Abstract:
A control circuit for a sensorless implantable blood pump configured to determine mitral valve regurgitation includes processing circuitry configured to generate an estimated blood flow waveform from the sensorless implanted blood pump and generate an alert if between an end period of diastole and a beginning period of systole a measured amplitude of the estimated blood flow waveform does not include an inflection point.
