Abstract: The invention provides, in various embodiments, a method comprising placing an ex-vivo heart in a chamber of an organ care system; connecting the ex-vivo heart to a perfusion fluid circuit of the organ care system; starting a pump configured to provide, via the perfusion fluid circuit, a perfusion fluid to the ex-vivo heart; synchronizing at least one maximum output of the pump with an r-wave of the ex-vivo heart; testing the ex-vivo heart or the organ care system; adjusting a setting of the organ care system in response to a result of the testing; and after adjusting the setting of the organ care system in response to the result of the testing, re-testing the ex-vivo heart or the organ care system.

Abstract: The disclosure provides, in various embodiments, systems, devices and methods relating to ex-vivo organ care. In certain embodiments, the disclosure relates to maintaining an organ ex-vivo at near-physiologic conditions. The present application describes, for example, a method for using lactate measurement in the arterial and the venous blood lines of the Organ Care System Heart perfusion device to evaluate, for example, the: 1) overall perfusion status of an isolated heart; 2) metabolic status of an isolated heart; and 3) overall vascular patency of an isolated donor heart. This aspect of the present disclosure may use, for example, the property of myocardial cell's unique ability to produce/generate lactate when they are starved for oxygen and metabolize/utilize lactate for energy production when they are well perfused with oxygen.
