The project focuses on children with inborn heart defects, which in many cases cannot receive medical treatment within the country at this time. Children with inborn defects are commonly found on the edge of the society in economical or cultural sense; their lives sometimes end up terminal or they live their lives with heart defects leading to severe disability. The focus of this project is to help and organize the capacities to create the first children cardiac center in eastern Africa. Our project activity indicators are the number of local medical staff receiving the training, skills and knowledge transfer, as well as the number of complex medical cases being diagnosed, operated or closed.
