Spontaneous versus extraction related injuries associated with Accufix J-wire atrial pacemaker lead: tracking changes in patient management.
To make recommendations for management of potentially fatal failure of the Accufix series of atrial J-wire permanent pacemaker leads, we closely monitored the number of injuries and fatalities resulting either from spontaneous fracture of the J-wire or from attempts to extract the lead. In a population of 30,357 patients, 2,298 patients are enrolled in a prospective follow-up Multicenter Study, the remainder are patients with known clinical status from voluntary reporting, and 2,992 patients died following implant. In the remaining 27,365 patients, 6 deaths have been attributed to J-wire related injury (J-inj) while 13 were complications (E-inj) associated with 4,076 lead extraction procedures (3,974 intravascular (intra)/102 primary thoracotomy (PT). The date of occurrences were from 1994 to November 1997.


CONCLUSIONS
(1) Since lead extractions were not conducted in a controlled study, it is not known whether the deaths associated with lead extraction is in excess of what would have occurred if these leads had not been removed in this specific subset. (2) Awareness of the procedure related complication rate appears to have moderated the rate of lead extraction and may ultimately lead to management that reasonably balances the risks of patient injury.
