Objectives Isolated total anomalous pulmonary venous return (iTAPVR) is a congenital heart disease which is most difficult to detect prenatally. However in recent years, the number of prenatally-diagnosed cases is increasing. The objective of this study to clarify the ratio of fetal diagnosis for iTAPVR in recent years, and the reasons for referral. Methods We retrospectively reviewed the cases of iTAPVR treated in our institution from 2014 to 2018. Results Ratio of fetal diagnosis for iTAPVR was 6/14 (43%) in 2014-18. Type of prenatallydiagnosed iTAPVR was supacardiac in 3, and infracardiac in 3 cases. The reasons for referral vary, not only the wide space posterior to left atrium, but also the additional vessels in three vessel trachea view (3VTV), and the abnormal Doppler waveform of peripheral pulmonary veins. Conclusion Ratio of fetal diagnosis for iTAPVR has improved dramatically in recent years. Screening from the multiple points is important to detect iTAPVR. Figure 1. Flat Doppler flow pattern of PV is important not to miss iTAPVR with severe PVO. Figure 3. Additional vessel in 3VTV (arrow) is important to detect the supracardiac iPAPVR. To differentiate it from PLSVC, Find the innominate vein and confirm drainage of the abnormal vein to inn. vein. Left PV
