It was reported that the patient presented during clinical follow-up.In clinic, the pacemaker presented with loss of capture, failure to interrogate, and no magnet response.Previous interrogation noted that the device exhibited premature battery depletion and it was noted that the patient felt fatigue since (b)(6) of 2023.The reported device was explanted.The patient's condition was unknown.

The reported events of failure to capture, inability to interrogate, no magnet response and premature depletion were confirmed.As received, the device telemetry and output were not available.A device history record (dhr) review was performed and all required manufacturing processes and inspection steps were confirmed to be completed per the requirements.The device met specifications prior to leaving abbott manufacturing facilities.Visual inspection of the header attachment area detected a bonding anomaly.A device hermeticity breach was observed, consistent with feedthrough damage as a result of fluid intrusion between the header and case, and subsequent fluid ingress to the internal electronics.The device was cut open to enable further testing and battery was found depleted.Hybrid circuitry was tested, indicating elevated current drain, consistent with moisture damage, depleting the battery prematurely, and resulting in the reported events.A manufacturing anomaly may have occurred, which resulted in the header bonding anomaly.
