A valved stent for a patient heart, comprising: a stent supporting a cloth structure together forming the valved stent, the valved stent further comprising: an upper mounting portion having an upper side and lower side and including a plurality of hooks extending downwardly from the lower side whereby the implantable valve is mounted to the heart when heart tissue is captured between the hooks and the lower side; and a lower valved portion extending downwardly from the upper mounting portion, the lower valved portion including a check valve disposed inside the cylindrical lower portion that allows downward flow of blood and checks upward flow of blood; characterized by a lower mounting portion; a plurality of support members that each have an upper portion and a lower vertical portion; a plurality of metal arcs that are each coupled to two of the upper portions of the support members; and a metal mesh that is joined to the lower vertical portions of the support members to define the lower portion of the stent having a substantially cylindrical shape; wherein the cloth structure includes: an upper portion that is disposed above and supported by the metal arcs; and a substantially cylindrical lower portion that is supported by and radially inside the metal mesh; wherein the number of the plurality of support members, metal arcs and hooks is N with the N metal arcs defining a maximum radial dimension that is in a range of 32 to 52 millimeters and the plurality of N hooks that are each coupled to and extend downwardly from one of the support members, wherein a vertical spacing between the metal arcs and the hooks is configurable to accommodate variations in heart tissue geometry that is captured between the metal arcs and the hooks. an upper mounting portion having an upper side and lower side and including a plurality of hooks extending downwardly from the lower side whereby the implantable valve is mounted to the heart when heart tissue is captured between the hooks and the lower side; and a lower valved portion extending downwardly from the upper mounting portion, the lower valved portion including a check valve disposed inside the cylindrical lower portion that allows downward flow of blood and checks upward flow of blood; characterized by a lower mounting portion; a plurality of support members that each have an upper portion and a lower vertical portion; a plurality of metal arcs that are each coupled to two of the upper portions of the support members; and a metal mesh that is joined to the lower vertical portions of the support members to define the lower portion of the stent having a substantially cylindrical shape; wherein the cloth structure includes: an upper portion that is disposed above and supported by the metal arcs; and a substantially cylindrical lower portion that is supported by and radially inside the metal mesh; wherein the number of the plurality of support members, metal arcs and hooks is N with the N metal arcs defining a maximum radial dimension that is in a range of 32 to 52 millimeters and the plurality of N hooks that are each coupled to and extend downwardly from one of the support members, wherein a vertical spacing between the metal arcs and the hooks is configurable to accommodate variations in heart tissue geometry that is captured between the metal arcs and the hooks. an upper portion that is disposed above and supported by the metal arcs; and a substantially cylindrical lower portion that is supported by and radially inside the metal mesh; wherein the number of the plurality of support members, metal arcs and hooks is N with the N metal arcs defining a maximum radial dimension that is in a range of 32 to 52 millimeters and the plurality of N hooks that are each coupled to and extend downwardly from one of the support members, wherein a vertical spacing between the metal arcs and the hooks is configurable to accommodate variations in heart tissue geometry that is captured between the metal arcs and the hooks.
