Could a simple heart scan save mothers and babies?
NCT ID NCT04936815
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving pregnant women a heart ultrasound during routine check-ups can catch hidden heart problems and reduce risks like death, heart failure, or low baby health scores. About 9,000 women in Nepal will be randomly assigned to receive the ultrasound or standard care. Researchers will track outcomes for mothers and babies up to six weeks after birth.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transthoracic echocardiography (heart ultrasound)
- What this could lead to
- If it works, this could show that routine heart screening during pregnancy helps prevent serious complications like heart failure or death in mothers and newborns.
- What could go wrong
- This is a single-site trial in Nepal, so results may not apply everywhere. The screening might not reduce complications enough to be worth the cost or effort.
