Placement screen on the Automated Impella Controller. Placement screens generated by a fluid-filled pressure lumen (Impella 2.5 and CP) are shown. (Left) The transvalvular heart pump is appropriately positioned and shows an aortic waveform in the placement signal and a pulsatile motor current. (Middle) The blood inlet and outlet areas are both in the aorta (aortic waveform placement signal, flat motor current). (Right) Both the inlet and outlet areas are in the ventricle (ventricular waveform placement signal, flat motor current). Please see figure A1 for placement screens generated by a differential pressure sensor. Adapted and reproduced with permission from Abiomed Inc. (USA).
