摘要

Abstract The AB5000 Circulatory Support System is paracorporeal pulsatile ventricular assist device. The AB Portable Driver is a portable console for this system. We experienced two cases with accelerated hemolysis while receiving support by the AB Portable Driver. The purpose of this study was to clarify the mechanical differences associated with the hemolysis between the AB5000 console and the AB Portable Driver. The mock circulatory system modeled by an AB5000 ventricle and a blood sampling bag of vinyl chloride was run with an AB5000 console or AB Portable Driver. The peak drive‐line pressure, the mean arterial cannula pressure and the pumping rate of the VAD were recorded. The AB5000 console generated a peak drive‐line pressure of 280–300 mm Hg in LVAD mode and 210–220 mm Hg in RVAD mode, approximately 100 mm Hg lower than officially documented. In contrast, the AB Portable Driver generated pressures of 310–330 mm Hg in LVAD mode and 230–250 mm Hg in RVAD mode, 65–95 mm Hg higher than officially documented. The AB Portable Driver console generates higher drive‐line pressures than the AB5000 console, possibly explaining the accelerated hemolysis.
