All you need to know about Coronary Artery Graft Bypass (CABG) Surgery

The cardiac department in Batra Hospital Delhi is one of the top centres for state-of-the-art heart

disease treatment. Our cardiology team has achieved great pioneering advancements in the

field of cardiological operations and treatments at an astounding pace and with an

the overwhelming success rate in the last few years


Coronary artery bypass graft surgery (CABG) is a surgical procedure to restore blood flow to the

areas of the heart where it is deficient. The surgery helps treat coronary artery disease, which

causes the blood vessels to narrow due to the build-up of atheroma (cholesterol) in the coronary

arteries. The narrowed blood vessels cannot properly supply oxygen-rich blood to the heart. The

coronary artery bypass graft surgery is done to bypass the blocked portion of the artery so that

the heart can receive oxygen-rich blood.

Who Are the Best Candidates for CABG surgery?

The doctor will decide whether the patient is a good candidate for the CABG surgery based on

different factors, including

  • • Severity of coronary artery disease
  • • Location of the blockage in the arteries
  • • How many blockages does the patient have?
  • • Patient's response to other treatments
  • • The severity of the blockage of coronary arteries

Who Should Not Consider CABG Surgery?

Patients are not considered good candidates if they have the following conditions

  • • Terminal illnesses like advanced cancer, liver failure
  • • Bleeding disorder
  • • Unable to tolerate anaesthesia

How to Prepare for CABG Surgery?

The cardiac surgeon will talk in-depth about coronary artery bypass graft surgery and its benefits and potential risks. The doctor will advise particular instructions that must be followed before the surgery. Moreover, the surgeon will also conduct several tests to maximise the safety & outcome of surgery. These may include electrocardiograms, echocardiograms, and stress tests. X-ray. CT scan angiography, and blood tests. There are specific ways to prepare for the CABG surgery, including:

  • • Stop taking blood-thinning medicines 3-5 days before the surgery
  • • Quit smoking
  • • Don't eat heavy food the night before the surgery
  • • Make arrangements to stay in the hospital for a few days (about 7-10)
  • • Take all medications prescribed by the doctor before surgery

How CABG surgery Is Done?

CABG is major surgery and is done as an in-patient hospitalization procedure. The surgery involves different steps.

First, the patient is taken to the surgery room, and the medical team inserts intravenous (IV) lines to infuse medications and fluid through one of the veins. Next, general anaesthesia is administered, and the team also puts the patient on intubation and ventilation. The surgeon then makes an incision at the centre of the chest and splits the breastbone down the middle to access the heart.

Then, the surgeon takes a healthy blood vessel from the arms or thighs and crafts the bypass. The upper end of the bypass is attached to the aorta, and the lower end of the bypass is attached to the blocked artery just past the blockage.

There are different techniques used for CABG surgery, including

Off-pump CABG: In this procedure, the surgeon does not stop the heart and performs the surgery with the heart still beating.

Minimally invasive CAB: In this procedure, the coronary bypass is crafted through small incisions in the chest, usually with the help of robotics and video imaging. The surgery is also known as keyhole surgery.

Possible Complications

Just like every other significant surgery, CABG surgery also runs the risk of developing certain complications, including:

  • • Bleeding from the incision site
  • • Infection
  • • Swelling around incision
  • • Arrhythmias
  • • Stroke

Taking Care of Yourself After Surgery

The patients are kept in the intensive care unit for one or two days. The healthcare team provides detailed information about cardiac rehabilitation through various education programmes and exercises. The team will ask the patient to perform strenuous activities for a few weeks, exercise regularly, follow a healthy lifestyle and diet, manage stress, and more.
