Quick Answer: What is lead extraction?
Lead extraction is the removal of one or more leads, the insulated wires connecting a pacemaker or ICD to the heart, often because of infection, breakage or malfunction. Under general anesthesia, an imaging-guided sheath frees the lead from scar tissue. The stay is typically overnight. Call your provider for breathing difficulty, fever above 101°F or unusual bleeding. [1]
What the research says
Lead extraction succeeds in most patients when done in experienced centers. A European registry of 3,555 consecutive patients (3,510 underwent extraction) at 73 centers in 19 countries reported complete clinical success in 96.7% (95% CI 96.1–97.3%) and radiological success in 95.7%. Major complications and deaths were significantly lower in high-volume centers (Bongiorni et al., Eur Heart J, 2017). [2]
Laser use has been linked to different outcomes than non-laser methods. In a meta-analysis of 68 studies, non-laser extraction had lower major complications (0.7% vs 1.7%), less superior vena cava injury (0% vs 0.5%) and higher complete success (96.5% vs 93.8%) than laser extraction in pooled rates. These were pooled results from mostly observational studies, so the choice of tool is made case by case (Akhtar et al., Europace, 2023). [3]
What is a cardiac lead?
A lead is a special wire surrounded by insulation that delivers energy from a pacemaker or implantable cardioverter-defibrillator to your heart. These devices are for people who have, or are at risk for, abnormal heart rhythms (arrhythmias), and they help maintain a steady rhythm. [1]
Depending on the device, there may be up to three leads. They run along the inside of a vein from the device to the right side of the heart. When the device detects an arrhythmia, it releases a burst of energy that travels along the leads to the heart and resets it to a normal rhythm.
What is lead extraction?
Lead extraction removes one or more leads from inside the heart. It cannot remove leads that were placed on the outside of the heart during open-heart surgery.
After the device is first implanted, scar tissue forms and secures the lead in place. Over time this tissue builds up, and the lead may need more energy to work than the device can deliver. This is called an exit block. Scar tissue also makes leads challenging to remove, so special instruments and the skills of an experienced cardiac provider are needed to free the lead without damaging the blood vessel. [1]
Why would someone need a lead extraction?
The most common reason is a device infection, which usually spreads to the lead from an infection in the blood (bacteremia). The heart valves may also become infected (infective endocarditis). In both cases, your provider will remove the device and leads. [1]
Reason for extraction | What it means |
Device infection | Infection usually reaches the lead from an infection in the blood. |
Infective endocarditis | Infected heart valves; the device and leads are removed. |
Lead-triggered arrhythmia | The lead itself sets off an abnormal rhythm. |
Blood clots or scar tissue | They disrupt blood flow through the vein. |
Broken lead | The inside or outside of the lead breaks. |
Malfunction or recall | The lead does not work properly, or the manufacturer recalls it. |
Exit block | Too much scar tissue at the lead tip affects device performance. |
A reason on this list does not mean a particular person needs extraction. A cardiac specialist evaluates the device, leads, symptoms, likely cause and safest approach.
How is lead extraction performed?
The subclavian approach is the most common. Your provider extracts the leads through an incision at the subclavian vein, under the collarbone (clavicle). The other approach is through an incision in the groin next to the femoral artery, used when the subclavian approach is not possible. [1]
Approach | Where the incision is | When it is used |
Subclavian | Under the collarbone, at the subclavian vein | The most common approach |
Femoral | In the groin, next to the femoral artery | When the subclavian approach is not possible |
What happens during the procedure?
During lead extraction, the provider uses general anesthesia and guides a special sheath along the lead to break up scar tissue before removing the lead.
You receive general anesthesia, which puts you to sleep and temporarily blocks sensation. [1]
Your provider places a special sheath (tube) in a vein and advances it to the lead, covering the lead with the sheath. [1]
Real-time imaging (fluoroscopy) guides the sheath.
Instruments at the sheath tip break up scar tissue, freeing a small section of the lead. [1]
The provider advances the sheath to the next portion of the lead that is still secured and repeats the process. [1]
When the lead is free of scar tissue, the provider removes it along with the sheath. [1]
The incision is closed and covered with a bandage. [1]
What happens during laser lead extraction?
Your provider can also use a laser device attached to the tip of the sheath. Laser energy creates heat that vaporizes scar tissue. Laser is one possible part of an extraction; your cardiac team chooses the instruments and approach that suit your situation. [1]
Will new leads be implanted?
Sometimes your provider implants new leads during the extraction procedure, and sometimes later. It depends on the reason for removal. If there is an infection, it is essential to get rid of it before implanting new leads. [1]
What are the possible benefits?
The benefits of lead extraction depend on why it is needed and may include a fully working pacemaker or ICD, relief from arrhythmias or restored blood flow. Extracting leads may result in:
A fully functioning pacemaker or ICD, if the lead had been malfunctioning or fractured. [1]
Improved device efficiency, if there was an exit block. [1]
Relief from arrhythmias, if they were due to interactions with the lead. [1]
Restored blood flow, if blood clots or scar tissue from the lead were causing a blockage. [1]
What are the risks?
Lead extraction carries risks like any invasive procedure, including anesthesia complications, a broken lead, major bleeding and damage to the heart or blood vessels. [1]
Anesthesia complications
Breaking the lead
A major bleed requiring a blood transfusion
Perforating the heart with the lead tip
Tearing a blood vessel
Blood leaking around the heart
This list is not a personal risk estimate. Your cardiac team can explain the risks that apply to your device, how long the leads have been in place, scar tissue, your health history and the planned approach.
What is recovery like?
Recovery after lead extraction typically includes an overnight hospital stay, though sometimes longer. Depending on your situation, you may need to:
Recovery detail | What to expect |
Typical hospital stay | Overnight, but sometimes longer. |
Femoral approach | If leads were removed through the femoral artery, you need to lie flat for several hours afterward. |
Delayed replacement | If the device and leads are not replaced during the extraction, you may stay in the hospital until the next implantation can be performed. |
Infection-related extraction | You will likely receive antibiotics after the procedure. |
Next-morning check | A chest X-ray the morning after extraction checks the position of any newly implanted leads. |
When should I contact my healthcare provider?
After a lead extraction, contact your healthcare provider if you have difficulty breathing, a fever greater than 101°F, swelling or unusual bleeding or drainage. For severe shortness of breath, chest pain or fainting, call 911 or your local emergency number. [1]
Difficulty breathing
A fever greater than 101°F
Swelling at the incision site or in your fingers or toes
Unusual bleeding or drainage
Do not try to work out the cause of these symptoms on your own. Your care team can tell you whether a symptom is expected, needs prompt review or needs emergency care.
What questions should you ask before lead extraction?
Questions to ask before lead extraction cover why the lead needs removal, the approach and anesthesia, the most relevant risks and the hospital stay and follow-up care.
Why is this lead being considered for removal?
Is infection involved, and how will it be treated?
Will the subclavian or femoral approach be used, and why?
What type of anesthesia will be used?
Will fluoroscopy or a laser device be used?
Will new leads be placed during the same procedure or later?
Which risks are most relevant to my leads and health history?
How long might I need to stay in the hospital, and will I need antibiotics?
Will a chest X-ray check the position of new leads?
Which symptoms should prompt a call or emergency evaluation, and who should I contact after discharge?
Conclusion
Lead extraction removes one or more leads from inside the heart. These insulated wires connect a pacemaker or ICD to the heart, and they can be hard to remove because scar tissue forms around them.
The most common reasons for extraction are device infection, lead malfunction, breakage, recall, a lead-triggered arrhythmia, blocked blood flow and exit block. The procedure generally uses general anesthesia, a specialized sheath, real-time fluoroscopy and instruments that free the lead from scar tissue, and laser energy may sometimes be used to vaporize scar tissue.
Recovery commonly includes an overnight hospital stay, although some people stay longer. Antibiotics, lying flat after a femoral approach and a chest X-ray for newly implanted leads may be part of care. Before a planned extraction, ask the cardiac team why removal is needed, which approach is planned, whether new leads will be placed and which symptoms require urgent contact after discharge.
