Background: Pump thrombosis (PT), the most common cause of failure in ventricular assist devices (VADs), can be mitigated with earlier diagnosis before triggering any clinical events or requiring VAD replacement. Applying machine learning algorithms on pump acoustical signals provides substantial information regarding thrombosis states, and potentially allows for sensitive detection of PT assisting hemolysis biomarkers and pump powers.

Hypothesis: Acoustical signatures of VADs can provide substantial information regarding PT.

Conclusion: Applying machine learning algorithms on pump acoustical signals provides substantial information regarding thrombosis states, and potentially allows for sensitive detection of PT assisting hemolysis biomarkers and pump powers.
