A method for preparing an edge-rigidized artificial biological valve comprising: first soaking an artificial biological valve in a pretreated glutaraldehyde solution, wherein the artificial biological valve can be partly fixed with glutaraldehyde before, after or during contact with the pretreated glutaraldehyde solution; and then closing the free aldehyde groups, carboxyl groups, amino groups, hydroxyl groups and carbonyl groups formed by the artificial biological valve pretreated with glutaraldehyde with a reducing agent and tannin extract. The edge rigidity of the artificial biological valve is enhanced, so that the long-term stability and durability of the artificial biological valve are improved. |
