What does it mean to do a four-dimensional left ventricle with bright spots?

When doing four-dimensional color Doppler ultrasound, it is found that the fetus has a bright spot in the left ventricle, which refers to the plaque, focal or strip-like structure of the papillary muscle of the left ventricle of the fetus, and its echo intensity is similar to that of the surrounding bone structure. If the fetus at low risk shows a bright spot in the left ventricle alone without other abnormal ultrasound findings during pregnancy, it can be followed up during pregnancy without other invasive examinations. However, for high-risk fetuses, even if bright spots in the left ventricle are present alone and are not accompanied by other ultrasound abnormalities, the risk of chromosomal abnormalities will increase, and further examination based on clinical symptoms, medical history, etc. is needed. If a pregnant woman finds bright spots in the fetal left ventricle during four-dimensional color Doppler ultrasound during pregnancy, she should consult an obstetrician and decide whether to conduct further examinations based on her specific circumstances under the guidance of the doctor.
