Pacemakers and implantable cardiac defibrillators (ICDs) are used to provide electrical impulses to the heart. This is done through two or three thin wires, or leads, in the veins that connect the heart to the device.
There are approximately three million Americans with pacemakers or ICDs in the United States, according to the American Heart Association. At some point, about 1 to 2 percent will have leads that stop working and require removal. Lead extraction may be necessary for a handful of reasons:
Infection - This is the most common reason for extraction. When this occurs, the leads and implanted device must be completely removed.
Damage - If the leads are damaged, they have to be removed and replaced.
Exit block - When damaged leads are not removed or scar tissue is created at the end of the lead, blockage can occur and the wires have to be removed.
What to Expect
The procedure is minimally invasive and usually requires an overnight stay in the hospital to ensure the device is working properly and that your heart rhythm remains normal. The procedure goes as follows:
- It is performed through an incision in either the chest or groin. Usually this is done over the previous incision or through a mini-thorectomy (a small incision in the chest between two ribs).
- A tube goes in the vein and a laser or extraction device removes scar tissue from the lead.
- The leads are removed and your doctor may implant new ones at this time.
