Heart disease continues to rank as the world’s leading cause of death, with coronary artery disease (CAD) representing its most prevalent form. Cardiovascular diseases are responsible for an estimated 19.8 million deaths worldwide each year, with more than four out of five of these deaths resulting from heart attacks and strokes.
For many patients dealing with severe or multiple blocked arteries, medication or stenting alone may not be sufficient. In these situations, coronary artery bypass grafting (CABG) offers an effective path forward. Patients seeking coronary artery disease surgery in Ahmedabad can consult specialists at SGVP Holistic Hospital, where treatment plans are tailored according to the severity of coronary artery disease and the patient’s overall health.
CABG can be performed using different surgical techniques depending on the patient’s condition, the number and location of blocked arteries, and the surgeon’s assessment. This article focuses on conventional open-heart CABG surgery, which remains one of the most commonly performed approaches for treating complex coronary artery disease.
What is CABG Surgery?
CABG surgery (coronary artery bypass grafting) is a procedure that restores blood flow to the heart by creating a new pathway around blocked coronary arteries. It improves the supply of oxygen-rich blood to the heart muscle, helping relieve symptoms such as chest pain (angina), reducing the risk of future cardiac events, and improving overall heart function.
CABG is recommended when one or more coronary arteries become narrowed or blocked due to the buildup of fatty deposits (plaque). Rather than removing the blockage, the surgeon uses a healthy blood vessel from another part of the body to create a bypass around the affected artery, allowing blood to flow more freely to the heart muscle.
CABG can be performed using different surgical techniques depending on the patient’s condition and the complexity of coronary artery disease. In conventional open-heart CABG surgery, the surgeon accesses the heart by dividing the breastbone (sternum).
During this procedure, the heart may be temporarily stopped and connected to a heart-lung machine, or the operation may be performed on the beating heart (off-pump CABG), depending on the surgical approach.
The bypass graft may be created using:
- The internal mammary artery from the chest
- The radial artery from the forearm
- The saphenous vein from the leg
The number of grafts required depends on how many coronary arteries are blocked. Patients may undergo a single, double, triple, or quadruple bypass procedure.
The goals of CABG surgery are to:
- Improve blood flow to the heart muscle
- Relieve symptoms such as angina and shortness of breath
- Lower the risk of a heart attack
- Improve quality of life
- Increase long-term survival in appropriately selected patients
When is CABG Surgery Recommended?
Doctors recommend CABG surgery when blocked coronary arteries significantly reduce blood flow to the heart, and other treatments are unlikely to provide lasting benefit. The decision depends on the number of blocked arteries, their location, symptom severity, and the patient’s overall health.
CABG is not the first treatment for every patient with coronary artery disease. Many people initially receive lifestyle advice, medications, or angioplasty with stent placement. Surgery is considered when these approaches cannot adequately restore blood flow or when long-term outcomes are expected to be better with bypass surgery.
Conditions That May Require CABG
CABG is recommended for patients with severe coronary artery disease, especially when multiple arteries are affected or critical vessels are involved.
Doctors may advise surgery in situations such as:
- Significant narrowing of the left main coronary artery
- Triple-vessel coronary artery disease
- Multiple blocked arteries with reduced heart function
- Persistent angina despite optimal medications
- Failed or recurrent blockage after angioplasty or stenting
- Certain patients with diabetes and extensive coronary artery disease, for whom CABG has shown better long-term outcomes than stenting
The recommendation is based on coronary angiography findings, heart function, age, other medical conditions, and individual surgical risk.
Who May Benefit from CABG Surgery?
Patients with complex coronary artery disease generally experience the greatest benefit from CABG surgery. Careful evaluation helps determine whether surgery offers the best long-term outcome.
People who may benefit include those with:
- Diabetes and multiple blocked arteries
- Reduced pumping ability of the heart (low ejection fraction)
- Extensive coronary artery disease affecting several vessels
- Recurrent symptoms despite medications or previous stenting
- Blockages that are difficult to treat with angioplasty alone
An experienced cardiac surgeon in Ahmedabad at SGVP Holistic Hospital works alongside cardiologists to evaluate angiography findings, overall health, and patient preferences before recommending the most appropriate treatment approach.
What Happens During the CABG Surgery Procedure?
The following steps describe conventional open-heart CABG surgery, the most widely performed form of coronary artery bypass surgery for patients with complex coronary artery disease. The operation involves creating new pathways for blood to reach the heart by bypassing blocked coronary arteries. It is performed under general anaesthesia and usually takes three to six hours.
1. Preparing for Surgery
Before surgery, the healthcare team conducts several tests to evaluate the patient’s heart and overall health. These may include:
- Blood tests
- Electrocardiogram (ECG)
- Echocardiogram
- Coronary angiography
- Chest X-ray
Patients are advised to stop eating and drinking several hours before surgery. The anaesthesiologist also reviews the patient’s medical history and current medications.
2. Administering General Anaesthesia
The patient receives general anaesthesia before the procedure begins. This ensures they remain asleep, pain-free, and unaware throughout the surgery. A breathing tube is inserted and connected to a ventilator to support breathing during the operation.
3. Accessing the Heart
During open-heart CABG, the surgeon makes an incision along the centre of the chest and divides the breastbone (sternum) to access the heart. This approach provides a clear view of the coronary arteries and allows multiple bypass grafts to be performed safely when required.
4. Harvesting the Graft
A healthy blood vessel is removed from another part of the body to create the bypass.
Common grafts include:
- Internal mammary artery from the chest
- Radial artery from the forearm
- The saphenous vein from the leg
Arterial grafts generally remain open longer than vein grafts and may be preferred when suitable.
5. Creating the Bypass
In conventional open-heart CABG, the surgeon may temporarily connect the patient to a heart-lung machine (cardiopulmonary bypass), which maintains blood circulation and oxygen supply while the heart is temporarily stopped.
Some patients may undergo off-pump CABG, where the heart continues beating during surgery. The most suitable technique depends on the patient’s condition and the surgeon’s assessment.
The surgeon then attaches one end of the graft above the blockage and the other end below it, creating a new route for blood to reach the heart muscle.
6. Completing the Procedure
Once all grafts are in place, the heart is restarted if it was temporarily stopped. The surgeon checks that each graft is functioning properly before closing the breastbone with surgical wires and suturing the skin.
Patients considering CABG treatment in Ahmedabad can discuss different surgical approaches with the multidisciplinary cardiac team at SGVP Holistic Hospital, where treatment decisions are based on each patient’s clinical condition.
Open-Heart CABG Surgery at a Glance

What Are the Risks of CABG Surgery?
Open-heart CABG is considered a safe and effective procedure, but like any major surgery, it carries certain risks. The likelihood of complications depends on factors such as age, overall health, heart function, and existing medical conditions.
Most patients recover without major problems, particularly when surgery is planned rather than performed as an emergency.
Possible complications include:
- Bleeding requiring transfusion or additional surgery
- Infection at the chest or leg incision site
- Irregular heart rhythm (atrial fibrillation)
- Stroke
- Heart attack during or shortly after surgery
- Kidney dysfunction
- Blood clots
- Lung infections
- Temporary memory or concentration difficulties
The risk is generally higher in older adults and those with diabetes, chronic kidney disease, or severe heart failure. Following medical advice before and after surgery helps minimise these risks.
How Much Does CABG Surgery Cost in India?
The CABG surgery cost in India varies depending on the hospital, city, complexity of the surgery, and the patient’s medical condition. Insurance coverage and postoperative care requirements also influence the final expense.
The average CABG surgery cost in India generally ranges from ₹2.5 lakh to ₹6 lakh, although complex cases or premium hospitals may charge more.
Factors Affecting Cost
| Factor | Impact on Cost |
| Hospital type | Private hospitals generally charge more than government hospitals |
| Number of bypass grafts | More grafts increase surgical complexity |
| ICU and hospital stay | Longer stays increase overall expenses |
| Additional medical conditions | May require extra investigations or treatments |
| Location | Costs vary between cities |
Patients seeking treatment at a heart hospital in Ahmedabad, such as SGVP Holistic Hospital, should discuss detailed cost estimates, insurance coverage, and postoperative rehabilitation with their healthcare team before surgery.
What Is Recovery Like After CABG Surgery?
Recovery after open-heart CABG surgery begins in the intensive care unit and continues for several weeks at home. Because the breastbone needs time to heal after open-heart surgery, complete recovery generally takes longer than after minimally invasive procedures.
Recovery in the Hospital
Immediately after surgery, patients are transferred to the intensive care unit (ICU), where their heart rhythm, blood pressure, breathing, and oxygen levels are continuously monitored.
Most patients:
- Spend one to two days in the ICU
- Remain in the hospital for five to seven days
- Begin walking within 24-48 hours
- Start breathing exercises to prevent lung complications
Pain around the incision is expected but is managed with medications.
Recovery at Home
Healing continues after discharge. Patients are encouraged to gradually increase physical activity while avoiding heavy lifting until the breastbone heals.
Doctors generally recommend:
- Walking every day
- Eating a heart-healthy diet
- Taking prescribed medications regularly
- Attending follow-up appointments
- Participating in cardiac rehabilitation
CABG Surgery Post Op Care
Proper CABG surgery post-op care reduces the risk of complications and supports long-term recovery.
Patients should:
- Keep the surgical wound clean and dry
- Watch for redness, swelling, or drainage
- Monitor blood sugar if diabetic
- Control blood pressure and cholesterol
- Stop smoking completely
- Maintain a healthy body weight
- Report fever, chest pain, or shortness of breath immediately
Cardiac rehabilitation programmes also help patients regain strength, improve heart health, and reduce future cardiovascular risk.
Frequently Asked Questions (FAQs)
Most CABG procedures take between three and six hours. The duration depends on the number of blocked arteries, the type of bypass performed, and whether additional cardiac procedures are required during the same operation.
Patients do not feel pain during surgery because they receive general anaesthesia. Some discomfort around the chest incision is expected after the operation, but pain medications help manage it effectively while the body heals.
Arterial grafts, particularly those using the internal mammary artery, can remain open for several decades. Vein grafts may have a shorter lifespan, but maintaining a healthy lifestyle and taking prescribed medications improves long-term graft function.
Many patients resume light daily activities within four to six weeks. Returning to work, driving, or strenuous exercise depends on individual recovery, the type of work performed, and the surgeon’s recommendations.
Yes. Although CABG restores blood flow, new blockages can develop over time if cardiovascular risk factors remain uncontrolled. Quitting smoking, eating a balanced diet, exercising regularly, and taking medications significantly reduce this risk.
Yes. Most patients continue taking medications after surgery to protect the heart and reduce the risk of future cardiovascular events. These may include antiplatelet drugs, statins, blood pressure medications, and medicines for diabetes when required.
Bypass surgery is one type of open-heart surgery, but not every open-heart surgery is a bypass procedure. Open-heart surgery refers to any operation where surgeons access the heart through the chest, including valve repair or replacement, congenital heart defect correction, heart transplantation, tumour removal, and coronary artery bypass grafting (CABG).
CABG surgery has a high success and survival rate. In elective (planned) procedures, more than 95-98% of patients survive the operation, although the exact outcome depends on individual health factors and the complexity of the surgery. Survival is influenced by age, heart function, diabetes, kidney disease, lung disease, and whether the surgery is performed as an emergency.
