Abstract

Blood pump systems include a left ventricular assist device that is controlled to inhibit onset or worsening of right ventricular failure. A blood pump system includes a left ventricular assist device, a pulmonary artery pressure sensor, and a controller. The pulmonary artery pressure sensor is configured for generating a pressure signal indicative of a blood pressure in the pulmonary artery of the patient. The controller is configured to control operation of the left ventricular assist device, process the pressure signal to generate pulmonary artery pressure data indicative of right ventricular afterload of the patient, and adjust at least one operating parameter of the left ventricular assist device based on the pulmonary artery pressure data to reduce a deviation between the right ventricular afterload of the patient and a target right ventricular afterload for the patient.
