Background:
Bedside manipulation of an Impella CP is often necessary as subtle changes in device position after initial placement can dramatically affect proper function.
Case Presentation:
A 59 year old man in cardiogenic shock on V-A ECMO support underwent Impella CP placement to function as an LV vent. Bedside manipulation led to the Impella dislodging into the ascending aorta and kinking in half. Percutaneous rescue was performed in the cardiac catheterization laboratory by snaring the device, and guiding it back into the LV in a controlled fashion restoring normal function.
Conclusions:
Bedside manipulation of an Impella is often necessary, but may cause device dislodgement. Re-entry into the LV is challenging and replacement of the device carries significant cost and clinical implications. Radial approach, snare guided repositioning offers an alternative solution to an increasingly encountered challenge.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
