Lead extraction is a procedure used to remove one or more leads from inside of the heart.
A lead is a wire that delivers energy from a pacemaker or a transvenous implantable cardioverter defibrillator (ICD) to the heart. Leads that were placed outside the heart during open heart surgery cannot be removed during this procedure.
