What is an Intra-Aortic Balloon Pump (IABP)?
The Intra-Aortic Balloon Pump (IABP) is a mechanical device used in hospitals to help the heart pump blood more effectively. It is a form of temporary circulatory support used when the heart is too weak to function properly on its own.

Intra Aortic Balloon Pump Function
The IABP works on the principle of counterpulsation.
- A balloon is placed inside the aorta (the body’s main artery).
- It inflates and deflates in sync with the heartbeat.
- Inflation increases blood flow to the coronary arteries (heart’s own blood vessels).
- Deflation reduces the heart’s workload by decreasing resistance.
This simple mechanism improves oxygen supply to the heart and helps weak hearts recover.
Intra Aortic Balloon Pump Mechanism
- Inflation (Diastole): When the heart relaxes, the balloon inflates → boosts blood flow to the coronary arteries.
- Deflation (Systole): When the heart pumps, the balloon deflates → reduces pressure in the aorta, making it easier for the heart to eject blood.
👉 This timing is controlled by the ECG or arterial pressure waveform.
Indications for Intra Aortic Balloon Pump
Doctors use IABP in emergencies or critical heart conditions, such as:
- Cardiogenic Shock (heart cannot pump enough blood)
- Severe Heart Attack (Acute MI)
- Complications after Cardiac Surgery
- Unstable Angina (chest pain not responding to medicines)
- Before or After Angioplasty/Bypass Surgery
- Support during PTCA (Percutaneous Transluminal Coronary Angioplasty)
- Severe Heart Failure
👉 It is mostly a short-term life-saving support until the patient’s heart recovers or a permanent solution (like surgery or transplant) is arranged.
Intra Aortic Balloon Pump Procedure
The procedure is usually done in the ICU or cardiac catheterization lab.
- Preparation
- Patient is given mild sedation.
- Local anesthesia is applied.
- Insertion
- A catheter with a deflated balloon is inserted into the femoral artery (in the groin).
- In some cases, it can be inserted through the subclavian artery (near the shoulder).
- Positioning
- The balloon is guided into the descending thoracic aorta, just below the left subclavian artery.
- X-ray (fluoroscopy) or ultrasound confirms position.
- Activation
- The balloon pump machine is connected to the catheter.
- Balloon inflates and deflates in sync with the heartbeat.
👉 The procedure takes about 30–60 minutes.
Intra Aortic Balloon Pump Radiology
X-rays and fluoroscopy play a big role in:
- Guiding the catheter placement
- Confirming the balloon’s position in the aorta
- Checking for complications like balloon migration or arterial injury
Types of Intra Aortic Balloon Pump
- Percutaneous IABP (Most Common): Inserted through the femoral artery.
- Surgically Placed IABP: Inserted during heart surgery if the patient is unstable.
👉 All modern IABPs are controlled by advanced computerized consoles for accuracy.
How Long Can an IABP Stay in Place?
- Usually kept for 24 to 72 hours.
- In some critical patients, it may stay for up to 1–2 weeks.
- Prolonged use increases the risk of infection or blood vessel injury.
What is the Difference Between PTCA and IABP?
| Feature | PTCA (Angioplasty) | IABP (Balloon Pump) |
|---|---|---|
| Purpose | Opens blocked arteries with a balloon/stent | Supports weak heart by assisting blood flow |
| Insertion Site | Directly into blocked coronary artery | Into aorta via femoral artery |
| Duration | Permanent (with stent) | Temporary (few days) |
| Role | Fixes blockage | Supports pumping function |
Complications of IABP
While generally safe, risks include:
- Bleeding at insertion site
- Limb ischemia (reduced blood supply to legs)
- Artery injury
- Infection
- Balloon rupture (rare)
Intra-Aortic Balloon Pump Cost
The cost of IABP depends on country, hospital, and patient condition.
| Country | Average Cost (USD) | Average Cost (INR) |
|---|---|---|
| India | $2,000 – $6,000 | ₹1.5 – 5 lakh |
| USA | $20,000 – $50,000 | ₹16 – 40 lakh |
| UK | £15,000 – £25,000 | ₹15 – 25 lakh |
👉 In India, the IABP procedure is much more affordable compared to western countries.
Pros and Cons of IABP
✅ Advantages
- Improves blood supply to the heart
- Reduces heart workload
- Life-saving in emergencies
- Simple and quick to insert
❌ Disadvantages
- Temporary solution
- Risk of infection/bleeding
- Cannot be used in patients with severe aortic disease
FAQs About Intra-aortic balloon pump
1. What is the intra-aortic balloon pump used for?
It is used to support weak hearts during heart attacks, surgery, or cardiogenic shock.
2. Where is the intra-aortic balloon pump inserted?
Usually into the femoral artery in the groin, then guided into the aorta.
3. How long can an IABP stay in place?
Generally 2–3 days, sometimes up to 1–2 weeks.
4. What is the difference between PTCA and IABP?
PTCA opens blocked arteries, while IABP helps the heart pump blood temporarily.
5. What is intra-aortic balloon pump counterpulsation?
It is the technique of inflating and deflating the balloon in opposite timing to the heart’s pumping to reduce workload and improve circulation.
6. Can IABP cure heart failure permanently?
No. It is a temporary support device, not a permanent cure.
Conclusion
The Intra-Aortic Balloon Pump (IABP) is a life-saving device used in critical heart conditions. It works by reducing the heart’s workload and improving blood flow to vital organs.
