What happens to the heart during pregnancy?

You might like to first read Your heart after childhood cancer [1].

During pregnancy and labour the heart needs to work much harder because it has to pump more blood around your body. Heart problems can sometimes develop when you're pregnant.

Make sure your maternity carers know what treatment you received - remember to give them a copy of your treatment summary ('health passport'), available from your LEAP team. Check the LEAP contacts at An introduction to long-term follow-up after childhood cancer [2].

Most young women do not have any problems but your healthcare team may need to check your heart during pregnancy.

Current recommendations about pregnancy and your heart after childhood cancer

Make sure your maternity carers have a copy of your treatment summary.

Echocardiogram

If you have had a heart scan (echocardiogram) before becoming pregnant and this was normal, you won't need further routine scans. If not, then you should have a heart scan during the first 3 months of pregnancy. If you develop shortness of breath, unexpected tiredness, blood pressure changes or ankle swelling, then you will need another heart scan. You will probably need to see the high-risk maternity team.

Specialised care

You may need specialist care - this might be from a medical doctor (obstetrician or GP). You will also be under the care of your midwife.

Your healthcare team may suggest a hospital birth rather than a home birth if they think you are high risk.
