Automatic Cardioverter Defibrillator Implantation

(Implantable Cardioverter Defibrillators [ICD]; Automatic Implantable Cardioverter Defibrillator [AICD])

 

Reasons for Procedure

ICDs are implanted in patients who:
  • Have had one or more episodes of serious irregular heart rhythms
  • Have had a heart attack and are at high risk for arrhythmias
  • Have a high risk of dangerous arrhythmias
  • Have a weakened heart muscle
  • Have a high likelihood of developing an arrhythmia
  • Have the condition known as hypertrophic cardiomyopathy, which is an enlarged heart muscle that does not function properly
 

What to Expect

Prior to Procedure

The following test may be conducted prior to your procedure:
Leading up to your procedure:
  • Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure, like:
    • Anti-inflammatory drugs such as ibuprofen
    • Blood thinners
    • Anti-platelet medication
  • The night before, eat a light meal. Do not eat or drink anything after midnight.
  • Ask your doctor if you should take your daily medications with a sip of water on the day of the procedure.

Anesthesia

For the implantation of the ICD, light sedation and a local anesthesia will usually be used.
After the ICD is in place, it will need to be tested. General anesthesia will be used for this step.

Description of the Procedure

A sedative will be given by IV to help you relax. The area where the ICD is to be implanted will be washed with antiseptic. Local anesthesia will be injected to numb the area. A small incision will be made below the collarbone on the left or right side.
A wire, called a lead, will be threaded through a vein in the upper chest to the heart. An x-ray monitor will be used to watch the lead move through the vein to the heart. The signals between the heart and the ICD will be carried on this lead.
A pocket will be created under the skin at the incision site. The ICD will be implanted into the pocket.
When the ICD is in place, the sedation will be increased. The ICD will be tested to make sure that it shocks the heart appropriately. Every precaution will be taken to ensure that this is a safe process. When it is determined the ICD is working properly and in the right place, the incision will be closed with stitches.

Immediately After Procedure

You will be taken to a recovery room after the procedure. Your pulse, blood pressure, and incision site will be checked regularly. Chest x-rays will ensure the ICD and leads are in the proper place.

How Long Will It Take?

About 1-3 hours

How Much Will It Hurt?

You may feel some pushing and tugging on the skin during the procedure. The anesthesia should minimize any pain. After the procedure, you may experience some pain or stiffness at the incision site. Pain medication may be prescribed.

Average Hospital Stay

1-3 days

Postoperative Care

At the Hospital
The day after your implant, you will have an ECG and blood tests. The ICD function may be checked again. This will require sedation.
At Home
Do the following to help ensure a smooth recovery:
  • You may need to avoid:
    • MRI scans
    • Heat therapy, which is often used in physical therapy
    • High-voltage or radar machinery, such as electric arc welders, high-tension wires, radar installations, or smelting furnaces
    • Contact with radio or television transmitters
    • Prolonged contact with household appliances, such as microwave ovens
  • Do not carry a cell phone in a pocket directly over the device. Keep your phone on the side away from the device. Also, headphones worn with MP3 players may cause interference.
  • Turn off car or boat motors when working on them. They may temporarily confuse your device.
  • Tell your doctor or dentist that you have a device before a surgical procedure.
  • Check with your doctor about the safety of going through airport security detectors with your particular device. Do not linger in security devices.
  • Be sure to follow your doctor’s instructions.
You will get an ID card that contains important information about your ICD. It is important that you show this card to any doctor, nurse, dentist, or other healthcare professional at the beginning of an office visit or hospital admission.
If your heart requires a shock from your ICD, you may be able to feel it. You may feel lightheaded before the shock. This is from the heart rhythm. The shock administered by the ICD may feel like a light thump or a strong kick in the chest. If you feel a shock, try to stay calm and sit or lie down. If someone is with you, ask him or her to stay. If you feel okay after the shock, contact your doctor’s office to let them know. This is not an emergency. Your doctor may want you to come in for a check-up, particularly if this is the first shock you have received. If you receive multiple shocks in a row or multiple shocks in a day, you should go to the emergency room.
