The US Food and Drug Administration has issued an early alert for a critical software error affecting the Automated Impella Controller used with left ventricular Impella heart pump devices manufactured by Abiomed. The controller may unexpectedly restart during operation, potentially disrupting life-sustaining cardiac support for critically ill patients.
Critical Software Malfunction Identified
The FDA early alert describes a software error that causes the Automated Impella Controller to restart when used with left ventricular Impella devices. This unexpected restart can interrupt the continuous mechanical circulatory support that critically ill patients depend on for survival.
Impella devices are temporary mechanical circulatory support systems designed to help the heart pump blood in patients with severe heart conditions. The controller manages the device’s operation, making any malfunction potentially life-threatening.
Immediate Safety Concerns for Patients
According to the FDA alert, healthcare providers using Automated Impella Controllers should be aware that the restart issue can occur without warning. During a controller restart, patients may experience temporary loss of mechanical circulatory support, which could lead to hemodynamic instability in already critically ill individuals.
The FDA recommends that clinicians closely monitor patients with Impella devices and be prepared to take immediate corrective action if a controller restart occurs. Alternative support measures should be readily available as per established patient safety protocols.
Healthcare Provider Response Required
Medical facilities using these devices should review their emergency procedures and ensure staff are trained to respond quickly to controller malfunctions. The FDA’s Medical Device Reporting system encourages healthcare providers to report any incidents related to this controller issue.
According to the FDA alert, Abiomed is working with the FDA to address the software problem and develop a solution. Healthcare providers should contact the manufacturer for specific guidance on managing affected devices and stay updated on device safety communications.
The Automated Impella Controller software error causes unexpected restarts that can interrupt life-sustaining cardiac support in critically ill patients using left ventricular Impella devices.

Frequently asked questions
What is an Impella device and why is this controller important?
Impella devices are temporary mechanical heart pumps that help circulate blood in patients with severe heart failure or during high-risk cardiac procedures. The Automated Impella Controller manages the device’s operation, making it essential for patient safety.
How serious is a controller restart during treatment?
According to the FDA alert, a controller restart can temporarily interrupt mechanical circulatory support, which may cause dangerous drops in blood pressure and organ perfusion in critically ill patients who depend on the device for survival.
What should hospitals do if they use these controllers?
The FDA recommends that hospitals ensure staff are trained to respond quickly to controller malfunctions, have backup support measures ready, and closely monitor all patients with Impella devices until the software issue is resolved.
The FDA continues to work with Abiomed to investigate the full scope of this software issue and develop appropriate corrective measures. Healthcare providers are encouraged to report any controller restart incidents to help authorities better understand the problem’s frequency and impact on patient outcomes.
