The reported events of no pacing, no magnet response, no inductive telemetry, and no radiofrequency telemetry were confirmed.The device was received with no telemetry communication and no output.A visual inspection of the header attachment area detected an anomaly between the pre-cast header and titanium case.The device was cut open to enable further testing and the battery was found depleted.The feedthrough leak test was performed, indicating a device hermeticity breach.This is consistent with feedthrough damage as a result of fluid intrusion between the header and case, and subsequent fluid ingress to internal electronics.The hybrid circuitry was tested, and results indicated elevated current drain, consistent with moisture damage, resulting in the reported events.A manufacturing process anomaly may have occurred, which resulted in the header bonding anomaly.
