Extracorporeal circulation: "Coronary artery bypass grafting (CABG) remains one of the most common and, arguably, the most important operation that cardiac surgeons perform.

Szeto emphasize (in their contribution to ´Extracorporeal circulation in theory and practice´, edited by Rudolf Tschaut et al.).
