Methods and apparatus for accelerated wear testing of prosthetic heart valves apply non-sinusoidal pressure waveforms. The waveforms may maintain a threshold reverse pressure for a desired duration while limiting a peak reverse pressure. Apparatus may include a fluid impeller such as a bellows or a piston driven by an actuator having a position controlled by a motion control system. The apparatus may include a pressure control system comprising one or more bypass channels and bypass valves controlling a resistance of the bypass channels to fluid flow. The bypass valves may be controlled in real time.
