Beschreibung
Zusammenfassung:	Disclosed are a prosthetic valve and a transcatheter prosthetic valve replacement system. The prosthetic valve comprises a valve support, a positioning frame, and a connecting piece. A first end of the connecting piece is connected to the positioning frame, and a second end is connected to the valve support. The valve support and the positioning frame both have a radial-compression conveyed state and a radial-expansion implanted state. When the positioning frame is in the implanted state, a positioning space can be formed around a primary valve leaflet. At least one portion of the valve support is adapted to enter the positioning space when the positioning frame is in the implanted state and to drive the connecting piece to be switched to a bending state. The valve support and the positioning frame can be positioned by means of the connecting piece in a bending state. The valve support and the positioning frame of the prosthetic valve are connected by means of the connecting piece. In the process of the valve
