Of the nine lungs that failed EVLP reconditioning, six displayed worsening pulmonary oedema and two showed signs of persistent hyperinflation and raised PVR, suggesting diffuse injury and a degree of intrinsic emphysema. This suggestion was later verified by a pathologist from pulmonary biopsies. Lastly, one set of lungs was turned down due to heavy microbial contamination with multiple gram-negative organisms identified in the tracheal aspirate.
