In another application of fluid dynamics, Charles Peskin, of New York University, described a mathematical model for the heart that considers the muscle tissue to be a time-dependent elastic material, which can be modeled using fluid dynamics. The geometry of his model builds on work in the 1950s by Carolyn Thomas, which described the fiber architecture of the heart as a system of spiraling muscle fibers (see Figure 5-2~.

However, some improvements are still needed in the model, including refining the representation of the up-down valve motion, getting a larger valve opening, and decreasing the movement of the base of the heart. It is interesting to note that the Peskin work reflects two of the main themes common to other talks at the workshop.

that would not be apparent from current experimental data. The Peskin heart model is an approximate surrogate for a beating heart, a surrogate that can be manipulated and inspected in ways that a living heart cannot.
