1. Overview of CABG

Coronary Artery Bypass Grafting (CABG), commonly known as heart bypass surgery, is a life-saving procedure that restores blood flow to the heart muscle. It creates a new route for blood to travel around blocked or narrowed coronary arteries, bypassing the obstruction.

Coronary artery disease (CAD) is the most common type of heart disease. It occurs when the coronary arteries—the blood vessels that supply oxygen-rich blood to the heart—become narrowed or blocked by a buildup of plaque (atherosclerosis). When blood flow to the heart is significantly reduced, it can cause chest pain (angina), shortness of breath, and increase the risk of a heart attack. Learn more about CABG heart bypass medical terms.

During a CABG procedure, a surgeon takes a healthy blood vessel from another part of the body—such as the chest, leg, or arm—and uses it to create a detour around the blocked artery. This restores normal blood flow to the heart muscle, relieving symptoms and improving overall heart function. Learn about heart bypass operation time and CABG surgery duration.

CABG is one of the most commonly performed cardiac surgeries worldwide, with success rates of 95 to 98 percent at established cardiac centres[reference:0]. It provides both symptomatic relief and prognostic benefits for patients with severe coronary artery disease[reference:1].

Learn more about CABG from the American Heart Association.

2. What Is Coronary Artery Bypass Grafting?

Coronary artery bypass grafting (CABG) is a surgical procedure that improves blood flow to the heart. The surgery involves taking a healthy blood vessel from another part of the body—such as the chest wall, leg, or arm—and attaching it to the coronary artery above and below the narrowed area. This creates a new pathway for blood to flow to the heart muscle, bypassing the blockage[reference:2].

CABG is typically recommended for patients with:

  • Severe blockages in the left main coronary artery
  • Multiple blockages in two or three coronary arteries
  • Blockages that cannot be treated with angioplasty and stenting
  • Heart failure or severely reduced heart function
  • Diabetes with multiple vessel disease

In some cases, patients may have blockages that require bypass surgery as well as blockages that may be opened with stents[reference:3]. Read our guide on CAD angioplasty vs. CABG.

Learn more about coronary bypass surgery from Mayo Clinic.

3. Types of CABG Surgery

There are two main types of CABG operations currently available: on-pump and off-pump surgery[reference:4].

On-Pump CABG (Traditional Open-Heart Surgery)

On-pump procedures require the surgeon to open the chest bone (sternum), stop the patient’s heart, and place the patient on a heart-lung bypass machine[reference:5]. This machine takes over the function of the heart and lungs, allowing the surgeon to operate on a still, bloodless heart.

This is the most common type of CABG[reference:6]. During the surgery, the breast bone or sternum is cut open and split into two halves[reference:7]. The heart is stopped, and the surgeon performs the bypass using the heart-lung machine. Learn more about the heart-lung bypass machine in CABG.

Off-Pump CABG (Beating Heart Surgery)

Off-pump CABG is performed without the use of a heart-lung bypass machine[reference:8]. The heart continues to beat during the procedure, and the surgeon uses specialized equipment to stabilize the area of the heart being operated on[reference:9].

Off-pump CABG can be done as a minimally invasive direct coronary artery bypass (MIDCAB) procedure, where small incisions are made to insert surgical instruments and operate using a video feed[reference:10]. Minimally invasive techniques can reduce recovery time[reference:11].

Robotically Assisted CABG

Robotically assisted CABG is a minimally invasive alternative to traditional heart surgery[reference:12]. For this procedure, a small incision is made between the ribs (thoracotomy)[reference:13]. The surgeon uses robotic arms to perform the surgery with enhanced precision and control[reference:14]. This approach offers benefits such as faster recovery, less pain, and smaller scars[reference:15].

Minimally Invasive Direct Coronary Artery Bypass (MIDCAB)

MIDCAB is a type of off-pump CABG performed through small incisions between the ribs, without opening the entire chest. This approach is suitable for select patients with blockages in specific arteries[reference:16].

4. Types of Grafts Used in CABG

Several types of bypass grafts are used in CABG surgery. The type used depends on the size of the coronary arteries, the location and severity of the blockage, the patient’s age, and other health factors[reference:17]. The graft may be an artery or a vein. Arterial grafts are considered superior as these remain patent for a longer period[reference:18].

Internal Mammary Artery (IMA) / Left Internal Mammary Artery (LIMA)

The left internal mammary artery (LIMA) is often considered the gold standard for CABG. It is an artery located in the chest wall that is connected to the left anterior descending (LAD) artery. LIMA grafts have excellent long-term patency rates and are durable[reference:19]. Learn more about LIMA to LAD CABG.

Saphenous Vein Grafts

The saphenous vein, located in the leg, is the most commonly used vein graft. It is often used to bypass blockages in multiple arteries. While saphenous vein grafts are effective, they may develop blockages over time, typically within 10 years.

Radial Artery Grafts

The radial artery, located in the forearm, can also be used as a graft. It is more durable than saphenous vein grafts and is often used in younger patients or when multiple grafts are needed.

Right Internal Mammary Artery (RIMA)

The right internal mammary artery (RIMA) can be used in addition to the LIMA for patients requiring multiple bypasses. Bilateral internal mammary artery (BIMA) grafting can offer better long-term survival and lower risk of adverse cardiac events[reference:20].

5. The CABG Procedure Step-by-Step

Understanding exactly what happens during the procedure can remove much of the anxiety. In India’s top JCI-accredited hospitals, the workflow is seamless and patient-centric.

Step 1: Pre-Procedure Preparation

Blood tests, ECG, echocardiogram, and coronary angiogram are performed. You will be asked to fast for a few hours. The surgical team will review your medical history and prepare you for surgery.

Step 2: Anesthesia

General anesthesia is administered, and you will be asleep throughout the surgery. A breathing tube will be placed to assist with breathing during the procedure.

Step 3: Harvesting the Graft

The surgeon will remove a healthy blood vessel from another part of your body—typically the chest wall (internal mammary artery), leg (saphenous vein), or arm (radial artery).

Step 4: Opening the Chest

For traditional CABG, a vertical incision is made in the center of the chest, and the breastbone (sternum) is divided. This allows the surgeon to access the heart.

Step 5: Bypass Creation

In on-pump CABG, the heart is temporarily stopped, and a heart-lung bypass machine takes over circulation. The surgeon attaches one end of the graft to the coronary artery below the blockage and the other end to the aorta (or to another artery) above the blockage.

In off-pump CABG, the heart continues to beat, and the surgeon uses stabilization devices to hold the area of the heart being operated on[reference:21].

Step 6: Closing the Chest

After the bypass grafts are completed, the heart is restarted (if it was stopped), and the chest is closed with wires. The skin is closed with sutures or staples.

Step 7: Recovery and Monitoring

You will be moved to the cardiac intensive care unit (ICU) for close monitoring. Hospital care after bypass surgery typically lasts 4 to 7 days, starting with 2 to 3 days in the cardiac ICU followed by 3 to 4 days in the general ward before discharge[reference:22].

Learn more about heart bypass operation time.

6. CABG vs. Angioplasty and Stenting

Choosing between CABG and angioplasty with stenting depends on several factors, including the number of blocked vessels, the complexity of the disease, and the patient’s overall health. Read our guide on CAD angioplasty vs. CABG. Learn more about angioplasty and stenting.

Angioplasty and Stenting is a minimally invasive procedure where a small balloon is inflated to open the artery, and a stent is placed to keep it open. It is suitable for less complex blockages (1–2 vessels). The procedure is performed under local anesthesia, requires only 1–2 days of hospital stay, and recovery takes 1–2 weeks[reference:23].

CABG is an open-heart surgery best for complex disease (3+ vessels, left main). It is more invasive than stenting and requires a longer hospital stay and recovery period[reference:24]. However, it is especially effective for complex blockages and can provide longer-lasting results in certain patients[reference:25].

Bypass surgery remains the gold standard for complex, multi-vessel disease, especially in patients with diabetes[reference:26]. While stents offer a quick, minimally invasive recovery for simpler narrowings, CABG offers more durable results[reference:27]. Studies have shown CABG to be superior to PCI (angioplasty) in terms of mortality benefit for complex coronary artery disease[reference:28].

7. Recovery and Aftercare

Recovery from CABG is a gradual process that requires patience and commitment to following medical advice.

Immediate Recovery

After surgery, you will spend 2 to 3 days in the cardiac ICU, followed by 3 to 4 days in a general ward before discharge[reference:29]. During this time, you will be closely monitored for any complications.

Recovery at Home

Full recovery from CABG typically takes 6 to 12 weeks[reference:30]. During this time, you should:

  • Rest and avoid strenuous activities
  • Follow a heart-healthy diet
  • Take prescribed medications as directed
  • Attend cardiac rehabilitation sessions
  • Gradually increase physical activity

Cardiac Rehabilitation

Cardiac rehabilitation is a medically supervised program that helps patients recover from heart surgery. It includes exercise training, education on heart-healthy living, and counseling to reduce stress and improve mental health.

Long-Term Lifestyle Changes

To maintain heart health after CABG, patients are advised to:

  • Adopt a heart-healthy diet low in saturated fats and sodium
  • Engage in regular physical activity
  • Quit smoking
  • Manage stress
  • Take prescribed medications as directed
  • Attend regular follow-up appointments

Proper care and support are essential for a smooth recovery. Following medical guidelines is vital for long-term recovery[reference:31].

8. Benefits and Risks of CABG

Benefits of CABG

Coronary artery bypass grafting offers significant improvements in both survival and quality of life[reference:32]. The surgery can reduce a patient’s chest pain, difficulty breathing, and risk of heart disease-related death[reference:33]. It can offer patients a longer and better quality of life[reference:34].

Other benefits include:

  • Reduced chest pain (angina)
  • Improved heart function
  • Lower risk of heart attack
  • Increased ability to perform physical activities
  • Better overall quality of life

Multiarterial grafting can offer better long-term survival and lower risk of adverse cardiac events for patients undergoing CABG[reference:35].

Risks of CABG

Like any major surgery, CABG carries risks. Despite its benefits, CABG carries perioperative complications[reference:36]. Possible risks include[reference:37]:

  • Atrial fibrillation – An irregular heart rhythm[reference:38]
  • Acute kidney injury – Temporary kidney problems[reference:39]
  • Stroke[reference:40]
  • Surgical site infection – Infection at the chest wound site[reference:41]
  • Bleeding – Excessive bleeding during or after surgery[reference:42]
  • Heart attack – Due to a blood clot after surgery[reference:43]
  • Memory loss or cognitive issues

While early mortality rates are low, it is important to discuss potential risks with your surgical team[reference:44].

Long-term care involves medication, a healthy lifestyle, and cardiac rehabilitation[reference:45]. Long-term success depends on the patient’s health and lifestyle, as well as following the doctor’s advice after surgery[reference:46].

9. Cost of CABG in India
