FDA Issues Left Ventricular Assist System (LVAS) Monitor Correction: Abbott Issues Correction for HeartMate LVAS System Monitor due to Screen Issues that May Cause Unintentional Pump Stop

This recall involves correcting devices and does not involve removing them from where they are used or sold

Globally approved maximum diameter expansion aims to provide new options in larger diameter and tapered vessels

July 2, 2024 — The U.S. Food and Drug Administration (FDA) announced that Abbott has issued a correction for its HeartMate LVAS System Monitor due to screen issues that may cause unintentional pump stop. This recall involves correcting devices and does not involve removing them from where they are used or sold. The FDA has identified this recall as the most serious type. This device may cause serious injury or death if you continue to use it without correction.

Affected Product

Product Names: Thoratec HeartMate System Monitor

Unique Device Identifier (UDI-DI): 00813024010142, 00813024010852

Model Numbers: See full list of affected devices below.

Lot/Serial Numbers: All serial numbers

What to Do

The affected devices are only used by clinicians in a clinical setting such as in an operating room or clinic.

For clinicians

All HeartMate System Monitors may potentially display screen issues.

  • Restart the System Monitor unit before connecting to the patient controller if:
    • The unit has been running for a long period of time, or
    • If screen issues are observed
  • To restart, turn off and then turn on using the On/Off Switch located on the back of the System Monitor. Full restart takes approximately 10 seconds.
    • LVAD settings will remain the same if the unit is restarted while connected to the patient’s controller.
  • Check all cables and connections are secure and undamaged if screen display issues continue after System Monitor restart.
  • Use a different System Monitor if screen issues continue.

In case of pump stop:

If the "Stop Pump" button is inadvertently pressed due to these display issues, the pump will stop for a moment and restart unless the pump stop button is pressed longer than ten seconds. In that case, the pump will stop and the controller will alarm "Pump Off Alarm."

  • Press any button on the controller to attempt pump restart and resolve "Pump Off Alarm," as directed in the Instructions for Use.

On May 8, 2024, Abbott Medical sent all affected customers an Urgent Medical Device Correction letter that included the clinician actions listed above as well as the following additional details and actions:

  • Restarting the System Monitor should resolve the display issues in most cases.
  • Distribute the notice to those who need to be aware within the institution and forward to any institution where potentially affected devices have been transferred.
  • Complete and return the acknowledgement form attached to the letter by email to [email protected].

Reason for Correction

Abbott Medical is recalling the HeartMate System Monitor, part of HeartMate LVAS, due to atypical behavior of the System Monitor screen (screen issues). The screen issues include screen freezing, overlapping buttons or screens, unresponsive buttons, distorted text or graphics, and wrong or missing information on the display. These issues can cause a clinician user to inadvertently change pump settings or press the pump stop button.

The use of affected product may cause serious adverse health consequences, including decrease in blood pressure and inadequate flow of blood (hemodynamic compromise) caused by a pump stop. This can lead to stroke, irreversible brain damage, heart or organ failure, and death.

There have been 14 reported injuries. There have been no reports of death.

Device Use

The HeartMate System Monitor is one part of a HeartMate Left Ventricular Assist System (LVAS). The System Monitor is used in the operating room or during clinic visits to:

Monitor system operation closely during LVAD implant

  • Display information about system performance, including current operating mode, pump flow, pump speed, and overall operational status
  • Program system parameters such as pump speed
  • Assess and track alarm conditions
  • View and save performance data
  • Record data at specific intervals to download for review and analysis

An LVAS is used to help the heart pump blood when it is not able to do so effectively on its own. It can be used while waiting for a heart transplant, to help the heart recover, or as a permanent solution when a transplant isn't an option.

Contact Information

Customers in the U.S. with questions about this recall should contact their local firm representative or Abbott Medical Technical Support at 1-800-456-1477.
