Blood troponins are used to diagnose perioperative myocardial injury and infarction. During liver transplantation, a passive donor-recipient troponin transfer with the graft may result in an increase of troponins in the transplant recipient questioning the diagnosis of myocardial injury. We present a case of liver transplantation with sudden elevation of recipient's serum troponin levels immediately after graft reperfusion and its subsequent normalization in which myocardial damage and other non-ischaemic potential causes were ruled out. Patient consent for publication was obtained prior to submission of the manuscript.
