Identify structural and functional heart defects
Fetal echocardiography can diagnose a wide range of conditions – from simple septal defects to complex anomalies like hypoplastic left heart syndrome or transposition of the great arteries.
Fetal echocardiography is a specialised ultrasound examination that focuses exclusively on the fetal heart. It uses high‑frequency transducers, advanced imaging techniques, and Doppler to visualise the heart's anatomy, rhythm, and function in exquisite detail – far beyond what is possible with a standard anomaly scan.
This targeted examination is typically performed between 18 and 24 weeks, although it can be done earlier or later depending on the indication. It evaluates the four chambers, the outflow tracts, the great vessels, and the heart's connections – looking for congenital heart defects (CHDs), which are among the most common birth defects. Early detection allows for planning of delivery, neonatal care, and potential interventions.
At Amytri, our fetal echocardiography is performed by a consultant radiologist with advanced training in fetal cardiology. Using state‑of‑the‑art ultrasound equipment, we systematically assess every cardiac structure, often with colour and spectral Doppler. We provide a detailed report and, if any abnormality is detected, we discuss the implications, offer genetic counseling, and coordinate with paediatric cardiology teams – ensuring comprehensive, multidisciplinary care.
Congenital heart defects are among the most common birth anomalies. Detecting them prenatally allows for optimal planning, improved outcomes, and better long‑term prognosis.
Fetal echocardiography can diagnose a wide range of conditions – from simple septal defects to complex anomalies like hypoplastic left heart syndrome or transposition of the great arteries.
If a heart defect is identified, we can coordinate delivery at a centre with paediatric cardiology and cardiac surgery expertise, ensuring your baby receives immediate specialist care.
For most babies, fetal echocardiography confirms a structurally normal heart – providing profound reassurance, especially if you had risk factors or a previous concern.
Our fetal echocardiography follows a strict protocol, examining the heart from multiple planes and using specialised modalities to capture every detail.
We assess the size, symmetry, and septal integrity of the two atria and two ventricles – the foundation of any cardiac evaluation.
We evaluate the left and right ventricular outflow tracts, the aorta and pulmonary artery, and their spatial relationship – essential for detecting transposition, tetralogy of Fallot, and other anomalies.
We visualise the aortic arch and ductus to rule out coarctation, interrupted aortic arch, and other arch anomalies.
We use colour and spectral Doppler to assess blood flow across valves, in the great vessels, and through the ductus – evaluating for stenosis, regurgitation, or abnormal shunting.
We monitor the fetal heart rate and look for arrhythmias – including tachycardia, bradycardia, and irregular rhythms – using M‑mode or tissue Doppler.
We check for pericardial effusion and evaluate the position of the heart within the chest – abnormal position may indicate diaphragmatic hernia or other conditions.
Your obstetrician or fetal medicine specialist refers you. We collect all relevant medical records and scan images to prepare for the examination.
We perform a comprehensive ultrasound of the fetal heart, using multiple planes and Doppler. The scan takes 30‑45 minutes and is painless.
We review the findings in real time. If the heart is normal, we provide reassurance. If an anomaly is detected, we discuss its nature, implications, and next steps.
We coordinate with paediatric cardiology, neonatology, and other specialists to plan delivery and postnatal care – ensuring your baby receives the best possible support.
While it is not a routine scan for all pregnancies, it is strongly advised for those with elevated risk factors.
If you or your partner have a congenital heart defect, or if a previous child had one, the risk increases significantly – fetal echocardiography is recommended.
If the 20‑week scan shows an abnormal four‑chamber view or outflow tract, a targeted echocardiography provides the definitive assessment.
Maternal diabetes, especially poorly controlled, and other conditions increase the risk of fetal heart defects – echocardiography is advised.
Certain chromosomal anomalies (Trisomy 21, 18, 13) and syndromes (e.g., Noonan, DiGeorge) are often associated with heart defects – echocardiography is recommended.
If an irregular heart rhythm is detected, echocardiography can assess for structural causes and guide management.
Some medications (e.g., lithium, antiepileptics) or infections (e.g., rubella) increase the risk of congenital heart defects – echocardiography can provide reassurance.
Fetal echocardiography requires advanced training and a deep understanding of fetal cardiac anatomy and haemodynamics. Our consultant radiologist has extensive experience in this field and works closely with paediatric cardiologists to ensure the most accurate diagnosis and optimal planning for your baby.
Fetal echocardiography can be an emotional experience – having your partner present provides support and shared understanding.
We encourage partners to attend. We show you the heart's structures on screen, explain each part, and answer your questions. If any concerns arise, we discuss them sensitively and provide a clear plan for further care.
It is a specialised ultrasound of the fetal heart, performed by a trained specialist, to evaluate the heart's structure, function, rhythm, and blood flow. It is the most detailed assessment of the fetal heart available.
The ideal timing is between 18 and 24 weeks, when the heart is large enough to visualise in detail. However, it can be performed earlier or later if clinically indicated.
Yes. It uses standard diagnostic ultrasound, which has no known harmful effects on the mother or baby. It does not involve radiation.
We will discuss the findings with you in detail. We will refer you to a paediatric cardiologist and coordinate delivery at a centre with appropriate neonatal and cardiac surgical expertise. Many heart defects can be treated successfully after birth.
A referral from your obstetrician or fetal medicine specialist is typically required. We will work closely with them to ensure continuity of care.
Approximately 30‑45 minutes. Sometimes it may take longer if the baby is not in a good position or if we need to repeat views for accuracy.
