Claim 9:
10. A method of implanting a cardiac valve prosthesis to an individual in need thereof, the method comprising the following steps:
a) excising or harvesting body tissue from a donor,
b) shaping the body tissue in a shaping process to give the body tissue a shape and size of a cardiac valve of a recipient,
c) fixation and stabilization of the body tissue by a cross-linking agent, thereby preserving the shape given to the body tissue by the shaping process and thus obtaining a cardiac valve prosthesis, and
d) implanting the cardiac valve prosthesis to the recipient,
wherein a mold for an individually personalized cardiac valve prosthesis is used in the shaping process to give the body tissue the desired shape,, wherein the mold for an individually personalized cardiac valve prosthesis is manufactured by a method comprising the following steps:
b1) providing or obtaining 3-D imaging data of an impaired cardiac valve of an individual by an appropriate imaging method,
b2) 3-D reconstructing the 3-D imaging data, thereby at least partially correcting impairments of the impaired cardiac valve so as to obtain reconstructed 3-D imaging data representing a virtual cardiac valve having a performance that better corresponds to the performance of a non-impaired cardiac valve than the performance of the impaired cardiac valve does,
b3) using the reconstructed 3-D imaging data to generate a virtual 3-D mold for an individually personalized cardiac valve prosthesis, and
b4) using the virtual 3-D mold to manufacture a real mold for an individually personalized cardiac valve prosthesis, and, wherein a diameter of the obtained cardiac valve prosthesis has an oversizing of 10 to 50 % with respect to a diameter of a blood vessel to be treated by the cardiac valve prosthesis when implanted.
