Invasive arterial blood pressure tracing and LVAD flushing cycle. Timely coincidence of a transient arterial blood pressure reduction, followed by a brief increase, as assessed by invasive radial blood pressure monitoring (a), with the LVAD flushing cycle (scheme, rpm = rotations per minute) (b). Importantly, the flushing cycle transforms into a detectable change in peripheral blood pressure in presence of pulsatile blood flow, indicating left ventricular ejection through the apical inflow cannula and, thus, closure of the aortic valve during the complete cardiac cycle.
