Control Strategy for Biventricular Assistance with Mixed‐Flow Pumps

Abstract: A left ventricular assist device (LVAD) is an effective method to rescue severe heart failure. Although some require a biventricular assist, the control method for the biventricular assist device (BVAD) with a rotary pump is rarely shown. The objective of this study was to investigate the strategy for controlling BVAD with rotary pumps by in vivo studies. Using 5 piglets, we set a BVAD through a left thoracotomy and made global ischemia for 30 min by clamping the base of the ascending aorta. After unclamping, … Show more

“…Research has recently focused on control systems for use when continuous-flow pumps are implanted as LVADs 8-11. Several automatic modes have been developed and tested to support the left side circulation 9-12. Most continuous-flow LVADs currently in clinical trials primarily use a fixed-speed control mode.…”

“…68 However, the few documented clinical studies of rotary biventricular support warn of hemodynamic instability. 13,47,48,58,77 All report the importance of continued controller development to prevent pulmonary edema and incidence of suction events in the cannulated heart chamber. Clearly then, balancing of circuit volumes is crucial for any rotary support device, especially rotary BiVADs.…”

“…Preload-based controllers (17)(18)(19)(20)(21)(22)(23) adapt the pump speed according to a parameter that is mostly influenced by the preload of the LV such as the pulsatility of the flow or the motor current, or the gradient of the pump flow against the pump speed.
