Heart Bypass Surgery

When the arteries that carry blood to the heart become badly narrowed or blocked, the heart may not receive enough oxygen. This can lead to chest pain, breathing difficulty and, in serious cases, a heart attack. Heart bypass surgery is one of the treatments used when the blood flow needs to be restored around these blocked arteries.

What Is Heart Bypass Surgery?

Heart bypass surgery is also known as coronary artery bypass grafting or CABG. During the operation, the surgeon takes a healthy blood vessel from another part of the body and uses it to make a new route for blood.

The new vessel is joined to the coronary artery before and after the blocked area. Blood can then travel through this new route instead of passing through the narrowed section.

Depending on the number of blocked arteries, a person may need one bypass or several bypasses. This is why terms such as single, double, triple, or quadruple bypass are used.

Why Is Bypass Surgery Done?

A blocked coronary artery does not always mean that surgery is immediately required. Some patients can manage their condition with medicines, changes in diet and regular physical activity. Angioplasty and stenting may also be suitable in certain cases.

A doctor may recommend Heart bypass surgery when:

• Several heart arteries have major blockages.
• The blockage is in a difficult location.
• Chest pain continues even after treatment with medicines.
• Angioplasty is unlikely to give a good result.
• The patient has severe coronary artery disease along with other heart problems.

Before making a decision, the doctor will look at the patient’s medical history and test results.

How Is the Surgery Performed?

CABG is performed under general anaesthesia. In a conventional operation, the surgeon makes an opening in the chest to reach the heart. A healthy blood vessel is then prepared and connected to the coronary artery beyond the blockage.

The blood vessel used for the bypass may come from the chest, arm, or leg. In some operations, a heart-lung machine is used while the surgeon works on the heart. Certain patients may be suitable for off-pump or less invasive techniques.

The choice depends on the number and location of blockages, heart function and the patient’s overall health.

Recovery After Surgery

Recovery does not end when the patient leaves the hospital. The body needs time to heal, particularly around the chest incision. Patients are usually asked to avoid heavy lifting and strenuous activities during the early weeks.

Medicines should be taken exactly as advised. Follow-up visits allow the doctor to check healing and heart function. A cardiac rehabilitation programme can also help patients slowly return to normal activities.

It is equally important to work on the factors that contributed to coronary artery disease, such as smoking, unhealthy eating, high cholesterol, high blood pressure, or lack of physical activity.

Benefits of Heart Bypass Surgery

The main aim of Heart bypass surgery is to improve blood supply to the heart muscle. Many patients experience less chest pain and find that daily activities become easier after recovery.

For people with serious coronary artery disease, bypass surgery can also be an important part of reducing the risk of future heart complications. The expected benefit varies from one patient to another.

Heart Bypass Surgery in India

India has specialised cardiac hospitals where patients can access experienced cardiac surgeons, modern diagnostic equipment, intensive care facilities, and different surgical options. International patients can also arrange consultation and treatment through specialised medical care providers.

If Heart bypass surgery has been recommended, discussing the available options with a cardiologist and cardiac surgeon is important. They can review the artery blockages and suggest the treatment that fits the patient’s particular condition.
