【Objective】To  compare  the  application  value  of  electronic  spatiotemporal  image  correlation （eSTIC） technology and conventional spatiotemporal image correlation （STIC） technology in displaying fetal heart structure.【Methods】A total of 180 pregnant women who underwent prenatal fetal cardiac ultrasound in our hospital from January 2018 to December 2019 were randomly selected. A trained sonographer used STIC and eSTIC technology to obtain and store volume data of the enrolled fetal hearts，respectively. Another two experienced sonographer performed an offline analysis of the obtained volume data and compared the display rates of the two volume data on normal cardiac structures. 【Results】The visualization rate of fetal four- chamber view（93.33% vs. 78.33%），left ventricular outflow tract view （87.22% vs. 75.56%），right ventricular outflow tract view（78.89% vs. 66.11%），three-vessel trachea view（84.44% vs.70.56%），aortic  arch（72.78%  vs. 60.00%），ductal  arch（81.11%  vs. 63.33%），3D  rendering of complete intracardiac  septa（81.67% vs. 60.56%），3D rendering of atrioventricular annulus（68.33% vs. 51.11%）and the average number of recognitions（80.97% vs. 65.69%）obtained by eSTIC were all significantly higher than those of STIC（all P<0.01）.【Conclusions】The volume data obtained by eSTIC technology can provide clearer structural information than STIC. The eSTIC technology can be used as an effective supplement to the two-dimensional scan clinically.
