Punctate echoes in the left ventricle of the fetus may be the result of calcification foci in the papillary muscles of the fetal heart, or a combination of chromosomal abnormalities in the fetus. Fetal left ventricle punctate echoes found by ultrasound during pregnancy test should be combined with other ultrasound indicators to determine whether it is physiological or pathological. Fetal left ventricular punctate echoes, not combined with other structural anomalies, are calcified foci in the papillary muscles of the fetal heart, which is physiological and will disappear gradually with the increase of gestational weeks, will not increase the risk of chromosomal abnormality, and will not affect the development and function of the fetal heart. The risk of chromosomal abnormality is higher when fetal left ventricle has punctate echoes and cardiac abnormality, such as in some fetuses with trisomy 21, which also have punctate echoes on ultrasound, and should be further examined by non-invasive DNA or amniocentesis. Fetal left ventricle see punctate strong echo is recommended under the guidance of professional obstetricians and gynecologists for genetic counseling, abnormalities in time to deal with.
