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.
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
Coronary artery bypass surgery is a very common surgical procedure. 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:
- Kidney failure
- Lung complications
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
- Poor heart muscle function
- 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.
