Strong echoes of the fetal heart on pregnancy testing are a common sonographic presentation on ultrasound, the vast majority of which have no clinical significance. The presence of cardiac echogenic spots may be associated with intraventricular thickening of the tendon cords to form echogenic spots, deposition of papillary minerals, early ischemic changes of the coronary artery endings within the papillary muscles, and incomplete perforation of the tendon cords of the papillary muscles (a variant of normal cardiac development). This phenomenon is most often seen in the left ventricle, but can also be seen in both the right and left ventricles, and less than 1% of the strongly echogenic light spots are caused by chromosomal abnormalities. In the case of intraventricular strong echogenic spots combined with other abnormalities, fetal structural malformations and chromosomal abnormalities should be excluded, and prenatal diagnosis or noninvasive DNA is required if necessary. When the ultrasound indicates strong echogenicity in the ventricle during the delivery test, the obstetrician can go to the obstetrics clinic and have a comprehensive evaluation by a professional doctor in combination with other indicators.
