Figure Legend:
(Top) LV volume during transition from no assist to 20 mmHg of assist. Note that though the end-diastolic volume (EDV) decreased with assist, the reduction in end-systolic volume (ESV) was greater; thus the stroke volume is actually increased. (Bottom) Device pressure during transition from no assist to 20 mmHg of active assist. Note that the device pressure goes from 0 mmHg during systole (before device activation) to 20 mmHg during systole (following device activation). The end-diastolic pressure (EDP) in the device is constant at 15 mmHg before assist begins and falls to 10 mmHg after assist starts.
