You may qualify if:

  • Registered primary liver transplant candidate, male or female
  • Age ≥ 18 years
  • Signed (1) written informed consent document and (2) authorization to use and disclose protected health information

You may not qualify if:

  • Acute, fulminant liver failure
  • Prior solid organ or bone marrow transplant
  • Chronic use of hemodialysis or diagnosis of chronic renal failure, defined as chronic serum creatinine of \> 3 mg/dl for \> 2 weeks and/or requiring hemodialysis
  • Multi-organ transplant
  • Ventilator dependent
  • Dependent on \> 1 IV inotrope to maintain hemodynamics
  • Donor age ≥ 40 years, or
  • Expected cross-clamp time ≥ 6 hours, or
  • Donor after circulatory death (DCD) with age ≤ 55 years, or
  • Steatotic liver \> 0% and ≤ 40% macrosteatosis at time of retrieval
  • Living donors
  • Liver intended for split transplants
  • Positive serology (HIV, Hepatitis B surface antigen \& Hepatitis C)
  • Presence of moderate or severe traumatic liver injury, or anatomical liver abnormalities that would compromise ex-vivo perfusion of the donor liver (i.e., accessory blood vessels or other anatomy that require surgical repair) and livers with active bleeding (e.g., hematomas)
  • Donor livers with macrosteatosis of \> 40% based on retrieval biopsy readout.
