Entwicklung einer neuen Dauertestanordnung für Herzklappenprothesen auf der Basis physiologischer Belastungen

The fatigue testing of heart valve prostheses is an important aspect of the entire testing catalogue for the approval of a new heart valve model. In order to get information about wear and fatigue within an acceptable time window it is neccessary to test the valves with rates up to 2000 beats/min. This extremely time shortening makes the comparison between the physiological situation difficult. Currently the testing of wear and fatigue is done according to international guidelines. In this work it could be shown, that the loading of the heart valve prostheses within a fatigue test according to the guidelines is unphysiological. In order to improve this unsatisfactory situation a fatigue tester was developed, which enables the adjustment of physiological loading during fatigue testing.
