lead extraction
Surgical or percutaneous removal of chronically implanted pacemaker or defibrillator leads from the cardiovascular system.
Full Definition
Lead extraction is the complete removal of chronically implanted pacemaker or defibrillator leads from the cardiovascular system, typically performed when leads have been in place for more than one year. The procedure may be necessary due to lead malfunction, infection, lead-related complications, or device upgrades. Extraction techniques range from simple traction to complex procedures using specialized tools like laser sheaths or mechanical cutting devices, and the procedure carries significant risks including vascular injury and cardiac perforation.
Usage
Usage note: High-risk procedure requiring specialized expertise and surgical backup. Often abbreviated as TLE (transvenous lead extraction).
