A great number of investigators, inventors, and biomedical engineers are
heavily involved in the design, development, and testing of new and
improved artifi cial cardiac valve substitutes. The ultimate objective is to
develop a substitute that closely mimics the function and durability of
normal valves. Although there have been impressive advances in the fi eld
