case_images: Fetal ultrasound revealed the absence of ductus venosus (DV) with the UV directly draining into the right atrium (Figure 1(a)), consistent with the extrahepatic drainage type of ADV. The cardiothoracic area ratio was 36.5%, within the normal range of <40% (Figure 1(b)) and heart valve regurgitation was absent.
case_images: Abdominal computed tomography at 1 year of age. A Morgagni hernia (black star) can be seen, and the right atrium (asterisk) and inferior vena cava (arrowhead) are displaced on the ventral side.
