An aortic valve replacement prosthesis (50) which is radially compressible and re-expandable so as to be implantable via a catheter device (200) may comprise a tubular body (55) which has a circumference, which extends along a longitudinal axis (60) and which comprises a first longitudinal end portion (65) which in an implanted state of the prosthesis faces on an ascending aorta side (15) of a native aortic valve (1), a second longitudinal end portion (70) which in the implanted state of the prosthesis faces on a ventricular side (20) of the native valve (1), and an intermediate portion (75) connecting the first and second end portions (65, 70) with each other, wherein the tubular body (55) has an inner circumferential surface (85) and an outer circumferential surface (90), which extend at least substantially concentrically to the longitudinal axis (60), wherein the inner circumferential surface (85) defines an inner lumen (95) of the tubular body (55), and wherein the first and second longitudinal end portions (65, 70) and the intermediate portion (75) of the tubular body (55) are made of a wire-type structure including a plurality of interconnected first wire elements. |
