Successful Orthotopic Heart Transplantation With Positive Crossmatch in a Hyperimmunized Child on Mechanical Circulatory Support-Case Report.

In the pediatric population there is a shortage in the number of hearts available for transplantation. However, sometimes a heart transplant is urgently required to save lives. The problem arises when the patient is hyperimmunized and there is a positive crossmatch with the only available donor. We present such a case of a 9-year-old patient with dilated cardiomyopathy on ventricular assist device, in whom it was possible to perform a successful HT and also apply a successive prevention against graft rejection.
