Implantable defibrillators may fail to deliver high-voltage therapy during treatment

Certain Medtronic ICD and CRT-D devices with a specific feedthrough may fail to deliver energy during high-voltage therapy. This rare defect affects 9,325 units worldwide and could compromise cardiac protection.

What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: This is an FDA Class I recall involving life-critical implanted defibrillator devices. While no illnesses or deaths are reported in the source, the potential failure mode—reduced or absent high-voltage therapy output—represents a serious risk to patients dependent on these devices for cardiac protection. FDA Class I classification mandates a minimum severity score of 4.

Plain-English summary

Medtronic has recalled approximately 9,325 units of its ICD COBALT XT VR MRI DF4 implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) manufactured with a specific glassed feedthrough component. Affected devices may produce reduced or no electrical energy output during high-voltage (HV) therapy delivery, which typically operates at 0-12 joules.

The defect poses a serious risk because it could prevent the device from delivering the high-voltage therapy needed to treat dangerous abnormal heart rhythms. While the potential for energy loss is rare, the failure mode—inability to deliver therapy—could compromise the device's critical function of protecting the patient from life-threatening cardiac events.

These devices have been distributed throughout the United States and worldwide. The affected units are identified by specific lot serial numbers that have been provided to healthcare facilities and cardiologists.

Patients with an affected ICD or CRT-D should contact their cardiologist or the implanting facility to determine whether their device is among those recalled. Verification can be done using the device's serial number. Patients should continue with regular scheduled device follow-up visits and seek immediate emergency medical care if they experience symptoms of heart rhythm problems.
