Figure 4. (A–D) Case 4. On the 4CV plane, the LV showed visible mitral stenosis, with a VSD and visible tricuspid regurgitation. The diameter of the aorta looked small and “tiny” due to the lack of blood flow. The 2 atria had nearly united. TVV footage showed an aorta that was smaller than the main pulmonary artery. In the transcerebellar plane, the shape of the head appeared abnormal, with the cisterna magna size showing 1.58 cm. SP – spine; Ao – aorta; LV – left ventricle; LA – left atrium; RV – right ventricle; RA – right atrium; VSD – ventricular septal defect; TV – tricuspid valve; MT – mitral valve; CM – cisterna magna; Cereb – cerebellum.
