Abstract

Objective: Exploring the application value of four-dimensional ultrasound spatiotemporal image correlation (STIC) technology in prenatal diagnosis of congenital heart disease (CHD) in mid-pregnancy fetuses.

Method: 11456 pregnant women who underwent fetal heart malformation screening from January 2021 to December 2022 at our hospital were selected as the study subjects. All pregnant women underwent two-dimensional ultrasound and four-dimensional ultrasound STIC technology examination. Follow-up was conducted to confirm the fetal heart condition through live birth or pathological results of induced abortion. The follow-up results were used as the 'gold standard' to compare and analyze the application time of two-dimensional ultrasound and four-dimensional ultrasound STIC technology in CHD examination, as well as the image acquisition time, display of standard cardiac sections, and accuracy, sensitivity, and specificity.

Results: In this study, 200 cases of CHD were confirmed through live birth or pathological results of induced abortion. In the diagnostic examination of these 200 cases of CHD, four-dimensional ultrasound STIC technology had shorter examination and image acquisition time than two-dimensional ultrasound. It also demonstrated higher accuracy, sensitivity, and specificity compared to two-dimensional ultrasound, with lower rates of missed diagnosis and misdiagnosis. Four-dimensional ultrasound STIC technology showed higher overall satisfaction rates than two-dimensional ultrasound in displaying the right ventricular outflow tract, five-chamber heart plane, left ventricular outflow tract, aortic arch plane, three-vessel trachea plane, caval vein long-axis plane, ductal arch plane, and four-chamber heart plane.

Conclusion: In the diagnostic examination of CHD, the use of four-dimensional ultrasound STIC technology can reduce the examination time for pregnant women. It provides a more comprehensive display of various standard cardiac the fetal heart, which can improve the accuracy, sensitivity, and specificity of the diagnosis. Additionally, it can reduce the rates of missed diagnosis and misdiagnosis.
