Everyone gets a little nervous when they hear about a machine inside their chest, right? That's normal. But do you know how much these little machines help millions of people with heart failure live healthy and long lives? These are very important medical devices that help save lives. Today we are talking about these heart-assisting devices, that is, Cardiac Assist Devices. Let's get rid of the fear and doubt about this and simply understand these things.
What are these cardiac assist devices?
Simply put, this is a small device that your doctor can implant in your chest to help your heart function better. This device comes to your aid when your heart needs a boost.
Imagine, some people's heartbeats become irregular. We call it ``Arrhythmia''. In such cases, these devices can help regulate the heartbeat, prevent sudden cardiac arrest, or help the heart pump blood throughout the body.
You may be a little uncomfortable with the idea of having a machine inside your chest, but remember that millions of people around the world rely on these devices to live healthier and longer lives.
What are the main types of these devices?
There are several main types of devices that help the heart. The doctor chooses the most suitable device based on the needs of each individual. Let's look at the main types.
| Device Type | Simply put, what does it entail? |
|---|---|
| Pacemaker | This tells the heart muscle, "Here, beat at this time." That is, it sends out small electrical signals to keep the heart rate at the right level for someone whose heart rate is too fast. |
| Biventricular Pacemaker | Its wires are connected to the two lower chambers of the heart (ventricles) and the right upper chamber (atrium), causing all of these chambers to work together, in the same rhythm. |
| Implantable Cardioverter Defibrillator (ICD) | If the heart rate becomes dangerously fast, this device can detect it and deliver a small electric shock to bring it back into the correct rhythm. This protects against sudden death. |
| Ventricular Assist Device (VAD) | This machine helps the heart pump blood throughout the body. It's like an assistant that reduces the workload of the heart. It's used for people whose hearts are very weak. |
Why is such a device needed?
There are several reasons why your doctor might recommend a device like this. The main ones are to regulate the heart's rhythm, prevent sudden cardiac arrest, or improve pumping ability.
If there is any weakness in the functioning of the heart, it is your doctor who will determine the exact cause and determine the most appropriate device.
These devices may be needed by people with the following medical conditions:
- Heartbeat irregularities `(Arrhythmia)`
- Heart Block
- Problems with the heart's natural pacemaker (sinus node) (Sick Sinus Syndrome)
- Long QT Syndrome (long QT syndrome)
- Rapid heartbeat (Tachycardia)
- Excessively slow heartbeat (Bradycardia)
- Ventricular Fibrillation, a dangerous, life-threatening heart rhythm disorder
- Heart Failure: The inability of the heart to pump enough blood to the body.
- Cardiomyopathy (heart muscle diseases)
How do these devices work?
Imagine that your doctor carefully places a device, such as a pacemaker or ICD, under the skin of your chest. Then, they attach thin wires (leads) from it to specific locations in your heart. These wires allow the device to 'listen' to your heart's activity and to send electrical signals to correct your heart rate when needed. An ICD can also deliver an electric shock if needed.
These devices operate according to a program set up externally by the doctor. They have a small, long-lasting battery .
Another great thing is that some devices can collect information about your heart and send it to your doctor via phone or the internet. So, even without going to the hospital regularly, your doctor can be aware of the condition of your heart. This can be a great help in identifying any changes before they get worse.
What are the benefits of using these devices?
- Life-saving protection from sudden cardiac arrest.
- Better blood circulation in the body.
- Regularization of the heartbeat rhythm.
- Reduction in heart rate-related symptoms (such as dizziness, fatigue).
- Reduced hospitalizations due to heart disease.
- Some devices can be implanted through a very small incision, rather than a large incision .
- The device's battery lasts for a long time , from 6 to 15 years .
What are the possible risks or side effects?
As with any medical procedure, there are some very small risks involved. However, it is important to remember that these are very rare and that doctors are very careful about this.
- Bleeding.
- A very small hole in the heart may form when the device is inserted (this is very rare).
- Pneumothorax.
- Blood clotting.
- Damage or breakage of the device's wires.
- Device malfunction.
- Moving the device.
- Device-related infections.
If something like this happens, your medical team is always ready to provide the necessary treatment.
How should I be careful when living with a device?
After the device is implanted, you can go about your daily life as normal. However, there are a few things to keep in mind.
| Fact | What to do |
|---|---|
| Cutting Road | Follow the doctor's instructions on how to care for your incision. |
| Exercise and work | You will need to limit activities such as lifting heavy objects in the beginning. Ask your doctor when you can start driving and going to work again. |
| MRI scan | If you need to have an MRI scan, be sure to talk to your doctor. Most people who have the equipment can do an MRI, but your doctor will need to be aware of any special precautions you need to take to make it safe. |
| Everyday accessories | Everyday items like mobile phones, microwave ovens, and security scanners usually don't cause any problems. Don't worry about that. |
| Call your doctor if you have these symptoms: | |

You should see your doctor at least once a year (more often in the beginning) to make sure the device is working properly. Also, don't hesitate to call your doctor anytime you feel anything strange or uncomfortable.
