Is it necessary to have an echocardiogram if the four-dimensional ultrasound shows no abnormalities?

Even if the four-dimensional ultrasound shows no abnormalities, it is still recommended to undergo fetal echocardiography according to prenatal care guidelines. These two examinations focus on different aspects: the four-dimensional ultrasound emphasizes overall structural screening of the fetus, while echocardiography specializes in detailed evaluation of cardiac structure and function, enabling detection of heart problems that may be missed by four-dimensional ultrasound. If there are high-risk factors or abnormal findings during pregnancy, timely medical consultation and further assessment are advised.

The four-dimensional ultrasound primarily screens for major structural malformations in important fetal organs. Its assessment of the heart is general and routine, making it difficult to thoroughly evaluate fine details such as cardiac valves, blood vessels, and hemodynamics.

Fetal echocardiography is a specialized examination focusing specifically on the fetal heart. It clearly visualizes chamber size, myocardial thickness, valve movement, and blood flow patency, allowing accurate detection of congenital heart diseases. This test is especially essential for pregnant women with high-risk factors such as a family history of heart disease or infections during pregnancy.

It is important to complete all scheduled prenatal checkups on time to avoid missing specialized screenings; maintain regular作息 and a light diet, avoiding tobacco, alcohol, and harmful substances; stay emotionally balanced, engage in moderate walking, and create favorable conditions for healthy fetal development.
