Primary graft dysfunction (PGD) is a frequent complication after heart transplantation (HT) and remains among the leading causes of mortality in these patients. We aim to identify factors implicated in the development of PGD, thus shedding light on possible preventive strategies.
Methods:Retrospective review of 99 patients who underwent HT between 2012 and 2015. 18 patients developed PGD. Donor and surgical procedure characteristics were studied in PGD patients and compared with patients without PGD.

Results:In univariate analysis, opioid use (p=0.049), death due to anoxia (p=0.021) and receptor/donor blood type match AB/A were associated with PGD (p=0.031). Time from brain death to aortic cross clamp (TBDACC) ≥3 days was found protective from PGD development (p=0.0011). Multivariate analysis confirmed patients with a TBDACC ≥3 days had lower odds of developing PGD [OR=0.098 (95%CI=0.021-0.443), p=0.0026].
We found that a TBDACC ≥3 days was a significant protective factor for PGD. Prior studies suggest brain death triggers a catecholamine surge that increases the myocardiocytes susceptibility to injury. We hypothesize that if longer time elapses after brain death, adaptive tissue mechanisms take place to blunt this pathologic response, thus decreasing the likelihood of PGD.
