MICS CABG or Open CABG? Know the differences!

How does MICS CABG differ from open bypass?

MICS CABG is a bypass operation exactly like open bypass or CABG but without cutting the chest bone or sternum. 

Can all vessels be bypassed in MICS CABG?

Yes, all vessels can be bypassed in MICS CABG. This includes the right sided vessels as well. Its a common misconception spread by untrained and inexperienced surgeons that right side vessels cannot be bypassed. In fact the right sides vessels are the easiest to bypass in MICS CABG.

Is the durability of MICS CABG same as open surgery?

Yes, the durability of bypass grafts is the same as open CABG. The durability of any bypass operation open or MICS depends on the skill of the surgeon. In unskilled hands both operations can be dangerous. We have been performing MICS CABG for 12 years now and our results are excellent. 

Are some patients unsuitable for MICS CABG?

Some patients with very poor cardiac function from damage due to heart attack with poor quality vessels are unsuitable for MICS CABG. Also patients who are unstable with ongoing chest pain may be unsuitable. Patients who are very obese, especially if they are short as well may be unsuitable. The decision is best taken by your surgeon. With experience and expertise many patients who are considered unsuitable may also be candidates for MICS CABG

Open or traditional CABG?

An open CABG is the oldest technique of CABG or coronary artery bypass surgery and was first described in 1970. By cutting open the breast bone or sternum the acceess to the heart is the easiest. How ever this causes major injury to the chest wall and recovery is prolonged in most patients. Major chest wall injury results in pain, blood loss, infection and other complications that are higher. Some patients requiring a complicated operations such as a valve replacement with a CABG or aneursym surgery can only be performed by the traditoinal open technique.
