Abstract
Early primary graft failure after pediatric orthotopic heart transplantation (OHT) has a high mortality rate and can occur due to several causes including but not limited to prolonged graft ischemia time, suboptimal preimplant myocardial preservation, hyperacute rejection, and maladaptation of the graft to the host's hemodynamic status. Mechanical circulatory support with either extracorporeal membrane oxygenation (ECMO) or ventricular assist device has been used for the rescue of primary graft failure in pediatric patients after heart transplant. Cardiac arrest before ECMO initiation in these patients is associated with adverse neurologic outcome although those surviving to hospital discharge generally have excellent long-term outcome. We report a case of early primary graft failure after OHT who required ECMO support and successful rescue with plasmapheresis, immunoglobulins, and alemtuzumab.
