Introduction:
In this article we present the extraction of a Micra from a human cadaver implanted 3 years previously with both visual and X-ray imaging taken during the removal.
Methods:
A Micra pacemaker was extracted from a human cadaver with endoscopy and fluoroscopy using a Micra delivery tool. Histological analysis was performed on slices from the tissue surrounding the Micra.
Results:
The fully encapsulated Micra was easily retrieved with a maximum force of 1.9 pounds.
Conclusions:
Even though the Micra was implanted almost 3 years previously, the snaring and extraction of the Micra was performed relatively easily and with minimal force required.
