Event Description

It was reported that cardiac resynchronization therapy pacemaker (crt-p) triggered a fault code and entered into safety mode.The patient fell and went to the hospital.It was noted that all other implanted device data shown for this patient reflected the status as of the previous implanted device transmission.The patient was noted as dependent by doctor, the crt-p was explanted and has been returned for analysis.A new crt-p device was implanted at the same procedure.No additional adverse patient effects were reported.

Manufacturer Narrative

Upon receipt at our post market quality assurance laboratory, this device was thoroughly inspected and analyzed.Interrogation of the device confirmed it was operating in safety mode due to system resets.It was confirmed that brady therapy remained available.The system resets occurred during a telemetry session and caused the device to enter safety mode.Engineers determined that this device was demonstrating behavior consistent with a high internal cell impedance within the battery.The high internal impedance resulted in the system resets due to temporary high-power consumption related to telemetry attempts and subsequent reversion to safety mode operation.Boston scientific has issued a field safety notice regarding ingenio extended life (el) and cardiac resynchronization therapy pacemaker (crt-p) devices that may exhibit this behavior.This particular device is included in the high impedance in ingenio extended life (el) pacemaker and crt-p advisory population.This investigation will be updated should further pertinent information be provided.
