Open heart surgery is the general term and coronary artery bypass grafting (or CABG) is a type of open heart surgery.

-Open heart surgery is like "opening the hood" of your car to do a repair.
-CABG is a type of repair you can do, after you "open the hood."
-Valve repair/replacement is another type of repair you can do after you "open the hood" or do an open heart surgery.

Other examples are doing surgeries on the aorta, fixing a hole in the heart, or even putting in a mechanical heart pump or a heart transplant.
These terms are used interchangeably. They are essentially the same. Open heart surgery could mean having a valve replaced as supposed to bypass surgery where the clogged arteries gets bypassed.
No difference. Same thing by different names.
