A new high priority recall has been issued for Medtronic HVAD Pump Implant Kits. These kits are used in patients with severe heart disease, especially those who need a transplant but have not yet found a donor. When this problem occurs, the pumps do not respond as intended to restart the heart. Delays and failed reactivations can lead to further heart damage or even death. To date, 19 serious incidents and 2 deaths have been attributed to the equipment.

The FDA recall notice and instructions for healthcare professionals and affected patients are listed below.

The FDA has identified this as a Class I recall, the most serious type of recall. Use of these devices could result in death or serious injury.

Device usage

The HeartWare Ventricular Assist Device (HVAD) Pump Implant Kit is part of the HeartWare HVAD system that allows the heart to continue pumping blood to the rest of the body. The HVAD System is used as a bridge to heart transplants in patients at risk of death from end-stage left ventricular heart failure, to restore heart tissue, or as target therapy (DT) in patients who are not scheduled to have new transplants.

Reason for the recall

Medtronic is recalling the HVAD Pump Implant Kit because the device may fail to start, restart, or delay restart after the pump stops. These delays or errors in starting or restarting have occurred during pre-implant testing, during the implant, or in a variety of post-implant situations. If the device delays, or fails to start or restart, it could cause serious patient harm, including heart attack, worsening heart failure, need for additional procedures and hospitalizations, or death.

There were 29 complaints related to this device issue, including 19 serious injuries and 8 cases from patients who had a life-threatening event but recovered with no long-term effects. Two deaths have been reported.

Who can be affected

  • Healthcare providers using the affected HVAD pump implant kits
  • Patients who have had surgery with the affected device

What should I do

On December 18, 2020, Medtronic sent an urgent medical device communication letter to all affected customers, and on December 23, 2020, Medtronic sent an urgent medical device communication letter to all accounts that had previously purchased a Medtronic HVAD pump. In the notification, customers were instructed:

  • Inform healthcare providers and employees about the following points from the current Instructions for Use (IFU) to avoid unnecessary pump stops:
    • Do not disconnect the drive train from the controller.
    • Do not disconnect both power sources (batteries and AC or DC adapter) from the controller at the same time. An external power source should always remain connected to the controller.
    • Do not replace the controller unless specifically directed by a high priority alarm condition or by a VAD team member.
    • Reinforce the correct response to a [Controller Fault] Alarm and [Electrical Fault] Alarm. These are medium priority alarms that are not related to an immediate pump stop. These alarms lead to the word [Call] On the controller display, notify the patient to call their doctor.
    • Make sure that the power sources and the data cable in the controller ports are well connected.
  • Prior to a controller exchange, instruct patients implanted with one of these identified pumps to contact their ventricular assist device coordinator and coordinate a controller exchange in a clinical setting.
  • Determine whether a controller replacement is deemed necessary for patients implanted with any of these identified pumps, and consider the following:
    • The controller replacement should be performed under the supervision of the clinician in a controlled environment in which the patient can receive immediate hemodynamic support. A failed restart can be serious.
    • A high priority when the pump stops [VAD Stopped] Alarm will result in the words [Change Controller] or [Connect Driveline] in the controller display. Once the power and driveline connections are restored, if the pump does not restart:
    • Consider switching the current controller off and on again or replacing the controller. This allows the restart algorithm to be reset and restarted. The controller automatically tries to restart the pump a maximum of 30 times. the [VAD Stopped] The alarm will start after five (5) attempts.
    • If the pump still does not restart, continue with temporary hemodynamic support and pump replacement.
  • Schedule a controller replacement before the internal controller battery reaches the end of its life and trips a [Controller Fault] Alert when a patient’s controller is longer than two (2) years of service.
    • Although a [Controller Fault] Alarm is a medium priority alarm unrelated to a pump stop. Proactively planning a controller replacement can help prevent a patient from responding to the alarm by replacing a controller outside of a clinical setting. According to the IFU, patients should call their doctor if they receive a medium priority alarm.
  • Check the serial numbers in the letter and confirm that the patients are still receiving assistance.
  • Share the letter with anyone who needs to know within organizations or to organizations where potentially affected patients have been transferred.
  • Complete a Physician Confirmation Form (attached to the letter) and email it to RS.CFQFCA@medtronic.com.
