    The opening and closure intervals of heart valves are important factors regarding an optimal blood flow. Using endoscopic video recordings of heart valves, digital kymography can be a method to visualize and to describe the opening and closure intervals. Based on an adequate segmentation of the kymograms, a quantitative description becomes available for the opening and closure characteristics. Furthermore, by normalizing the measured results, comparisons of mean heart valve oscillations can be achieved. Here, a comparison of artificial with native heart valves obtained under physiological conditions, indicates clear differences in the opening and closure intervals
