Implantable Defibrillators May Fail to Deliver Therapeutic Shock
Medtronic implantable cardioverter defibrillators with a specific feedthrough may produce reduced or no energy output during high-voltage therapy, potentially failing to deliver life-saving shocks.
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. Per the severity rubric, FDA Class I recalls never score below 4. The hazard—potential failure of energy output during critical therapy—presents significant risk of patient harm or death if a life-saving defibrillation attempt fails, though no deaths or injuries are reported in the source.
Plain-English summary
Medtronic Inc. has recalled certain implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds), model DTMA2D4 CLARIA MRI OUS DF4. These devices were manufactured with a specific glassed feedthrough that can cause a rare but serious malfunction: reduced or complete loss of energy output during high-voltage (HV) therapy delivery, typically in the 0-12 joule range.
This defect means the device may fail to deliver the therapeutic electrical shock intended to correct life-threatening heart rhythm abnormalities. Approximately 4,593 units of the affected model have been distributed nationwide and worldwide. The recall affects both currently in-use devices and remaining inventory.
Patients with an affected implantable defibrillator should contact their cardiologist or Medtronic immediately to discuss their device and determine whether replacement, repair, or additional monitoring is needed. Do not discontinue use of the device without medical guidance.
