title: Elasticity of frozen aortic valve homografts.
abstract: Homograft aortic valves were treated and stored in different ways and then tested for elastic qualities. It appears from the findings that the most satisfactory long-term storage technique is to flash-freeze the valves in the presence of dimethyl sulphoxide immediately after dissection.
