Percentage change calculated in comparison to baseline conditions for left ventricular external work (top left panel), right ventricular external work (top right panel) and left and right atrial pressure–volume loop area ((bottom left panel) and (bottom right panel)). The above values were obtained when the Impella rotational speed was set to 35,000, 45,000 and 50,000 rpm. During the simulations with IABP support the driving and vacuum pressures were set to Pd = 260 mmHg and to Pv = −10, Pv = 0 and Pv = +10 mmHg, respectively.
