• When assessing potential risk for a patient if their device incorrectly transitions to safety mode, consider patient-specific factors (which may vary over time), including underlying health issues, pacemaker dependence, or problems with pacing.
  • If a device incorrectly enters safety mode, schedule replacement. Boston Scientific does not recommend preventive replacement for affected devices. However, for individual patients, factors such as those listed above in the previous bullet and shared decision-making may support consideration of early device replacement to prevent unintended outcomes. In these cases, the following guidance should be considered:
    • For EL pacemakers, if early replacement is planned, schedule replacement when the service life of the device is four years (or less, if the device currently indicates fewer than four years remaining).
    • For CRT-Ps, if early replacement is planned, schedule replacement when the service life of the device remaining is three years (or less, if the device currently indicates fewer than three years remaining).
  • Perform a system follow-up remotely or in person at least every 12 months. For patients who may not require early device replacement, continue with existing follow-up procedures until there is one year of service life expected and then follow-up every three months until replacement (as indicated in the device's instructions for use).
  • For each patient with an affected device, add the Boston Scientific INGENIO EL Pacemakers and CRT-Ps Physician Letter sent on June 3, 2021 to their medical record to maintain awareness of this topic for the remaining service life of the device.
