Mean aortic flow, peak left ventricular pressure, left ventricular end diastolic pressure, left ventricular external work, positive and negative rates of change in left ventricular pressure, mean aortic pressure, systolic aortic pressure, and diastolic aortic pressure during baseline (no miniaturized ventricular assist device support), and with miniaturized ventricular assist device support

These data demonstrate unloading of native left ventricle and improvement in flow with miniaturized ventricular assist device support. AoFm, Mean aortic flow; LVPsys, peak (systolic) left ventricular pressure; LVPed, left ventricular end-diastolic pressure; LVEW, left ventricular external work; +dP/dt, positive rate of change in left ventricular pressure; −dP/dt, negative rate of change in left ventricular pressure; AoPm, mean aortic pressure; AoPsys, systolic aortic pressure; AoPdia, diastolic aortic pressure; MVAD, miniaturized ventricular assist device.
