Traditional Bypass Surgery

Oklahoma Heart Institute is a leader in Coronary Artery Bypass Surgery (CABG). Often known simply as bypass surgery, this procedure is used to improve and, in some cases, restore blood flow to the heart muscle after a blockage has developed. Arteries from the chest and veins from the leg are used to bypass the blockages. While CABG is one of the most common procedures performed at Oklahoma Heart Institute, our surgical team approaches each case with uncommon expertise and care.


Minimally Invasive Heart Surgery

By Allen Cheng, MD

In minimally invasive heart surgery (MIS), also known as keyhole surgery, the surgeon performs heart surgery through small incisions without a sternotomy (splitting the breastbone). Rather, the surgeon operates through small incisions with specialized instruments and camera scopes, which will result in less pain and trauma and quicker recovery for many patients. This approach will also allow the surgeon to have a better view of certain parts of the heart, and therefore a better and more comprehensive operation. Numerous publications have been published and data has shown patients who underwent MIS procedures have a faster recovery time, shorter hospital stay, lower infection rate, less surgical pain and less blood loss. Surgeons use the smallest incision to provide the safest and most successful surgery. Currently, Dr. Allen Cheng is the only surgeon at Oklahoma Heart Institute who conducts MIS surgery (as of September 2017).
