Mehmet Oz, MD, Cardiology, answeredWhen surgery is performed “off-pump,” it means the heart is not stopped and a heart-lung machine does not take over the functions of the heart and lungs during the procedure. Learn more about this procedure by watching this animation.
Intermountain Healthcare answeredOff pump means without the use of a heart-lung bypass machine. Open heart surgeries performed on beating (not stopped) hearts are called "off-pump" surgeries -- they don't require the use of a heart-lung bypass machine.

In many cases, coronary artery bypass grafting can be performed without the use of the heart-lung machine. In this "off-pump" (also called beating heart) technique, a small vertical incision is made in the chest, and a mechanical stabilizing device is used to restrict movement of the heart so that the surgeon can perform surgery while the heart is beating. Patients may be given a drug to slow the heart rate, but the heart maintains its own rhythm without the assistance of the heart-lung machine. The potential benefits of off-pump surgery include a shorter hospital stay and recovery time, less bleeding, less potential for infection, and less trauma.
