摘要： 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.

摘要： A heart valve prosthesis includes a downstream first axial end (6) and an upstream second axial end (8) and a stitching ring (10) extending in an arcuate manner for stitching in a blood vessel. The arcuate course of the stitching ring (10) is formed by three arcs (12) and three transition regions (14). At each end of two of the arcs (12) transition into each other. The stitching ring (10) has a movable tab (18) at at least one of the three transition regions (14). The movable tab (18) can be selectively directed toward the first axial end (6) or folded over toward the second axial end (8).

摘要： A heart valve prosthesis includes a valve frame (2), on which frame several valve leaflets (8) are fastened, as well as a fastening region which connects axially onto the valve frame (2), for fastening in a blood vessel. The fastening region includes a stabilizing ring (14, 14′, 14″, 14″′, 14″″) which defines a given shape and a given diameter and is connected to the valve frame (2) is a force-decoupled manner.
