This is a complex procedure to treat coronary artery disease, wherein the major blood vessels supplying oxygen-rich blood to the heart get blocked by deposits containing fat and other materials (plaque).
In a CABG procedure, the blocked part of the coronary artery is replaced with a section of a healthy vein or artery taken from another part of the body and it is called a graft.
The surgeon attaches one end of the graft to an area of the heart above the blockage in the artery, while the other end is attached to an area of the coronary artery below the blockage.
So, blood flow to the heart is diverted and thus restored.
At HMH, cardiac surgeons are well-versed in performing the ‘off-pump’ CABG.  Also called the ‘beating heart’ surgery, in this highly advanced procedure the surgeon operates on the heart as it is beating, without stopping and connecting it to a heart lung machine as is conventionally done in many cardiac operations.
This is particularly helpful in high-risk patients,
who may have other lifestyle disorders such as high blood pressure, diabetes and so on.
