Brief Summary
The investigators hypothesize that injecting donor bone marrow cells into the recipient thymus gland at the time of heart transplantation in children will prove to be feasible and safe. They further hypothesize that recipients receiving donor bone marrow will experience less acute rejection events with reduced long-term requirements for immunosuppressive medications when compared to controls who do not receive marrow but who are managed under an identical immunosuppressive protocol.

Outcome Measures
Primary Outcomes (1)
Determine if intra-thymic inoculation of donor bone marrow cells at time of heart transplantation in children will reduce frequency of acute rejection as well as long-term requirements of immunosuppressive medications when compared to control patients
Secondary Outcomes (1)
Compare results of serial in vitro immunological monitoring among patients receiving intra-thymic bone marrow and controls
