What you need to know about the Intra-Aortic Balloon Pump

The most amazing organ in our body is the heart. It works without any rest, from the day we are born. But sometimes, whether due to a major heart attack, after a major surgery, or due to another serious heart condition, our heart can become very weak. At such times, the heart is unable to pump enough blood to the body. This is a very serious, even life-threatening condition. So, at times like these, we are going to talk about a special device that doctors use to give the heart a little "rest" and help it do its job.

Simply put, what is this Intra-Aortic Balloon Pump (IABP)?

Although the name sounds a bit complicated, the concept behind it is very simple. An Intra-Aortic Balloon Pump (IABP) is a long, thin balloon-like device. It is inserted into the aorta, the largest blood vessel in our body, which carries blood from the heart to the rest of the body. Think of it as a long tube-like balloon.

This balloon is not just there. It is connected to a special machine. That machine is very smart. It inflates and deflates this balloon to match the rhythm of our heart. This process makes it much easier for the weakened heart to pump blood. Usually, this device is left in the body for only a few days. That is, as a temporary support until the heart is strong enough to work on its own again.

Let's take a closer look at how this balloon pump works.

To understand this, you need to have a little idea of ​​how the heart works. Our heart is like a pump made up of two chambers.

1. When the heart contracts (Contraction/Systole): When the heart contracts, the blood inside it is pumped throughout the body through the aorta.

2. When the heart relaxes (Relaxation/Diastole): When the heart relaxes again, it fills with blood again. Pump for the next round.

Now look at how the IABP helps with this. It works exactly the opposite of the heart's process.

• When the heart contracts and pumps blood out, the balloon instantly deflates. Think of it like removing a blockage in a large pipe. Then the weak heart can pump the blood out very easily, without having to work so hard.
• When the heart expands and fills with blood, the balloon immediately inflates. This pushes the blood back into the aorta. This has two benefits. One is that more blood flows to the coronary arteries, which supply blood to the heart muscle, and the heart receives better nutrition. The other is that blood circulation to other parts of the body, especially the arms and legs, improves.

When is an IABP needed?

A doctor will decide to use this device when the patient's heart has become so weak that it is unable to supply enough blood to the body's organs. In medical terms, this condition is called "cardiogenic shock." This is a very urgent and serious condition.

The table below lists several factors that can cause cardiogenic shock.

Additionally, this IABP is used if the heart needs support after some major heart surgeries, or after a treatment such as angioplasty (Percutaneous Coronary Intervention), which opens a blocked blood vessel.

Can everyone use this?

No. This device should not be used by people with certain medical conditions because it may do more harm than good.

• Aortic Aneurysm: If the wall of the aorta is weakened and bulges like a balloon.
• Aortic Dissection: If blood has leaked between the layers of the wall of the aorta and is torn.
• Aortic Regurgitation: When the aortic valve in the heart does not close properly, causing blood to leak backward.
• Severe Peripheral Artery Disease: If the arteries that carry blood to the legs are severely blocked, it may be difficult to insert this device.
• Uncontrolled Sepsis: If there is a severe infection that has spread throughout the body.

How is the process of inserting this device into the body done?

This is usually done by cardiologists and their team, in the hospital's intensive care unit (ICU) or operating room.

Before the process

If the patient is already undergoing heart surgery, they will be under anesthesia and will not feel anything. Otherwise, if this is done separately, a local anesthetic will be given to numb the area of ​​the leg where the device will be inserted. So they will not feel any pain.

During the process

The doctor follows these steps:

1. First, a small, hollow tube called a catheter is inserted into a major artery in the groin area of ​​the leg.

2. Next, through this catheter, the deflated balloon is very carefully passed up the aorta.

3. This is done by using X-ray technology to look at the very point, that is, the aorta just below the heart.

4. Once in the right place, the outer part of the balloon is connected to the special computer. The machine then begins to control the balloon according to the heartbeat.

After the process

After the device is inserted, the patient will need to remain under special observation in the intensive care unit.

• As long as the device is in place, you should stay in bed. Keep your head slightly elevated.
• The leg with the catheter should be kept straight . If you bend it, the catheter may move around.
• To prevent blood clots, a blood thinner such as heparin is started into the vein.

What are the benefits and risks?

Like any medical treatment, this one has both benefits and risks.

However, there are some risks that can occur. It depends on factors such as the patient's age and overall health. The medical team is always aware of these risks.

Recovery and device removal

An IABP is usually left in place for only a few days . When doctors think the heart is doing a little better, they stop the pump for a while and see. Then, if the heart is working well on its own, the doctor decides to remove the device.

However, in some severe cases, if the heart is very weak, this device may need to be left in place for weeks as a bridge to another treatment, such as a heart transplant.

When to call your doctor

If you or someone close to you undergoes this type of treatment and develops any symptoms of complications after going home from the hospital, it is very important to notify your doctor immediately.
