The objective of this paper is to solve the equation of motion of semilunar heart valve vibrations. The vibration of the closed semilunar valves are modeled by a Caputo fractional derivative of order α.Using a Laplace transformation, a closed-form solution is obtained for the equation of motion in terms of a Mittag-Leffler function.An alternative method for a semi-differential equation α = 1/2 when is also examined. The simplicity of theMathematica solution makes it ideal for testing the accuracy of numerical methods.This solution can be of some interest for fitting experimental data.
