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.

Methods and systems for controlling a left ventricular assist device

The present invention is generally related to methods and systems for preventing onset or worsening of RHF in patients with implanted ventricular assist devices. More particularly, the present invention relates to identifying patients at risk for RHF following implantation of a ventricular assist device based on pulmonary artery pressure measurement and/or trends and adjusting a pump operating parameter to prevent or reduce the onset or worsening of RHF in such patients, improve patient outcomes, or reduce mortality risks associated with VAD implantation. In particular, a pump operating parameter may be adjusted to reduce or minimize particularly high pressure loads on a patient's heart or amount of time the patient is exposed to such high pressure loads following implantation.

Methods for controlling a left ventricular assist device

Controllers and methods for heart treatments are disclosed herein. The controller can include a communication module that can send and receive data from heart therapy devices. The controller can include memory including stored instruction. The controller can include a processor. The processor can receive a signal of an impending electrical treatment at a processor. The processor can determine a current operating parameter of a blood pump communicatingly coupled with the processor. The processor can determine an adjustment to the operating parameter of the blood pump to affect an impedance of heart tissue to be affected by the impending electrical treatment. The processor can control the blood pump according to the adjustment to the operating parameter of the blood pump.
