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: FDA Class I designation reflects the agency's determination that there is a reasonable probability of serious adverse health consequences or death. Although the hazard is rare and no adverse events have been reported, the Class I classification requires a minimum severity score of 4 per the rubric.
Plain-English summary
Medtronic is recalling certain implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) that were manufactured with a specific glassed feedthrough. The affected model is the ICD-DR DDMB2D4 EVERA MRI XT IS-1/DF4 INT. Approximately 35,961 units have been distributed in the United States and worldwide.
There is a rare potential for reduced or no energy output during high voltage therapy (typically 0-12 joules) in these devices. This hazard could prevent the device from delivering the electrical therapy necessary to treat life-threatening heart arrhythmias. The FDA classified this recall as Class I, indicating a serious risk to health and safety.
Patients with these implanted devices should confirm their device model and serial number and contact their healthcare provider or Medtronic for specific information about their device and whether additional evaluation is needed.
