Can healthy volunteers participate?
No
Key exclusion criteria
Patient:

- does not have autologous cord blood cells available at the time of cardiopulmonary
bypass surgery

- has evidence of arrhythmia requiring anti-arrhythmia therapy

- has an additional congenital diagnosis that contributes to conditions such as an
immune system disorder, immune deficiency, complex metabolic disorder, brain dysplasia
or progressive neurological degenerative disorder

- has other clinical complexity deemed by the cardiac surgeon to make the patient
unsuitable for inclusion in the trial
