Research status of machine perfusion of heart / 器官移植

ABSTRACT

High-quality donor heart is the prerequisite and fundamental guarantee for successful heart transplantation. Reasonable donor heart preservation technique plays a key role in improving the quality of donor heart and the prognosis of heart transplantation. Static cold storage (SCS) is currently the standard preservation technique for cardiac allograft. However, it is prone to cause severe cold ischemia injury to the donor heart, and it is impossible to evaluate heart function during SCS. As an important emerging technique of organ preservation, machine perfusion better matches with physiological conditions compared with SCS, which may remove metabolic wastes and provide basic substances for metabolic needs during organ preservation, prolong the preservation time and improve the preservation effect to a certain extent. Besides, it may also effectively evaluate organ function and improve clinical prognosis of heart transplantation. Meantime, it can also repair organ damage, significantly optimize organ quality and improve the utilization rate of donor organs. In this article, research status of machine perfusion of donor heart was reviewed.
