Frequently Asked Questions
What is Bypass Surgery?
Bypass surgery of the heart involves the creation of a new route called a bypass. This procedure is also called Coronary artery bypass graft or CABG. This is performed due to the blockage of blood vessels of the heart. The blood vessels which supply blood to the heart are called Coronary arteries. One of these coronary arteries might get blocked and this condition is called Atherosclerosis or Coronary artery disease. The symptoms include chest pain, shortness of breath, etc. The bypass surgery helps in the easy flow of oxygen and blood to your heart. This procedure involves a healthy blood vessel taken from your arm or leg or chest and connecting it beyond the blocked arteries of the heart. This bypass heart surgery will not cure heart disease but it can save you from the symptoms of the blocked blood vessel.
There are different types of Bypass surgeries:
- Single bypass surgery (single artery is blocked)
- Double bypass surgery (two arteries are blocked)
- Triple bypass surgery (three arteries are blocked)
- Quadruple bypass surgery (four arteries are blocked)
What are the advantages of Bypass Surgery?
The advantages of Bypass surgery are as follows:
- It helps in reducing the symptoms of Coronary artery disease.
- Decreases the risk of recurrence of a heart attack.
What are the indications of Bypass Surgery?
The following are the indications of Bypass Surgery:
- Formation of plaque around the walls of arteries (Atherosclerosis)
- Blockage of arteries (Coronary artery disease)
- Less blood flow to the heart (Ischemia)
- Pain in the chest (Angina)
- Shortness of breath
What is the preparation for Bypass Surgery?
The following are the steps to prepare before the surgery:
- You may be asked about your present and past medical history and medication history.
- The doctor may ask you to undergo different lab tests before the surgery.
- Inform your doctor if you are using any blood thinners or pain killers.
- You may be having some imaging tests to see the condition of the blockages.
- You may be advised to stop eating or drinking before 6 hours of the procedure.
- Inform your doctor if you are allergic to anesthesia or to any known contrast dye.
- Discuss all the risks, complications, and benefits associated with the Bypass surgery with your doctor.
- You may be asked to sign the consent form before undergoing this procedure.
What are the steps involved in Bypass Surgery?
The following are the steps involved in Bypass surgery:
- General anesthesia will be given to avoid pain during the surgery.
- The next step involves making an incision in the middle of the chest by your surgeon.
- A cardiopulmonary bypass machine is connected to you. This machine is also called heart-lung surgery. It circulates oxygenated blood throughout the body while the surgical procedure is going on.
- A cooling technique is used by your surgeon to lower your body temperature. The amount of oxygen needed by your heart is very less when the body temperature is low. This technique helps in suspending the body's processes and making the heart surgery possible. It also helps in reducing the risk of heart or brain damage due to lack of oxygen.
- A healthy blood vessel from the chest wall or arm or leg is removed by the surgeon and placed near the blocked or damaged artery. This removed blood vessel is called graft.
- One end of the healthy blood vessel is attached over the blocked or damaged blood vessel while the other end is connected below it.
- After completion of this process, the surgeon will remove the heart-lung machine and the function of the bypass is monitored. Once the bypass starts functioning, the incision will be closed with the sutures and bandage and shifted to ICU.
What is the postprocedure care/recovery care for Bypass Surgery?
- After the completion of the procedure, you may need to stay in the hospital until you gain consciousness from the sedation.
- If there is a pain at the site of catheter insertion, then consult your doctor. If the pain is severe, use the pain killers as directed by the doctor.
- You may feel faint or weak, chest pain, and/or shortness of breath.
- If bleeding is seen at the incision site, consult your doctor as soon as possible.
- There should be follow-up visits to your doctor once in a while to monitor your condition.

- Admission fee
- Doctor fee
- Age of the patient
- Type of grafts used
- The medical condition of the patient
- Post-surgical complications that are involved
- Admission room that you opted for

Maximum cost in Delhi rises up to Rs. 4,50,000
Is Bypass Surgery a major surgery or minor surgery?
Bypass Surgery is considered major surgery. This surgery involves general anesthesia, an incision on the chest, and placement of the coronary artery graft.
What is the eligibility criteria for Bypass Surgery?
The eligibility criteria for Bypass surgery are as follows:
- Individuals who are at risk of developing heart disease.
- People who are suffering from angina.
- Individuals with severe chest pain during rest or stress.
- People suffering from severe atherosclerosis [the blockage of blood vessels]
What is the ineligibility criteria for Bypass Surgery?
The ineligibility criteria for Bypass surgery are as follows:
- Individuals suffering from severe kidney disease
- Patients who are currently on medications such as blood thinners and antiplatelets
- Patients allergic to anesthesia
What are the risks and complications associated with Bypass Surgery?
The following are the risks or complications involved in the Bypass Surgery:
- Irregular heartbeat
- Kidney problems
- Heart attack (sometimes the blood clot breaks after the surgery)
- Loss of memory or difficulty to make decisions (this may be improved within 6 to 12 months after the surgery)
How long does it take to complete Bypass Surgery?
The complete procedure of the Bypass surgery may take up to 3 to 6 hours.
What is the recovery time?
The recovery time for Bypass surgery may vary according to the:
- Patient's health condition
- Patient's age
However, the recovery time for bypass heart surgery is around 6 to 12 weeks.
What is the success rate of Bypass Surgery?
The success rate of Bypass surgery is 95%.
Is Bypass Surgery painful?
Every surgery comes with a certain level of pain and some discomfort. You won't be experiencing pain during this process because you will be under general anesthesia. There may be some discomfort after the procedure.

What are the long-term results of Bypass Surgery?
The following are the long-term results of Bypass Surgery:
- Medium to long-term survival is achieved
- Improvement in the symptoms of heart diseases
- Left ventricular ejection fraction is improved
Can Bypass Surgery be detected in the future?
Bypass surgery can be detected in the future with the help of screening or imaging tests.
What are the alternatives for Bypass Surgery?
