Coronary Artery Bypass (On Beating Heart)

When patients’ arteries cannot supply enough blood and oxygen to the heart, the doctor may recommend you undergo a coronary artery bypass graft surgery. CABG surgery restores blood flow to the heart so that the heart muscle can maintain a good blood supply. Beating heart by-pass surgery simply is bypass surgery that is performed on the heart while it is beating. Patients’ heart will not be stopped during surgery and this surgery doesn’t require a heart-lung machine. There are some risks associated with stopping the heart and replacing its functions with the heart lung machine. During beating heart by-pass surgery patients’ heart and lungs will continue working and this reduces risks of potential bleeding or a major stroke.

Coronary Artery Bypass (On Beating Heart)


Both off pump and conventional on pump surgeries restore blood flow to the heart but off pump bypass surgery has proven to reduce side effects for certain types of patients.

How is it performed?

  1. The doctor will take a healthy blood vessel from the patient’s chest, arm or leg. This is called a graft.
  2. The surgeon attaches one end of health vein to an area of the heart above the blockage in the artery. The other end is attached to an area of the coronary artery below where it is clogged.
  3. What is challenging on the beating heart bypass surgery is that, it is difficult to sew on a beating heart. The surgeon uses a stabilization device to keep the heart steady and which makes possible working on it.

What Happens After My Off-Pump Bypass Surgery?

  • Patients will complete their recovery time much earlier than patients who undergo a conventional by-pass surgery. Recovery time has been reported to be as short as 3-4 weeks. Since the patients are not placed on the heart lung machine, they experience quicker recoveries.

  • Hospitalization time is generally shorter when compared to the traditional by pass. (approximatively 1 week)

  • Risk of a stroke and the need for blood transfusions are reduced.
