Fetal left ventricle with strong light spot is a soft index abnormality in ultrasound examination, if there is no combination of other cardiac malformations or other soft index abnormalities, generally no clinical significance, and can be reviewed regularly, if there is a combination of cardiac structural abnormality or other soft index abnormality, it is necessary to carry out further chromosome examination. Fetal left ventricle with strong light spot is usually detected by fetal cardiac ultrasound, and most of the strong light spots are distributed near papillary muscles or tendon cords. If there is no combination of other cardiac anomalies or other soft index abnormalities, the possibility of fetal anomalies is small; if there is a combination of cardiac structural anomalies or other soft index abnormalities at the same time, then there is a high possibility of chromosomal abnormality in fetus, and chromosomal examination by amniocentesis is needed. If ultrasound reveals a strong light spot in the left ventricle of the fetus, consult an obstetrician, who will recommend regular review or further examination according to the situation.
