- 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.

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.
