The CABG is also called the heart bypass or the coronary artery bypass graft surgery. When the arteries of the heart are too narrow to supply adequate blood to the heart, a bypass around the narrow areas is performed, sometimes using a graft of vein or artery tissue. The average cost of this surgery is $40000. There are about 400000 of these surgeries every year.
The most common reason a CABG is done is for clogging of the coronary arteries. This may have been detected by a stress test, during a coronary catheter procedure (heart cath), or in the setting of chest pain or a heart attack.
