Aim We aimed to assess the accuracy and effectiveness of fetal cardiac screening for congenital heart disease ( CHD ) during the second trimester by general obstetricians in a non‐selected population. Methods In this multicenter, prospective cohort study of fetal cardiac screening, four‐chamber and three‐vessel views were recorded by obstetricians at 18–21 gestational weeks (GW). A total of 3005 fetuses that were scheduled for delivery at our institution were included. Results Thirty‐seven newborns were born with CHD (1.2%). On excluding 23 cases of ventricular septal defects, the prenatal detection rate of CHD was 42.8%. Although six cases (75.0%) of severe structural abnormality were diagnosed prenatally, the prenatal detection rate of valvular abnormalities was 0%. Conclusion One‐point ultrasound screening of the fetal heart using a combination of four‐chamber and three‐vessel views at 18–21 GW by general obstetricians in a non‐selected population may be useful for detecting severe structural abnormalities but not valvular abnormalities. However, this limitation may be improved by conducting another fetal cardiac screening at approximately 30 GW along with the routine use of color D oppler.
