Benefits and Risks – Beating Heart Bypass Surgery

Beating heart bypass surgery or off pump coronary artery bypass (OPCAB) is a safe and proven option to conventional bypass surgery. Both Off Pump Coronary Artery Bypass (OPCAB) and traditional bypass surgery offer beneficial results.

Doing surgery on a beating heart eliminates the need for the heart-lung machine. This can result in fewer side effects.

Benefits

Some of the potential benefits of beating heart surgery include:

  • A lower risk of stroke1
  • Fewer problems with memory loss and thinking skills2,3,4
  • Lower death rate – especially among women and "high risk" patients5
  • Less need for transfusion6,7,8
  • Reduced injury to the heart9
  • Shorter hospital stay10
  • Fewer heart rhythm problems7

Long-term Success of OPCAB

The majority of OPCAB surgery patients have improvement or complete relief of their symptoms and remain symptom-free for several years.11 They may recover from surgery more quickly than those who go "on pump" and they may suffer from fewer post-operative complications.7

Risks

Coronary artery bypass surgery is one of the most common surgical procedures in the United States. Your risk of death from the surgery is usually very low. As with any surgery, there are risks involved. The risks are no greater for off-pump heart bypass surgery than for conventional bypass surgery. These risks can include but are not limited to:

  • Bleeding
  • Infection
  • Stroke
  • Kidney failure
  • Lung complications
  • Death

There are many factors that can determine your risk. Including:

  • Age (older than 70)
  • Your health at the time of the surgery
  • If you are having emergency surgery
  • Smoking
  • Poor heart muscle function
  • Diabetes
  • Chronic lung disease
  • Chronic kidney failure

Talk to Your Doctor

If you are facing cardiac surgery of any type, discuss these risk factors with your doctor to determine the best treatment for you.
