EIF is a bright 1 – 6 mm spot seen in the fetal ventricle on ultrasound. The detection rate of EIF reported in the literature varies widely, ranging from 0.17% to 20%, which may be related to the difference in the composition of the population selected for different studies, the gestational week, the fetal position and the resolution of the instruments used. In my own experience, the chance of detecting ventricular spots is very high between 22 and 24 weeks of gestation, and most of the spots can be seen in the fetal ventricle during this time period; after 32 weeks, the detection rate of ventricular spots decreases; by 36 weeks, they are basically rare. So, what exactly is a ventricular spot? Our heart is made up of several chambers, one atrium and one ventricle on each side, and a door separating them. What controls the opening and closing of these two doors are some chains, which are attached to the wall at one end and to the door at the other. If these chains are thickened or increased, or if the chains and doors are not clearly separated because the fetal heart is too small, then strong light spots will be seen on the ultrasound. I think one of the reasons for the panic among mothers-to-be may lie in (Down syndrome). Early studies showed that in fetuses with chromosomal abnormalities such as (Down’s syndrome), the chances of ultrasound detecting strong light spots in the ventricles were significantly higher. Later, however, studies in large samples of average, low-risk pregnant women found that in the absence of other indicators of chromosomal abnormalities – such as widening of the lateral ventricles, posterior cranial fossa effusion, strong echogenicity of the intestinal canal, separation of the renal collecting system, etc. – strong fetal ventricular spotting is an obstetric ultrasound This is a normal variation of the obstetric ultrasound examination. In other words, if the result of Down screening is (low risk) and there are no other abnormalities, the mother-to-be does not need to worry about (ventricular spots)! If you can’t, think of it as a pimple on your face, which will always fade away. However, if the Down screening result is (high risk), then further tests (such as amniocentesis) are needed to rule out chromosomal abnormalities, regardless of whether they are combined with other parts of the abnormality. Many mothers-to-be rush to have a fetal heart ultrasound after having a (3D) or (4D) ultrasound and finding a strong ventricular spot. Is it necessary to have a fetal heart ultrasound? Actually, those who are qualified to perform (3D) or (4D) ultrasound are senior doctors with rich clinical experience. Unless (3D) or (4D) ultrasound indicates (abnormal fetal heart structure), it is better to choose whether or not to do further non-invasive DNA or amniocentesis based on the results of Down screening, instead of having another fetal echocardiogram, if only because of ventricular hyperopia. Therefore, fetal ventricular macularity may not be associated with any cardiovascular abnormality and does not cause any cardiac hemodynamic changes, but rather is a simple, transient, normal variant.
