What You Need to Know
Boston Scientific has issued a major recall impacting dozens of implantable cardioverter defibrillator (ICD) lead models from the Endotak Reliance, Reliance 4-Site, and Reliance 4-Front families. These leads have been on the market since 2003 for DF-1 models and since about 2009-2010 for DF-4 models.
Because ICD leads are built to last many years, tens of thousands of people may still have these devices implanted worldwide.
Why This Recall is So Serious
The recall is linked to a defect in the ePTFE coating material. This design issue has been shown to cause coil calcification at higher rates than similar products from other manufacturers.
The consequences can be life-threatening:
- 16 deaths reported so far
- 386 serious injuries documented
- Failure of the lead can prevent treatment for ventricular arrhythmia, which is often fatal without immediate intervention
- Removing the leads can be dangerous due to calcification, which increases surgical risk
Who is Affected
Patients who received any of the recalled Boston Scientific ICD leads, including those implanted years ago, may be at risk.
The defect may appear 8 or more years after implantation, meaning problems can arise long after surgery.
If you are unsure whether your device is part of the recall, your implant records or your doctor can confirm the model number.
