What is Open Heart Surgery?

Open Heart Surgery is a type of surgery performed to treat heart problems. It involves opening the chest wall, including the breastbone, for the surgeon to access the heart. The surgery is performed on the heart’s muscles, arteries, or valves. Since this surgery has been performed for decades, it is also known as traditional heart surgery. 

Anatomy and Physiology of the Heart

The heart is a fist-size organ that pumps blood throughout the body. It is located at the centre of the chest, slightly pointing towards the left. It consists of the following parts:


The heart is divided into two upper (atria) and two lower (ventricles) chambers:

  1. Right atrium: It pumps deoxygenated blood to the right ventricle. 
  2. Right ventricle: Deoxygenated blood is carried by the pulmonary artery from the right ventricle to the lungs, where the blood is reloaded with oxygen.
  3. Left atrium: The oxygenated blood is carried from the lungs to the left atrium through pulmonary veins. The left atrium then delivers oxygenated blood to the left ventricle. 
  4. Left ventricle: It pumps oxygen-rich blood to the body. 


  1. Heart valves open and close to allow the flow of blood. 
  2. The atrioventricular valves open between the upper and lower heart chambers. 
  3. The semilunar valves open when blood flows out of the ventricles. 

Blood Vessels

The heart pumps blood through three blood vessels:

  1. Arteries (carry oxygenated blood from the heart to the body)
  2. Veins (carry deoxygenated blood to the heart)
  3. Capillaries (small blood vessels where the body exchanges oxygenated and deoxygenated blood)

Conditions Treated With Open Heart Surgery

A doctor may suggest open heart surgery to treat the following heart conditions:

  1. Arrhythmias (irregular heartbeat)
  2. Coronary artery disease (narrowing or blockage of the coronary arteries due to plaque buildup)
  3. Hereditary heart defects (such as underdeveloped heart structures or a hole in the heart)
  4. Heart valve disease (damaged or diseased valve in the heart)
  5. Heart failure (heart does not pump enough blood)
  6. Thoracic aortic aneurysm (a weakened area in the aorta wall)

Who Needs Open Heart Surgery?

An open heart surgery is ideal for patients who need the following:

  1. Repair or replace their heart valves
  2. Repair the damaged or abnormal heart areas
  3. Heart transplantation
  4. Medical device implantation for proper heartbeats

A person is an ideal candidate for open heart surgery if they:

  1. Are in a good physical condition
  2. Follow post-operative instructions
  3. Do not smoke

How is Open Heart Surgery performed?

Open heart surgery is a complex surgery that may take four hours or longer. The steps involved in the surgery may vary depending on the procedure. Some general steps for the surgery include:

Preparation for the Open Heart Surgery

  1. In the OT, the patient will lie in a supine position (lying horizontally on the back with the face pointing up) on the operating table. 
  2. The anesthesiologist will start an IV line in the patient’s arms or hands for fluids and medications. 
  3. They will administer general anaesthesia to make the patient sleep throughout the procedure. 
  4. The team will insert a breathing tube down the patient’s windpipe. 
  5. The nursing team will clean the surgical site with antimicrobial soap. 
  6. The anaesthesiologist will monitor the patient’s vitals, like heart rate, blood pressure, and breathing, throughout the procedure. 

The Final Surgery

  1. The surgeon will make a six- to eight-inch-long incision in the middle of the chest. 
  2. They will cut the patient’s breastbone and spread the ribcage apart to expose the heart. 
  3. Once the heart is visible, the surgeon will connect it to a heart-lung bypass machine in case of an on-pump surgery. The machine takes over the heart’s pumping action and diverts blood from the heart through tubes. 
  4. The anaesthesiologist will inject IV medication to stop the patient’s heart from beating, allowing the surgeon to operate. 
  5. The surgeon will restore blood flow to the heart and disconnect the heart-lung bypass machine. 
  6. The surgeon will close the breastbone with sutures and wires left inside the body. 
  7. Finally, the skin incision will be closed using stitches. 

Types of Open Heart Surgery

The various types of open heart surgery include:

  1. Coronary Artery Bypass Grafting (CABG): Also known as heart bypass or coronary bypass surgery, it is the most common open heart surgery performed today for patients suffering from coronary heart disease and atherosclerosis. In this procedure, the surgeon uses a healthy vein or artery from another body part and creates a new path around the blocked artery.
  2. Heart valve repair or replacement: To replace a damaged heart valve, the surgeon may replace the natural valve with an artificial one. For a valve repair, the procedure depends on the type of valve problem. For instance, the surgeon may insert a catheter into a blood vessel and inflate a balloon to reshape the valve and ensure better function. 
  3. Heart transplant: It is a surgery in which the surgeon replaces a failing heart with a healthier donor heart. The procedure is usually reserved for patients whose condition does not improve with medication and other surgeries. 
  4. Inserting an implantable cardioverter-defibrillator (ICD) or a pacemaker: ICDs and pacemakers are implanted in the patient’s chest to monitor and control irregular heartbeats. 

Please note: The procedure selection is based on the patient’s condition and the surgeon’s opinion.

What to expect Before and On the day of Open Heart Surgery

  1. It can save the lives of patients suffering from a heart attack or those at a high risk of having one. 
  2. It can help reduce discomfort caused by shortness of breath and ongoing angina due to diseased heart arteries. 
  3. After recovery from the surgery, patients will feel stronger, healthier, and ready to do things they love. 

Risks and Complications of Open Heart Surgery

Since open heart surgery is a major operation that even requires stopping the heart in several cases, it carries certain risks and complications. The common side effects of open heart surgery include:

  1. Allergic reaction to anaesthesia
  2. Bleeding
  3. Blood clots
  4. Infections in the incision or inside the chest (more common in patients with diabetes, obesity, and chronic kidney disease)
  5. Pneumonia

Complications specific to open heart surgery include:

  1. Heart attack or stroke
  2. Arrhythmia
  3. Lung or kidney failure
  4. Chest pain
  5. Memory loss
  6. Breathing difficulty

Sequelae of complications, if not treated in time, include:

  1. A heart attack, if not treated promptly, can cause permanent heart damage or even death. 

When to Consult a Doctor?

The patient should call the healthcare professional if they experience the following:

  1. A fever of more than 101℉
  2. Nausea and vomiting
  3. Chest pain

Frequently Asked Questions (FAQ)

  1. Myth: Open heart surgery is very risky. 
    Fact: With advancements in technology today, a well-planned open heart surgery like bypass surgery or valve replacement surgery carries very few risks. The open heart surgery success rate is more than 95% if performed at an appropriate time. 
  2. Myth: The surgery includes taking the heart out of the patient’s chest. 
    Fact: Not true! The heart is only stopped by connecting a heart-lung bypass machine to help perform the surgery. It is never taken out of the chest. Heart transplantation is the only procedure that involves the physical removal of the heart from the chest. 
  3. Myth: Open heart surgery is extremely painful. 
    Fact: The patient is given general anaesthesia to make them sleep throughout the procedure. Therefore, the patients will experience no pain during the surgery. Moreover, a painkiller can also help them manage pain and discomfort in the recovery phase after the surgery. 

An open heart surgery is an operation in which the chest is opened to perform surgery on the heart muscles, arteries, or valves. The procedure treats heart problems like arrhythmias, congenital heart defects, heart failure, and aneurysms. 

An open heart surgery is a major procedure that requires close monitoring of the patient and immediate post-operative care. The patient remains in an ICU for 1-3 days to receive further care.

In open heart surgery, the surgeon cuts the centre of the chest and spreads the rib cage to expose the heart. After opening the chest, the surgeon attaches a heart-lung machine to circulate blood and stops the heart temporarily. Once the problem is treated, the surgeon restores the functioning of the heart, removes the machines, and closes the incision. 


 Open heart surgery is a successful procedure that offers a new life to people. The one-year survival rates after open heart surgery are 96-97%. 

Yes, Coronary Artery Bypass Graft (CABG) is an open heart surgery used to treat coronary artery disease. The surgery is performed to divert blood around the clogged arteries, improving oxygen supply and blood flow to the heart.
An open heart surgery is a major operation that can take between three to six hours. In some situations, the procedure duration can even exceed six hours.

 Patients undergoing open heart surgery must stay in the hospital for about seven to ten days. During this duration, the doctor monitors the progress and checks for any signs of infection. 

 The seven to ten days hospital duration after an open heart surgery includes at least a day in the intensive care unit. Patients may remain in the ICU for 1-3 days, depending on their condition.

Open heart surgeries require opening the chest to access the heart. To reach the heart, surgeons cut through the breastbone and spread the ribs. 


 No. Since the procedure is performed under general anaesthesia, you will feel no pain during the surgery. 


After open heart surgery, the body takes several weeks to heal. You cannot go home alone after the surgery, as driving will be restricted for about four weeks. You may also need someone to stay with you until you resume your normal household activities. 


Yes, once the patient recovers, he/she can live a normal life and resume his/her normal activities. Open heart surgery is an effective way of giving people a new life. 


Open heart surgery is not at all painful because the surgery is performed under general anaesthesia. The patient will sleep throughout the process and not remember anything. 


Open heart surgery can be performed in two ways. In an on-pump surgery, the heart is temporarily stopped while you are connected to a heart-lung bypass machine. However, in an off-pump surgery, the heart keeps beating during the surgery. 

Anyone can experience the risks associated with open heart surgery. However, women, older people, and those with serious conditions like diabetes, obesity, and lung disease are at a high risk of complications.

 Yes, open heart surgery is a major procedure that involves opening the chest to reach the heart. The surgery is also performed to treat life-threatening conditions like heart attack and heart failure. Like all other surgeries, open heart surgery has some potential risks and complications. 


Yes, with technological advancements, heart valve replacement can now also be performed without open heart surgery. Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure for replacing damaged heart valves. The procedure is suitable for people with moderate to high risk of developing open heart surgery complications.
