1. A therapeutic heart valve system for implantation at a native heart valve of a patient's heart, the system comprising:
a prosthetic device configured to be implanted at the native heart valve, the prosthetic device comprising a spine and a prosthetic valve with a plurality of prosthetic leaflets configured to open and close during the cardiac cycle; and
a support comprising an elongated shaft, the support configured to be coupled to the spine via a connection system such that the support, when coupled to the spine, maintains the prosthetic device at the native heart valve,
wherein the prosthetic valve comprises proximal and distal rings coupled to the spine via a plurality of tethers, and an outer skirt forming a channel extending between the proximal and distal rings, and wherein the plurality of prosthetic leaflets are mounted within the channel of the prosthetic valve.
