Placement screen. Placement screens generated by a differential pressure sensor (Impella LD and 5.0) in an appropriately placed transvalvular heart pump (left) and inappropriately placed transvalvular heart pump (right) are shown. (Right) The inlet and outlet areas of the pump are in the same chamber (either the aorta or ventricle), resulting in no pulsatility in the placement signal or motor current.
