A Simple Explanation
The procedure performed to remove the leads of the Pacemaker that was implanted in the patient’s body.
What is Lead Extraction?
The lead is a special wire that is used to deliver energy from the pacemaker or Implantable Cardioverter Defibrillator (ICD) to the heart muscle.
Lead Extraction is the procedure to extract one or more of the leads. The leads that were placed outside the heart during a open-heart surgery cannot be removed.
Why do we need Lead Extraction?
The lead of the pacemaker are extracted for the following reasons:
How is it done?
Lead extraction, being a minor surgical procedure is performed in the cardiac catheterization laboratory.
There are two approaches to perform this procedure:
Sub-Clavian Approach (Upper Chest)
Here, the leads are extracted through an incision in the upper chest over the Sub-Clavian vein.
Femoral Approach (Groin)
This is performed when the Sub-Clavian approach is not possible. For this, a small puncture is made over the Femoral Vein, in the groin.
The Actual Procedure
Once the incision or puncture is done, depending on the approach, the doctor will numb the site. A special sheath (tube) is inserted in the vein and guided to where the lead connects to the heart. This sheath helps in holding the heart muscle in place while the leads are removed.
A Laser or a special sheath is usually used to help remove the scar tissue, by delivering energy to the tip of the sheath to vaporize the scar tissue. This will, in turn, help in cutting the lead from its attachments and allowing the smooth removal of the leads.
The new leads will either be replaced then or at a later date depending on the reason for the lead extraction.
Once the leads are removed, the doctor will remove the sheaths.
The patient is not allowed to eat or drink 8 hours before the procedure. The patient will have to consult the doctor whether to continue taking the medications.
