This screenshot you provided shows the monitor of an Impella CP which appears to be positioned in the aorta instead of the correct position within the left ventricle (LV).

  • Ao Pressure: 126/73 mmHg (Mean 93 mmHg), indicating the device is picking up aortic pressure signals.

  • LV Pressure: There is a loss of clear pressure signals from the left ventricle, which would normally be used to monitor proper positioning.

  • The low fluctuation of the motor current, (with readings showing a current of 399/350 mA), suggests that there is minimal pressure gradient across the two pressure sensors of the Impella device. These sensors normally detect pressure differences between the aorta and the left ventricle.


The motor current stability (almost flat) suggests that the Impella is likely not in the left ventricle (as intended) but rather in the aorta. Since both sensors are exposed to aortic pressure, there is little to no pressure gradient detected between the aorta and the left ventricle.


The device was introduced about 4 cm and here is a screenshot of an appropriate position. This was confirmed with echocardiography:

This is totally new procedure for me.

Jazak Allah khair.
