Abstract

Many of the factors related to cardiovascular disease seem to be significantly dependent upon the corresponding fluid dynamics of blood flow through the cardiovascular system. A knowledge of such fluid mechanical parameters as shear rate, turbulence intensities and recirculation areas in the entry region of the aorta, for example, would provide a better understanding of associated diseases (e.g., thrombus formation and endothelial damage). In addition, this knowledge would serve as a foundation for the design and testing of prosthetic heart valves.
