title: [Beta-propiolactone for cold sterilization of heart valve transplants].
abstract: Biologic cardiac valve substitutes were sterilized at room temperature using beta-propiolactone with a 0.5 vol.% solution within 120 minutes, with a 1.0 vol.% solution within 90 minutes, and with a 1.5 resp. 2.0 vol.% solution within 60 minutes. The physico-chemic properties of the graft can be influenced by appropriately chosen concentration and sterilizing period. Enlarged procedures for decontamination are not necessary because of the rapid dissolution of aqueous beta-propiolactone solutions.
