notes: label: Description
content: This is an example of the first artificial heart valve developed by pioneering heart surgeon Dr. Charles Hufnagel. The interior ball was made of hollow methylmethacrylate. The ball made so much noise the wearer could be heard walking down the hall. Hufnagel later replaced the noisy ball with ones coated with silicone. They proved to be considerably quieter.
