Impact of donor blood type on outcomes after prolonged allograft ischemic times.
The study objective was to determine the influence of allograft ischemic time on heart transplant outcomes among ABO donor organ types given limited prior reports of its survival impact. ⋯ Compared with non-O donor hearts, transplantation with O donor hearts with ischemic time 4 hours or more leads to worse survival, with higher rates of primary graft dysfunction and chronic rejection. Caution should be practiced when considering donor hearts with the O blood type when anticipating extended cold ischemic times.

Pattern, behavior, and clinical implications of electrocardiographic changes in patients undergoing repair of anomalous aortic origin of coronary arteries.
Surgical repair in anomalous aortic origin of a coronary artery aims at mitigating the risk of sudden cardiac death in a subset of patients. The pattern and behavior of electrocardiogram changes in a large cohort of these patients are lacking. We aim to describe postoperative electrocardiogram changes in this population and its clinical implications on follow-up. ⋯ ST-segment changes and T-wave abnormalities are commonly seen in the postoperative period after anomalous aortic origin of a coronary artery repair, tend to resolve over time, and are not associated with adverse medium-term outcomes. Pathologic Q waves were associated with the need for early coronary reintervention.
