Biological Heart Valves. Biological Heart Valves are made of tissues and valves derived from animals or human donors. Their biggest advantage is that they do not cause blood clotting on their surface and truly replicate the form and function of the normal human valve.

Cook 30 minutes per pound, until internal temperature reaches 160 F. Country ham shanks are smoked, brine-cured and very salty. Soak overnight, drain; boil in unsalted water 25 minutes per pound.
