including stent frame members (106, 206, 306) defining a first portion (108, 308, 608) and a second portion (110, 210, 310, 610) having greater flexibility than the first portion (108, 308, 608), where the first portion (108, 308, 608) and the valve frame (102, 402, 502, 602) define a length, and where the stent frame members (106, 206, 306) and the valve frame members (105, 405, 450, 505, 550) along the length provide a contiguous surface over which a delivery device (662, 762) can repeatedly slide over the length in its entirety in two longitudinal directions when the first portion (108, 308, 608) and the valve frame (102, 402, 502, 602) are in a partially expanded state during delivery from the delivery device (662, 762), characterized in that the stent frame members (106, 206, 306) are annular stent frame members (106, 206, 306), having apexes (114, 314) and connectors (112, 312) coupling the annular stent frame members (106, 206, 306), where in the first portion (108, 308, 608) each apex (114, 314) formed by the annular frame member is connected by a connector (112, 312) to an apex of an adjacent stent frame member (106, 206, 306) and in the second portion (110, 210, 310, 610) not every apex formed by the annular frame member is connected to an apex of an adjacent stent frame member. an expandable valve frame (102, 402, 502, 602) including valve frame members (105, 405, 450, 505, 550); a valve leaflet (132, 632) coupled to the valve frame (102, 402, 502, 602); and an expandable stent anchoring frame (104, 204, 304, 604) coupled to the valve frame (102, 402, 502, 602) including stent frame members (106, 206, 306) defining a first portion (108, 308, 608) and a second portion (110, 210, 310, 610) having greater flexibility than the first portion (108, 308, 608), where the first portion (108, 308, 608) and the valve frame (102, 402, 502, 602) define a length, and where the stent frame members (106, 206, 306) and the valve frame members (105, 405, 450, 505, 550) along the length provide a contiguous surface over which a delivery device (662, 762) can repeatedly slide over the length in its entirety in two longitudinal directions when the first portion (108, 308, 608) and the valve frame (102, 402, 502, 602) are in a partially expanded state during delivery from the delivery device (662, 762), characterized in that the stent frame members (106, 206, 306) are annular stent frame members (106, 206, 306), having apexes (114, 314) and connectors (112, 312) coupling the annular stent frame members (106, 206, 306), where in the first portion (108, 308, 608) each apex (114, 314) formed by the annular frame member is connected by a connector (112, 312) to an apex of an adjacent stent frame member (106, 206, 306) and in the second portion (110, 210, 310, 610) not every apex formed by the annular frame member is connected to an apex of an adjacent stent frame member.
