Bypass SurgeryDr. Mangesh Danej
Before your surgery, you will get general anesthesia. You will be asleep (unconscious) and pain-free during surgery.Once you are unconscious, the heart surgeon will make an 8 to 10-inch (20.5 to 25.5 cm) surgical cut in the middle of your chest. Your breastbone will be separated to create an opening. This allows your surgeon to see your heart and aorta, the main blood vessel leading from the heart to the rest of your body.Most people who have coronary bypass surgery are connected to a heart-lung bypass machine, or bypass pump.
Your heart is stopped while you are connected to this machine.
This machine does the work of your heart and lungs while your heart is stopped for the surgery. The machine adds oxygen to your blood, moves blood through your body, and removes carbon dioxide.
Another type of bypass surgery does not use the heart-lung bypass machine. The procedure is done while your heart is still beating. This is called off-pump coronary artery bypass, or OPCAB.
