Strong left ventricular spots are more common in boys

Recently, it has been discovered that many mothers often have bright spots in the left atrium of their fetuses during B-ultrasound, which makes everyone feel uneasy. This indicator value has no clinical manifestation when taken independently and is very common among the yellow race. We need to combine other indicators, the first of which is Down syndrome. If it is done too early or in the middle stage of Down syndrome, it all depends on the risk value, and it should be doubled immediately. If it is still low risk, it is fine. If it is high risk, you can do amniocentesis. If the heart rate is normal, the heart structure and blood are good, there is no need to do a fetal heart ultrasound. Some people even think that strong spots in the left atrium are more common in boys. Is this correct?

The bright spot in the left atrium is more common in boys

The strong light spot in the left atrium has nothing to do with the gender of the fetus, and the gender of the fetus cannot usually be determined from symptoms. The gender of the fetus can only be determined through B-ultrasound. When a fetus has a bright spot on its heart, it is usually related to a sex chromosome disorder. It is recommended that you see a doctor to check the fetus's sex chromosome disorder. Patients are advised to pay attention to the effective combination of diet, eat more fruits and vegetables, reduce spicy food, avoid greasy food, and avoid smoking and drinking. Avoid seafood and other irritating foods, and participate in some outdoor activities appropriately.

Does the bright spot in the left atrium have any effect on the baby's development?

These strong light spots are usually caused by the thickening of the child's heart tissue during the decline process. There is no scientific evidence that this generally affects the child's heart function and health. Strong echo in the left atrium of the fetus is an ultrasound manifestation, not a heart malformation, nor an ultrasound diagnosis of fetal heart abnormalities. It is very common in clinical medicine, and the pathogenesis has not been established at this stage.

Single strong light spot in the left atrium is more common, and the possibility of haploid abnormality in the fetus is only 20%-1.8. The risk of haploid abnormalities in the right ventricle, multiple atria, or significant strong light exposure increases, and the fetus should undergo chromosome karyotype analysis if necessary. There is no established association between strong light exposure in the fetal heart chamber and congenital heart malformations and other non-chromosomal malformations. If only a bright spot is found in the fetus' heart without other positive findings, it should be recorded in the ultrasound report. At the same time, attention should be paid to whether there are other high-risk factors, such as the age of the pregnant woman. When the pregnant woman is ≥31 years old, the incidence of chromosomal abnormalities in the fetus with intentional bright spots is about 1/600.

The possibility of strong light spots being caused by chromosomal abnormalities is only 0.5%-1%. There is no problem with most strong light spots, and this has no practical significance in clinical medicine. However, it has also been found that this ultrasound hearing may appear in other intracardiac or extracardiac abnormalities, such as various congenital heart diseases, thickening of the nuchal translucency, cystic hygroma of the menstrual cavity, ventricular enlargement, cerebral herniation, strong echogenic intestinal tract, renal pelvic enlargement, abnormalities of fingers and toes, developmental delay, etc., as well as chromosomal abnormalities.
