Abstract The main objective of this study was to investigate the diagnostic performance of FINE in generating and displaying 3 specific abnormal fetal echocardiography views such as left ventricular outflow tract (LVOT) view, right ventricular outflow tract (RVOT) view, and 3-vessels and trachea (3VT) view in fetuses with double-outlet right ventricle (DORV). In this prospective study, thirty fetuses diagnosed with DORV by fetal echocardiography in the second and third trimesters were enrolled. One or more STIC volume data-sets were collected from the 4-chamber view as initial view for each fetus, one optimal volume per fetus was selected for on-line analysis using FINE, and the diagnosis plane image was optimized using the Virtual Intelligent Sonographer Assistance (VIS-assistance).The visualization rates of 3 specific abnormal fetal echocardiography views of DORV and key diagnostic elements were calculated. One or more STIC volumes (n = 30 total) were obtained in 25 patients. A single STIC volume per patient was analyzed using the FINE method. FINE was able to successfully generate and display 3 specific abnormal fetal echocardiography views. The display rates of the 3 specific abnormal fetal echocardiography views (3VT, LVOT, RVOT) were 84.0%, 76.0% and 84.0%, respectively. By applying intelligent navigation technology to STIC volume data-sets, the FINE method can successfully generate three specific abnormal cardiac fetal echocardiography diagnostic views in fetuses with DORV, the FINE method can be used for screening and remote consultation of fetal DORV.

Introduction Fetal congenital heart disease (CHD) is the most common birth defect, occurring in approximately 0.8% to 1% of live births, and severe CHD is one of the leading causes of death in newborns and infants [1]. Double-outlet right ventricular (DORV)is a conotruncal anomaly found in a group of complex heart lesions that are defined as a condition in which both main arteries arise predominantly from the right ventricle; DORV occurs 0.09% of live births and accounts for 10% of CHD [2]. It has been reported that the incidence of chromosomal abnormalities is increased in fetuses with * Bowen Zhao [email protected] 1

DORV, and the overall prognosis for fetuses with DORV is poor, with a 69% mortality rate in infancy and a postsurgical mortality rate of 50%. This high mortality rate may be related to fetal e
