    Abstract: The analysis and procedure for obtaining the average fatigue damage rate, and hence a measure of longevity, of a prosthetic heart valve is presented. Design charts are developed to obtain measures of longevity of prosthetic heart valves, for various values of valve geometry characterizing parameter, valve’s in vivo pressure loading characteristics and the fatigue properties of the valve material. Such design charts can be updated when more reliable information about the fatigue properties of valve material (in a physiological fluid environment) becomes available.
