MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION VALITUDE X4 CRT-P; PULSE GENERATOR, PACEMAKER, IMPLANTABLE, WITH CARDIAC RESYNCHRONIZATION (CRT-P)

Model Number U128

Device Problems Premature Discharge of Battery (1057); Incorrect, Inadequate or Imprecise Result or Readings (1535); Battery Problem (2885)

Patient Problem No Clinical Signs, Symptoms or Conditions (4582)

Event Date 09/20/2021

Event Type  Injury  

Manufacturer Narrative

If additional information is received, a supplemental report will be filed at that time.

Event Description

It was reported that this cardiac resynchronization therapy pacemaker (crt-p) was explanted due to safety mode and premature battery depletion.A new device was implanted and remains in service.No additional adverse patient effects were reported.

Manufacturer Narrative

If additional information is received, a supplemental report will be filed at that time.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.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.
