The present invention concerns an intraluminal vascular prosthesis for implantation into the heart and/or cardiac vessels of a patient, in particular for anchoring in the region of the cardiac valve leaflets. The vascular prosthesis comprises a stent support and a prosthesis material at least partially covering the stent support, such, that a covered proximal portion and a non-covered distal portion are formed. Furthermore, the vascular prosthesis has at least one elongate wire-shaped anchoring structure at the proximal end, which is substantially loop-shaped and which is fixed at two ends to the stent support and which is positioned with its proximal end in the form of a loop pointing in the proximal direction and projecting beyond the proximal end of the stent support.
