  • Cause
    Heartware, now a part of medtronic, has identified the potential for a transient interruption of the electrical connection between an hvad system power source (battery, ac adapter, or dc adapter) and the hvad controller that may result in unintended power switching to the secondary power source and/or unexpected audible tones (“beeping”). this interruption, which occurs while the power source remains physically connected, is due to oxidation of connecting surfaces between a power source connector and the controller’s power source socket, and typically lasts 1-2 seconds. unexpected beeping occurs when the interruption automatically resolves and may cause confusion to the patient or caregiver, as the controller may display sufficient battery capacity or ac/dc connectivity at the time of the audible tone. a critical battery alarm may also be momentarily displayed due to this phenomenon.
  • Action
    Medtronic is developing mitigations for current patients and future system enhancements have been identified and pending approval. Medtronic will inform users when these have been made available. In the interim, Medtronic is providing the following recommendations for power source management of HVAD Systems: - Reinforce the importance of always ensuring TWO power sources (AC or DC adapter plus a battery, OR two batteries) are connected at all times (except when changing a power source) - Reinforce best practice guidance for managing power sources when going to sleep and awakening - Instruct patients to report any persistent, unexpected audible tones to the VAD team for additional instructions Update June 2018: Medtronic HeartWare Field Representatives will coordinate with surgeons to arrange for service of patient's HVAD power source components. This will include application of a lubricant to all HVAD power sources. It is expected that this will be a one-time field service.

    “If our surveillance systems identify a potential performance issue, our personnel promptly evaluate the problem, including, when appropriate, conducting root cause investigations and internal testing to assess whether the product continues to meet specifications and defined performance criteria,” Medtronic told ICIJ in a statement. “In some cases, based on this evaluation, Medtronic may determine that a recall is necessary.” The company said that it communicates with healthcare providers and/or patients and provide recommendations to address such issues. Medtronic noted that these communications can include letters, emails, calls, press releases, physician notifications and social media postings, as well as informing the FDA and other regulators of the actions.
