What is Coronary Artery Bypass Grafting (CABG)?
Coronary Artery Bypass Grafting (CABG) is an open-heart surgical procedure performed to restore normal blood flow to the heart muscle when coronary arteries become blocked or severely narrowed due to plaque buildup (atherosclerosis).
During CABG surgery, the cardiac surgeon creates a new pathway for blood to reach the heart by using healthy blood vessels taken from another part of the body — usually the Internal Mammary Artery (IMA), Radial Artery (arm), or Great Saphenous Vein (leg). The surgery improves blood circulation, relieves chest pain (angina), reduces the risk of heart attacks, improves heart function, and significantly enhances quality of life.
India has become one of the world's leading destinations for CABG surgery because of its internationally trained cardiac surgeons, advanced heart institutes, high success rates, affordable treatment costs, and internationally accredited hospitals. Every year, thousands of patients from Bangladesh, Kenya, Tanzania, Uganda, Ethiopia, Nigeria, Iraq, Oman, Nepal, Mauritius, Zambia, Zimbabwe, Ghana, and other countries travel to India for affordable and world-class cardiac care.
Who Needs Coronary Artery Bypass Grafting (CABG)?
Your orthopedic surgeon may recommend this procedure if you have:
- Triple Vessel Disease (TVD)
- Left Main Coronary Artery Disease
- Severe Coronary Artery Disease (CAD)
- Multiple blocked coronary arteries
- Failed angioplasty or recurrent stent blockage
- Diabetes with multivessel coronary disease
- Severe angina not controlled with medicines
- Reduced heart pumping function due to blocked arteries
- Heart attack requiring emergency bypass surgery
- Complex coronary artery blockages unsuitable for stenting
Common Causes
Symptoms
- Chest pain (angina)
- Shortness of breath
- Chest heaviness
- Fatigue
- Pain radiating to the arm, neck, jaw, or back
- Sweating
- Dizziness
- Palpitations
- Reduced exercise tolerance
- Heart attack
Diagnosis
- Coronary Angiography
- ECG
- 2D Echocardiography
- Cardiac CT Scan (selected cases)
- Chest X-ray
- Complete Blood Count (CBC)
- Kidney Function Tests
- Liver Function Tests
- Blood Sugar (HbA1c)
- Lipid Profile
- Coagulation Profile
- Pulmonary Function Tests (if required)
- Carotid Doppler (selected patients)
- Dental evaluation (if indicated)
- Anesthesia assessment
Types of Coronary Artery Bypass Grafting (CABG)
Conventional CABG (On-Pump Surgery)
The most common procedure, performed using a heart-lung bypass machine while the heart is temporarily stopped.
Off-Pump CABG (Beating Heart Surgery)
Performed while the heart continues beating without using a heart-lung machine — offering less bleeding, faster recovery, and lower stroke risk in selected patients.
Minimally Invasive Direct Coronary Artery Bypass (MIDCAB)
Performed through a small incision without opening the entire chest. Suitable only for selected patients.
Total Arterial CABG
Uses only arterial grafts for better long-term durability.
Robotic-Assisted CABG
Performed using robotic technology through tiny incisions with enhanced precision and quicker recovery in carefully selected patients.
Benefits
- Restores blood flow to the heart
- Relieves chest pain
- Reduces heart attack risk
- Improves survival in selected patients
- Better long-term outcomes than PCI in certain multivessel disease
- Improves heart function
- Increases exercise capacity
- Enhances quality of life
- Long-lasting results
- Reduces dependence on medications in many patients
The Procedure
- Pre-operative evaluation and surgical planning
- Administration of general anesthesia
- Midline chest incision (sternotomy) or minimally invasive approach
- Harvesting healthy blood vessels from the chest, leg, or arm
- Connection to heart-lung machine (if required)
- Creation of bypass grafts around blocked arteries
- Restoration of normal blood flow
- Heart function assessment
- Closure of the breastbone using surgical wires
- ICU monitoring and recovery
Duration: The surgery usually takes 3 to 6 hours, depending on the number of bypass grafts.
Recovery Timeline
Success Rate
In experienced Indian cardiac centers, CABG surgery has a success rate exceeding 95–98% in appropriate candidates. Overall outcomes depend on the patient's age, number of blocked arteries, heart pumping function (LVEF), diabetes, kidney function, surgical expertise, hospital infrastructure, and post-operative care, so results vary based on individual risk factors.
Risks
Although coronary artery bypass grafting (cabg) is generally safe, possible risks include:

Frequently Asked Questions
CABG is a surgical procedure that bypasses blocked coronary arteries using healthy blood vessels from another part of the body to improve blood flow to the heart.
It depends on the patient's condition. CABG is often preferred for complex multivessel disease, left main coronary artery disease, and many patients with diabetes, while angioplasty may be suitable for selected blockages.
The procedure generally takes 3–6 hours, depending on the number of grafts and surgical complexity.
Arterial grafts can remain functional for 15–20 years or longer, while vein grafts often last 10–15 years, depending on lifestyle and medical management.
Patients receive general anesthesia during surgery. Some discomfort after the procedure is expected and is managed with pain medications.
Most patients stay in the hospital for 5–8 days, depending on recovery.
International patients are generally advised to remain in India for 2–3 weeks after surgery for follow-up and recovery before flying home.
Yes. Most patients return to normal daily activities after completing recovery and cardiac rehabilitation, while maintaining a heart-healthy lifestyle.
Yes. Most patients continue medications such as antiplatelets, statins, and blood pressure medicines as advised by their cardiologist.
