The effects of the continuous-flow output on renal and intestinal microcirculation have not
been extensively studied. To address this, the Heartware HVAD pump loaded with …

Extra hemodynamic energy is one of the major benefits of pulsatile flow, improving blood
flow to vital organs. But most (80%) of the hemodynamic energy generated from pulsatile …

A rotary blood pump inherently provides only one noninvasive “observable '” parameter
(motor current) and allows for only one “controllable” parameter (pump speed). To maintain …

Continuous-flow pumps are small, simple, and respond physiologically to input variations,
making them potentially ideal for total heart replacement. However, the physiological effects …

Background Rotary blood pumps operate at a constant speed (rpm) that diminishes vascular
pulsatility and variation in ventricular end-systolic and end-diastolic volumes, which may …

To evaluate the clinical meaning and effects of afterload‐dependent flow fluctuation in a
centrifugal pump, concomitant measurement of flow rate and mixed venous oxygen …

Many types of rotary blood pumps and pump control methods have recently been developed
with the goal of clinical use. From experiments, we know that pump flow spontaneously …

Abstract Changes in systemic vascular resistance (SVR) in response to diminished pulse
perfusion were analyzed over a dynamic range of flow conditions. An axial flow LVAD …

This model study evaluates the effect of pump characteristics and cardiovascular data on
hemodynamics in atrio–aortic VAD assistance. The model includes a computational …

A new dual-inlet mixed-flow blood pump was designed and tested in our laboratory. The
objective of the present study was to analyze hemodynamic characteristics of the pump …
