What is CABG? Understanding Coronary Artery Bypass Surgery in India
Coronary Artery Bypass Grafting (CABG) is one of the most commonly performed heart surgeries worldwide. In India, it has become a cornerstone of cardiac care, offering advanced surgical options with high success rates at a fraction of global costs. This article explores what CABG involves, who needs it, what the recovery looks like, and why thousands of patients are choosing India as their destination for this life-saving procedure.
What is CABG?
CABG is a surgical procedure used to treat coronary artery disease (CAD), a condition where the arteries supplying blood to the heart become narrowed or blocked. The goal of CABG is to restore normal blood flow to the heart by bypassing the blocked section of the artery using a healthy blood vessel taken from the leg, arm, or chest.
How it Works:
- Surgeons create a new pathway (graft) around blocked arteries.
- Grafts are usually taken from the saphenous vein (leg), radial artery (arm), or internal mammary artery (chest).
- The procedure may involve multiple bypasses, depending on the number of blocked arteries.
CABG is typically performed as an open-heart surgery under general anesthesia. In some Indian hospitals, minimally invasive or robotic CABG (beating-heart surgery) is also available.
Who Needs CABG?
CABG is recommended for patients with:
- Severe blockages in multiple coronary arteries
- Persistent chest pain (angina) that doesn’t respond to medication or angioplasty
- Left main coronary artery disease
- Poor heart function due to ischemia
- Diabetes with multi-vessel coronary disease
CABG in India: Why It’s a Global Hub
India has emerged as a medical tourism hub for CABG due to the combination of world-class medical expertise, affordability, and comprehensive care. Leading hospitals in cities like Chennai, Delhi, Bangalore, and Mumbai offer CABG with international standards.
Key Advantages:
- Internationally trained cardiac surgeons
- State-of-the-art facilities including cardiac ICUs and robotic operating suites
- Cost savings of up to 70–80% compared to the US or Europe
- Shorter waiting times and fast-tracked surgical scheduling
- English-speaking medical staff and multilingual support for international patients
Pre-Surgical Evaluation
Before CABG, patients undergo a comprehensive evaluation that includes:
- Coronary angiography
- ECG and echocardiogram
- Chest X-ray and blood tests
- Risk assessment and anesthesia clearance
Hospitals often assign a multi-disciplinary team to assess fitness for surgery and guide the patient through the entire process.
The CABG Procedure: Step-by-Step
- Anesthesia & Incision: The patient is given general anesthesia. A midline chest incision is made to access the heart.
- Harvesting Grafts: Surgeons collect graft vessels from the leg, chest, or arm.
- Bypass Creation: Using a heart-lung machine (or off-pump technique), surgeons attach the graft vessels above and below the blockage.
- Closing the Incision: The chest is closed using wires and sutures.
The surgery takes about 3–6 hours, depending on complexity.
Recovery After CABG
In-Hospital Stay:
- 1–2 days in ICU for monitoring
- 5–7 days in general cardiac ward
- Early ambulation and breathing exercises start within 24–48 hours
Home Recovery:
- 6–12 weeks total recovery period
- Restrictions on driving, lifting, and strenuous activity
- Cardiac rehabilitation including physiotherapy, nutrition, and lifestyle counseling
Follow-Up Care:
- Regular consultations for medication management
- Repeat echocardiograms to monitor heart function
Indian hospitals often provide virtual follow-up consultations for international patients.
Risks and Success Rates
CABG is a major surgery, but with high success rates — especially in high-volume cardiac centers. Common risks include:
- Bleeding
- Infection
- Irregular heartbeat
- Stroke or heart attack (rare)
Indian cardiac centers report success rates of 95–98%, depending on the patient’s overall health and complexity of disease.

Cost of CABG in India
Prices vary based on hospital, city, and patient condition but typically range between INR 1.5 to 4 lakhs (USD $1,800–$5,000). This includes:
- Pre-operative investigations
- Surgery and hospital stay
- ICU and cardiac monitoring
- Post-op medication
