What is an Implantable Cardioverter Defibrillator (ICD) insertion?

An Implantable Cardioverter Defibrillator (ICD) insertion is a procedure to place a small device under the skin in your chest. The ICD monitors heart rhythms and can deliver electrical shocks to restore a normal heartbeat if a dangerous arrhythmia is detected.

What happens during an Implantable Cardioverter Defibrillator (ICD) insertion?

During ICD insertion, the surgeon makes a small incision in the chest.
Leads are threaded through a vein to the heart and connected to the ICD.
The ICD is placed under the skin in the upper chest and the incision is closed.
The procedure typically takes 1 to 2 hours.

Why would I need an Implantable Cardioverter Defibrillator (ICD) insertion?

You might need an ICD if:

• You have a history of life-threatening arrhythmias such as ventricular tachycardia
  or ventricular fibrillation.

• You have survived a sudden cardiac arrest.

• You are at high risk of sudden cardiac death due to heart disease.

Who needs an Implantable Cardioverter Defibrillator (ICD) insertion?

ICD insertion may be necessary for:

• Patients with a history of severe heart arrhythmias.

• Individuals with a high risk of sudden cardiac arrest.

• Those with weakened heart muscle or certain genetic conditions that increase the risk of dangerous arrhythmias.

What are the risks of an Implantable Cardioverter Defibrillator (ICD) insertion?

ICD insertion involves some risks, including:

• Infection at the implantation site.

• Bleeding or bruising.

• Lead displacement or malfunction.

• Rarely, is damage to blood vessels or the heart.

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.


How do I prepare for an Implantable Cardioverter Defibrillator (ICD) insertion?
To prepare for ICD insertion:

• Follow your doctor’s instructions, which may include fasting for several hours before the procedure.

• Inform your provider of any allergies and medications you are taking.

• Arrange for someone to drive you home after the procedure, as you may be sedated.

• Wear comfortable clothing and remove any jewelry or metal objects.
