Abstract Objective: To explore the clinical value of intrauterine strong echo point in prenatal diagnosis. Methods: A total of 1 442 pregnant women with singleton pregnancies who underwent prenatal ultrasonography from September 2015 to November 2016 were selected as subjects, and then the pregnant women with ultrasound examination of the fetal heart with strong echo point were classified as observation group, the same number of pregnant women with undetected strong echo point were selected as the control group. The detection rate, number, ventricular position and ultrasonic heart segment position of fetal heart echoes were observed. The age, NT value, body mass index, hemoglobin concentration, body mass index and abdominal subcutaneous fat thickness were compared between the two groups. Results: A total of 1 587 subjects were collected, of which 145 were excluded for incomplete data and 1 442 were included. There were 162 pregnant women detected fetal intrauterine strong echo, the detection rate was 11.23%. Of which 131 were left ventricular single or multiple strong echo points, the incidence was 80.9%; 9 were the right ventricular single or multiple strong echo point, the incidence was 5.6%; 22 were the left and right ventricle single or multiple strong echo point, the incidence of multiple strong echo points was 13.6%. There are 162 cases of pregnant women with intrauterine ventricular echo points found in the heart of the four-chamber view. The hemoglobin concentration, body mass index and abdominal subcutaneous fat thickness of the observation group were significantly lower than those of the control group(P<0.05). Conclusion: Fetal intraventricular strong echo point is a common ultrasound image of prenatal ultrasound, common in the left ventricle, mainly to a single strong light point, echo intensity close to or slightly stronger than the bones, more common in the heart of the four-chamber view. The formation of factors may be related to maternal hemoglobin concentration, body mass index, abdominal subcutaneous fat thickness and other factors.
