Aortic Valve Molds

Description (Brief)
These two molds of a dog's aortic valves were made by Dr. Victor Parsonnet and Dr. Gideon Gestring about 1977. Accompanying the molds is a letter written by Dr. Parsonnet to Mr. Villafana, dated April 22, 2002. Therein he discusses the molds he made "perhaps 25 years ago" when his primary research interest was to develop collagen vessels. He impregnated Dacron mesh with collagen and implanted it into the subcutaneous tissues of dogs. It was successful, which led Parsonnet to attempt to make a leaflet valve of this kind. Their attempts at designing this type of valve failed. "In hindsight it was an interesting adventure, but one that failed." In marker on both valves it reads "DR. GESTRING".
