Abstract

A prosthetic heart valve includes a valve frame (2), on which a plurality of valve leaflets (8) are fixed, and a fastening area for fastening in a blood vessel, which axially adjoins the valve frame (2). A stabilizing ring (14) is arranged in the fastening area. The stabilizing ring (14) defines a predetermined shape and a predetermined diameter of the fastening area and has at least one predetermined expansion point (22), whereby it is possible to expand the stabilizing ring (14) by an action of radial force on an inner circumference.
