Event or Problem Description
It was reported that this cardiac resynchronization therapy pacemaker (crt-p) was in office check and the crt-p was at less than 3 months.Then, the patient left the office and experienced palpitations and diaphragmatic stimulation.The patient came back into the office and it was found that the crt-p was in safety mode.Device replacement was recommended.Subsequently, a revision procedure was performed and the crt-p was explanted and replaced.No additional adverse patient effects were reported.
Additional 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 or determined it had undergone resets and that bradycardia therapy remained available.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 (during telemetry or other higher power device operations) 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.
