What is bypass surgery or coronary artery bypass grafting (CABG)?
It is an open heart surgery which is done to redirect the blood around a blocked artery in your heart, thereby improving the blood flow.
Why bypass surgery is done?
It is done when the arteries supplying blood to your heart are narrowed or blocked. It also lowers the risk of serious complications in people who are suffering from ischemic heart disease. In severe heart attacks, CABG may also be used as an emergency procedure.
How a bypass surgery is done?
The heart bypass surgery is done under general anaesthesia and drugs will be given to stop your heart, which helps the surgeon to operate on it while it's not beating. Medicines will be used to protect your heart function during the time that it's not beating. And you will be in the ventilator support that helps you in breathing during the procedure. The surgeon will take blood vessels from another part of the body and connect them to the blood vessels above and below the narrowed artery of your heart, bypassing the blocked coronary arteries. Depending on the severity and number of blockages, more than one blood vessel will be taken, mostly arteries from the arm or chest, or veins from the legs.
How long does the heart bypass surgery procedure last?
This type of surgery usually takes 3 to 5 hours to complete.
How long does it take for a patient to recover after the heart bypass surgery procedure?
You will be monitored in the intensive care unit (ICU) for one or two days after the surgery. During this time your heart rate, blood pressure, and oxygen levels will be checked regularly. Then you will be moved to your room and monitored for 3 to 5 days before going home. You should be able to sit after 1 day, walk after 3 days, and walk up and downstairs after 5 or 6 days. A full recovery is seen within 12 weeks of the operation in most of the people.
How much does it cost?
In India, a heart bypass surgery usually costs anywhere between INR 275,000 and INR 425,000. In some cases, it may cost more than that, depending on the hospital, surgeon and other medical factors.
