1. A cardiac-valve prosthesis adapted for percutaneous implantation, the prosthesis comprising:

  • an armature adapted for deployment in a radially expanded implantation position, the armature including a support portion and an anchor portion, which are substantially axially coextensive with respect to one another, the anchor portion and the support portion adapted to assume independent radially expanded configurations when the armature is in the radially expanded implantation position; and

    a plurality of leaflets coupled to the support portion, which can be deployed with the armature in the implantation position, wherein the leaflets define, in the implantation position, a flow duct;

    wherein the anchor portion can be deployed to enable anchorage of the cardiac-valve prosthesis at an implantation site.
