Introduction
Especially during the second trimester of pregnancy, a 4D ultrasound examination can be performed—such as those offered by Grade A, Class 3 hospitals—so there’s no need to feel anxious. However, not all ultrasound machines are capable of performing 4D ultrasound examinations; there remains some variation in capability among different models.
Congenital heart disease (CHD) in the fetus can indeed be detected during pregnancy, and the timing of the examination is closely related to gestational age.
Can congenital heart disease be detected during pregnancy?
Especially during the second trimester, a four-dimensional (4D) ultrasound examination can be performed—such examinations are routinely available at tertiary Class-A hospitals. Therefore, there is no need for excessive anxiety. However, it should be noted that not all ultrasound machines possess equal sensitivity for detecting CHD; detection capability varies depending on equipment specifications and operator expertise. It is essential to maintain a relaxed mindset and actively optimize maternal health. In most cases, fetal CHD can be reliably identified through appropriate prenatal screening.
Current medical technology and imaging equipment are highly advanced and well-established, enabling effective prenatal detection of fetal CHD—particularly during the mid-gestation period, typically between 22 and 24 weeks’ gestation. A comprehensive 4D ultrasound examination conducted at this stage can often identify structural cardiac anomalies. For accurate diagnosis, however, the examination must be performed at a qualified medical facility equipped with appropriate technology and experienced personnel. Additional diagnostic methods—including fetal echocardiography and auscultation—may also be employed, as CHD is frequently associated with characteristic physical signs or structural abnormalities, including various forms of cardiac malformation.
Pregnant women must pay close attention to numerous aspects of their health and adopt comprehensive self-care measures. The development of CHD is influenced by multiple factors, including genetic predisposition and environmental exposures—such as poor sanitation, hazardous chemical agents, or ionizing radiation. Thus, pregnant women should strive for nutritional balance, avoid environments with high radiation exposure or significant physical or chemical pollution, and undergo regular antenatal check-ups to closely monitor both maternal health and fetal development.
