Bypass or bypass surgery (CABG) is a treatment for narrowing in the coronary arteries of the heart. Using an artery or vein from the patient's own body, the doctor makes a bypass along the narrowing. The bypass then allows sufficient blood to flow to the heart muscle again.

In the Divi bypass surgery, patients are shown in an animation how the bypass surgery is done. In addition, patients are given information in the Divi about the preparation, aftercare and risks of the procedure.
