Abstract To evaluate the feasibility of the use of STIC technology during routine obstetric scans as a screening program for congenital heart disease (CHD) and the influence of professional experience in those exams. Methods: 64 pregnant women with a normal fetal heart at gestational age between 20 and 34 weeks and 12 physicians participants divided in two groups: Group1- ?STIC specialist? and Group 2- ?STIC non-specialist?. STIC volume acquisition was performed during routine scans. Volumes were analyzed off-line to obtain the five axial views for optimal fetal heart screening: abdominal situs, four-chamber view (4CV), outflow tract views (OTV), three vessels and trachea view (3VT). Results: STIC volume acquisition was successful in 97.3% of cases in which it was attempted (Group 1: 100%, group 2:95%). 197 STIC volumes were used in this study. In 71%, it was possible to demonstrate 4CV and OTV (Group 1:88.9%, group 2:58.6%). 4CV, OTV and 3VT were visualized in 55.3% of the volumes dataset (Group 1:74.1% and group 2:42.2%). In 49% of volumes, all the five views for optimal fetal heart screening were seen (Group 1:67%, group 2: 36%). Conclusion: We believe that STIC can be used as a tool to improve the cardiac screening examination of the fetus. In 71% of the volumes used in this study, we could obtain 4CV and OTV, and those images have a detection rate of CHD of 70-86%. Professional experience was the most important influence in the image quality of the STIC volume.
