Although pacemakers and ICD pulse generators need to be replaced every four to ten years, the leads (wires) that connect the device to the heart usually remain in place forever. Do leads need to be removed? Under rare circumstances, these leads will have to be removed. The most common reason for this is the development of an infection on the leads. This type of infection is nearly impossible to treat with antibiotics so it may be necessary to remove (extract) the leads. Leads that have been in place less than six months usually can be removed without much difficulty or risk. However, leads that have been in place for many years may require a special laser cutting sheath to free them from the wall of the heart. Lead extraction Although similar to having a pacemaker or ICD implanted, lead extraction is more difficult and is associated with a greater chance of complications. In the unlikely event that you require this procedure, you will be provided with more details about the procedure that are unique to your case. |
