Abstract
A method for preparing a pre-loadable biological heart valve capable of rapid rehydration includes performing a cross-linking treatment, wherein a biological valve is cross-linked by soaking in an aqueous glutaraldehyde solution; performing a hydrophilic treatment, wherein the biological valve is soaked in a solution containing a hydrophilic molecule and a condensing agent, to allow the hydrophilic molecule to be immobilized on the biological valve by chemical grafting; and performing a drying treatment, wherein the biological valve after the hydrophilic treatment and the cross-linking treatment is dried to obtain the pre-loadable biological heart valve capable of rapid rehydration.
