Time courses of the left ventricular (LV) pressure, the volume, and the aortic pressure for moderate and congestive heart failure states simulated with the HAMC at the pump speeds of aortic valve closure (red) and total work attainment of a normal LV stroke work level (green): (a) and (b) during Sputnik 1 LVAD support; (c) and (d) during Sputnik 2 LVAD support. Blue lines represent time courses of condition characteristics simulated without support. Dot lines demonstrate the left ventricle pressure, single lines demonstrate the aortic pressure, and dash lines represent the left ventricle volume.
