Superb microvascular imaging at 15 weeks of gestation revealed prominent trabeculations characteristic of ventricular noncompaction in a fetus with complex congenital heart disease.
Case Report (n=1)
Superb microvascular imaging enables the early prenatal diagnosis of ventricular noncompaction at 15 weeks of gestation.

May enable early prenatal ventricular noncompaction detection; leaves open utility beyond this single case and requires validation.
We present a case of fetal atrioventricular block, heterotaxy, and ventricular noncompaction observed longitudinally from the first to early second trimesters using B-mode and Doppler imaging, including superb microvascular imaging. At 12 weeks of gestation, the atrial and ventricular rates were 133 and 67 beats/min, respectively, and dextrocardia was noted. At 15 weeks of gestation, detailed sonography revealed ventricular septal defect, interruption of the inferior vena cava, dilated azygos vein, and double-outlet right ventricle. In addition, superb microvascular imaging revealed irregular contours in the anatomical left ventricular wall, indicating prominent trabeculations of the ventricle, which were characteristic findings of ventricular noncompaction. At 21 weeks of gestation, intrauterine fetal death occurred, and the autopsy revealed complex congenital heart disease, including ventricular noncompaction.
