Donor #2 in Table 1. An example of a stress echocardiogram in a brain-dead potential donor, showing end-diastolic and end-systolic frames at rest and following stress using Dipyridamole (0.84 mg/kg in 6’) [see Additional file 1]. Left ventricular interventricular septum and apical wall a-kinesia are shown in parasternal long-axis (panel A) and short-axis (panel B) chamber views. At peak stress an incomplete viability response is shown. The donor was considered unsuitable for heart donation.
