Abstract
A process is provided for installing mitral valves in their anatomical space by attaching cords to an artificial stent. A new valve to be implanted, having a human or an animal nature, is subjected to a preparation which includes isolating any other tissue of the donor, to be subsequently sutured both to the periphery of the valvular zone and to the base of the stents forming the sub-valvular zone, and finally covering such zones with an anti-rejecting prosthetic material. The formation of the stents can be totally artificial, in which case the tendinous cords which activate the valvules of the valve are fixed to stents made only and exclusively from a material immune to rejection. Such cords are attached to a biological body which is subsequently covered, by the suture, with an immune material.
