Background: A double-outlet left ventricle is a very rare congenital heart anomaly. There have been only two reports on the prenatal diagnosis of a double-outlet left ventricle.
Case description: In a fetal case of cystic hygroma with generalized skin edema, agenesis of the ductus venosus, and reverse end-diastolic umbilical artery velocity waveforms at 13 weeks of gestation, a double-outlet left ventricle and ventricular septal defect were clearly depicted with transvaginal SlowflowHD. Intrauterine fetal death occurred 6 days later.
Conclusion: Transvaginal SlowflowHD may be a useful modality to diagnose complicated congenital heart anomalies, such as a double-outlet left ventricle with a ventricular septal defect, in the first trimester of pregnancy.
