Helping children with heart conditions get the care they need

The One New Heart Tanzania works to improve access to paediatric cardiac care in Tanzania by helping children and families reach diagnosis, treatment and follow-up while strengthening the systems that make this care possible.

Skills that stay in Tanzania

Every mission is also a classroom. Tanzanian doctors, nurses and technicians train alongside visiting specialists, so the skills stay here.

The problem

Heart disease in children can be missed. Early detection matters.

babies is born with a congenital heart defect.

2.1%

of school children in a Tanzanian screening study had subclinical rheumatic heart disease.

Limited access

to cardiac diagnostic services makes early detection difficult, especially outside major centres.
