Extracorporeal circulation and cardiopulmonary bypass are synonymous terms denoting a method by which the blood that usually returns directly to the heart is temporarily drained from the superior and inferior venae cavae. The blood is diverted into a reservoir, where it is oxygenated and subsequently returned to the patient's arterial circulation. This process effectually excludes the heart from the general circulation and leaves it empty so that it can accommodate surgical intervention (Fig. 1).
