What we do

Helping children with heart conditions get the care they need

We work across the paediatric cardiac care journey, from identifying children who may need care to supporting treatment and strengthening the systems that make that care possible.

Who we are

Registered in Dodoma in 2019, working across Tanzania

The One New Heart Tanzania is committed to helping children with heart conditions access the care they need while strengthening the systems that make that care possible.

We are a non-governmental organisation registered on 11 March 2019, registration number 00NGO/R/5641. We do not run a hospital. We join the parts of the health system that already exist and fill the gaps between them.

Mission

To improve access to heart health services through prevention, early diagnosis, treatment support, awareness, advocacy, healthcare workforce development and sustainable partnerships.

Vision

A Tanzania where every child with a heart condition has a fair opportunity to receive timely and appropriate care.

01

Screening and early identification

Many children with heart conditions are not diagnosed early enough. We support community and clinical screening activities that help identify children who may need further cardiac assessment.

Referral and patient support

Diagnosis is only the beginning. We help connect families with appropriate hospitals and support them as they navigate the pathway towards specialist care.

Treatment and surgery

Working with hospitals and specialist teams, we help children who need surgery or a catheter procedure to get it, in Tanzania whenever possible.

Clinical training and capacity building

Sustainable cardiac care depends on skilled local teams. We support training, knowledge exchange and collaboration that strengthen clinical capacity.

Prevention and awareness

We support education and awareness activities that help communities understand heart conditions and prevention, including rheumatic heart disease.

Partnerships and systems strengthening
