For over 30 years, our feelings, thoughts, and actions have been determined by children with heart diseases. We research new and effective therapies at 20 German children's heart centers. We support clinics with modern medical equipment for paediatric cardiac care. Since 2001, we have been treating children from abroad in German clinics. Our volunteer mission teams operate on children in other countries, e.g. in Eritrea, El Salvador and Romania. Supported by more than 30,000 private individuals, many foundations as well as small and large companies, we finance our work only through donations.
