Please note this information may not necessarily reflect treatment at other hospitals.Most dating scans are done with a trans-abdominal transducer and a fullish bladder.For many people the results will show no abnormalities and no further heart scans will be needed.
However, if the fetal heart scan is carried out early, it will need to be repeated at around 20 weeks even if it is normal.
You do not need to prepare for the scan and you do not need a full bladder.
Usually, a fetal heart scan can take between five and 20 minutes depending on the factors outlined above. Ultrasound scans use only sound waves, rather than x-rays or magnetism, to form pictures.
The gel used on your abdomen may feel a bit cold but we will try to warm it up before we apply it.
We recognise that the hospital environment can prove to be demanding, worrying and intense and we aim to alleviate some of the stress to families by talking openly, listening to each other and working together in the best interests of the child.
This way we hope to create a partnership with families that is built on mutual respect and trust.
See our information sheet on Fetal heart scans: what happens next Please note this is a generic GOSH information sheet.
If you have specific questions about how this relates to your child, please ask your doctor.
At Great Ormond Street Hospital (GOSH) we use ultrasound to take pictures of the heart to see how it is developing and to look at the blood flow around it.
In most cases, it is to check that the heart is developing normally.
If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
