Have you ever had a pacemaker or an ICD (Implantable Cardioverter Defibrillator), a small device that helps keep your heart beating properly? If so, you probably know that after a while, you'll need to replace parts like the battery. Many people get a little nervous when they hear about this. It's normal to think things like, "Will I have to have another surgery? Will it be difficult?" But it's actually not as scary as we think. Today, let's talk about replacing these heart devices in a simple way.
What does it mean to replace a heart device?
Simply put, this is also a surgery. But it involves replacing the electronic device (Cardiac Implantable Electronic Device - CIED) that is already implanted to control your heart's rhythm with a new one. There are two types of these devices. One is a pacemaker . The other is an ICD (Implantable Cardioverter Defibrillator) .
Most of the time, this is a minor surgery that doesn't require a hospital stay and you can go home the same day . So there's no need to worry too much about it.
Who would want to replace a device like this?
The main reason for replacing a heart device is when its battery is low. It's like the battery in our phone running low. The battery in such a device can usually be used for between 6 and 10 years . Therefore, it may have to be replaced several times during a lifetime.
But don't worry about this. Your doctor will regularly check the battery level of this device when you go to the clinic. So they will let you know in advance when the battery is about to run out.
In addition to the battery running out, there are several other reasons why you might need to replace these devices. Let's take a look at what they are.
| Reason | Description |
|---|---|
| Battery running out | This is the most common and main reason. When the battery is weak, the device has to be replaced. |
| Device upgrade | Your doctor may recommend a newer, more capable device than the one you currently have. |
| Equipment errors | If the implanted device develops a technical fault or completely stops working, it will have to be replaced. |
| Infectious conditions | Very rarely, if an infection develops around the device, it may need to be removed. This is not seen very often. |
What happens before the surgery?
Your doctor will give you specific instructions on how to prepare for this surgery. These instructions may include:
- Stopping certain medications: You may be asked to stop taking blood thinners (for example, aspirin ) and some painkillers for a few days.
- Heart tests: Something like an ECG (Electrocardiogram) or an Echocardiogram scan may be done to check the function of the heart.
- Blood tests: Several blood tests will be done to see if you are in good health for the surgery.
What happens during the surgery?
The best part is that most of the time, this surgery only replaces the part of your body called the generator that contains the battery, which is under your skin. This means that the leads connected to your heart are not removed. This makes it a minor operation rather than a major one.
However, in some cases, you may need to replace the entire device, including the wires. That's a slightly more complicated process .
What happens when replacing a regular generator:
1. First, you will be given a mild sedative (sedation) through a vein in your arm. You will not feel any pain.
2. Then, a small incision is made in the skin where the device will be implanted.
3. The old generator is removed by unplugging the wires.
4. The new generator is plugged into the same place and connected to the same wires as the old one.
5. Finally, the incision is closed with stitches or a special type of glue .
What are the benefits and risks of this?
As with any medical treatment, there are benefits and very minor risks.
| Benefits | Risks |
|---|---|
| The device operates at maximum efficiency. | Allergy to sedatives. |
| Preventing abnormal, dangerous heart rhythms. | Excessive bleeding or blood clotting. |
| Maintaining good heart health and protecting life. | Infection around the incision or wire (if the wire is changed). |
The most important thing is that this is a very safe, low-risk surgery . The complications are very rare.
When should I talk to the doctor during recovery?
You will need to stay in the hospital for a few hours after the surgery. The staff will monitor you and if everything is fine, you will be sent home the same day. After you go home , you should avoid doing anything heavy, such as exercising, for a few days. It is normal for the incision to be a little swollen and sore. The doctor will give you painkillers for that.
Additionally, your doctor will give you instructions on how to keep the incision clean, how to care for the new device, and when you can resume normal activities.
However, if you experience the following symptoms, you should contact your doctor immediately.
| Seek medical advice immediately. | |
|---|---|
| If you have these symptoms: | |
| Chest pain | Fever or body aches |
| Difficulty breathing (Dyspnea) | Signs of infection, such as pus, odor, or redness from the incision |
| If you suspect that the device is not working properly (if you have these symptoms): | |
| Dizziness | Loss of consciousness (fainting) |
| Feeling like your heart is beating fast or slow | Persistent hiccups |
Extremely important: If you experience severe chest pain, severe difficulty breathing, or fainting , go to the nearest hospital Emergency Department (ETU) immediately.
