An ICD is a small device that sends a strong electrical shock to your heart if you have an abnormal, life-threatening rhythm. The shock helps to restore an unsafe heart rhythm back to normal. The ICD can pace your heart if needed. An ICD has two parts, a battery (generator) and the lead(s). Leads are wires that connect the generator to your heart tissue.
This is a traditional ICD that is placed under the skin just below the collarbone. The lead(s) go inside your heart. The number of leads can vary. You may have:
1 lead (Single chamber ICD)
2 leads (Dual chamber ICD)
3 leads (Cardiac resynchronization therapy defibrillator, also called CRT-D)
The Day Before Surgery
A nurse will call you the day before surgery (or the Friday before a Monday surgery). The nurse will review your instructions and tell you what time to arrive. If you do not hear from us by 4 pm, please call 608-263-1530.
If you feel sick or have a fever over 100°F the day before surgery, call the clinic.
The Day of Surgery
Before the procedure starts blood may be drawn for labs. You will have an IV placed in your hand or arm. If needed, a small area around the surgical sites will be shaved. Your skin will be cleaned with a special soap. You may receive antibiotics through your IV to help prevent infection.
You will receive medicine to make you comfortable. Your skin will be numbed around the incision site.
Sterile drapes will cover you from your neck to your feet so that only the surgical site is exposed.
The vein below your collarbone is used because it travels to your heart. A small “pocket” is made under your skin for the new device generator and lead(s) to sit in. The leads are then threaded through the blood vessel into the heart, using x-ray for guidance. Once the lead(s) is/are in the right place, they are secured. Then, the lead(s) is/are connected to the generator (which contains the battery). The site is closed with dissolvable sutures or surgical glue. The whole process takes about 1-3 hours.
You may go home the same day or stay in the hospital overnight. Your device will be checked before you leave and you may have an x-ray. We will review discharge instructions with you.
You cannot drive yourself home. You need to arrange for someone to drive you home. You may resume driving after 1 week. In some cases, it may be more than one week depending on what your physician recommends.
When a device is first implanted or there are new leads added, you will have restrictions. This allows the device/leads to fully heal in the heart. The restrictions help make sure the device does not dislodge and the leads do not move as healing occurs. Some
restrictions vary by person based on the reason you received the device. The most common guidelines are:
Do not swim, golf, play tennis, or any other contact sports for 3 months.
Avoid dental work for 1 month.
For 6 weeks after surgery:
Do not raise your arm over your head on the side of your device.
Do not reach behind you on the side of your device.
Do not lift more than 10 pounds (i.e. a gallon of milk) with the arm on the side of your device.
You may want to wear your arm in a sling when you sleep for the first 1-2 weeks. This will help prevent involuntary motions while you sleep.
It is important that you take care of your incision site to prevent an infection.
Keep the site clean and dry
Do not use any lotions or ointments on the incision. Do not scratch or rub the site.
Do not soak in a bathtub, hot tub, or go into a pool, lake, or river until your incision is completely healed.
Leave the current bandage on for 72 hours.
Do not shower for _____days.
Your incision may have clear glue or small pieces of tape called “steri-strips” under the bandage. If there are steri-strips in place, leave them until they fall off on their own. The nurse may also remove them at your follow-up visit.
When you do shower, let the soap and water run down the incision and gently pat dry.
Look at the site daily for signs of infection:
Fever (101°F or higher)
Warm to touch
You may take a mild pain reliever such as acetaminophen (Tylenol®) or ibuprofen (Motrin®) for any pain. You may also apply an ice pack. Ibuprofen or other NSAID medicines increase your risk of bleeding. You may want to avoid them if you are taking a blood thinner.
Device ID Card
You will receive a temporary ID card and will receive your permanent card in about 2 months. Carry your card with you all the time. Tell your health and dental care providers that you have a permanent cardiac device.
You will need to avoid certain types of electrical devices. For more information, call your device company.
