Your 20-week pregnancy scan. Think 20.

The 20 week scan – the fetal anomaly screening that all mums-to-be are offered by the NHS – is the best chance to detect heart defects before the baby is born. But at the moment, only just over half of these life-threatening defects are spotted during pregnancy – and we’re trying to help sonographers and increase that.

Think 20 Tiny Tickers

Spotting these defects early is important. Research shows it leads to better survival rates and quality of life. And detection during pregnancy means the necessary preparations can be made: the right medical experts can be on hand at birth; treatment can begin as early as possible; and parents-to-be can receive specialist support.

Think 20. Think HEART. is an awareness raising campaign to give every baby’s heart the best possible start.

We want to reach as many pregnant women and new mums as possible, and give them the information they need to protect their ‘tiny ticker’ from the 20-week pregnancy scan and beyond!

Do you know what to expect from your 20-week scan?

Test your knowledge

In the vast majority of cases, your sonographer will be able to give you the reassurance that your baby’s heart has been thoroughly checked and all looks healthy. If your sonographer does think your baby may have a poorly heart, helping spot it at your scan means you’ll start receiving the care and support you and your baby need from the earliest opportunity.

You’ll know you helped give your baby’s heart the best possible start.


‘Knowledge is power. If we hadn’t known about Finn’s heart condition we may not have been so lucky. And that’s exactly what we are – incredibly lucky.’ – Jess, Finn’s mum
