Guide | Why Is Fetal Echocardiography Essential? Medical Experts Explain
A fetal echocardiogram is an ultrasound examination used to detect congenital heart disease (CHD). CHD is among the most common birth defects, affecting about 1% of newborns each year. The examination gives doctors important information for early diagnosis and for planning treatment that may be needed after birth.
How fetal echocardiography works
A fetal echocardiogram uses a probe called a transducer to emit sound waves. The waves pass through the pregnant woman's and fetus's tissues and return images of the fetal heart structures. The examination is painless and considered safe for both mother and baby. It usually takes 30 minutes to 2 hours, depending on the complexity of the fetal heart and the specific concern being evaluated.
Fetal echocardiography is similar to a routine prenatal ultrasound but focuses on the structure and function of the fetal heart.
Examination process
A sonographer performs the ultrasound, and a pediatric cardiologist analyzes and interprets the results. The examination is performed before birth to identify heart problems early, as about 25% of children with CHD need surgery or medication during their first year of life.
Preparing for the examination
Unlike some ultrasounds, fetal echocardiography does not require a full bladder; pregnant women may instead be advised to empty their bladder beforehand. The doctor may also request the following information:
The pregnant woman's cardiac history
Any family history of inherited heart disease
Relevant medical records
Specific concerns about fetal health
Why fetal echocardiography matters
Fetal echocardiography is primarily used to determine whether the fetal heart's structure and function are normal in the uterus. Congenital heart disease may involve septal defects or missing heart structures. Common types of CHD include:
Atrial septal defect
Truncus arteriosus
Tetralogy of Fallot
Double-outlet right ventricle
Pulmonary atresia
Hypoplastic left heart syndrome
Transposition of the great arteries and others
Early detection helps doctors plan postnatal care, including emergency surgery or medication.
Results and follow-up
A pediatric cardiologist explains the results to the parents and treating physician. Depending on gestational age, the diagnosis, and image quality, repeated examinations may be needed to assess severity. Even if the initial results are normal, the doctor may recommend further examinations during pregnancy.
Fetal echocardiography is more accurate after 17 weeks of pregnancy, although early screening can be performed by transvaginal ultrasound at 12 weeks. If a heart defect is detected, the doctor will explain possible treatment after birth and the prognosis.
CHD may also be associated with genetic conditions such as Down syndrome or DiGeorge syndrome. The doctor may recommend further testing, including high-resolution fetal ultrasound, fetal MRI, genetic counseling, or amniocentesis, for a comprehensive assessment of fetal health.
Safety of fetal echocardiography
Fetal echocardiography poses no significant risk to mother or baby. However, not completing a recommended examination may leave health risks unrecognized until after birth. Doctors therefore recommend the examination when indicated.
