A 34-week-old foetus with a criss-cross heart. A 34-week-old foetus had a echocardiography at 22 weeks of gestation that suggested the presence of transposition of the great arteries (D-TGA) and ventricular septal defect (VSD). Follow up foetal echocardiography at 34 weeks of gestation was limited because of increasing maternal subcutaneous oedema and obesity. An axial SSTSE image of the maternal abdomen demonstrating oedema of the subcutaneous soft tissues (A, arrow). SSFP coronal and axial view images showing the right ventricle located superiorly (B, RV), the horizontal ventricular septum with a VSD (B, open arrow), the right atrium (B,C RA) connected to the right ventricle (B,C RV) in a right-to-left direction (B,C arrow), and the left atrium (LA) connected to the left ventricle (LV) in a posteroanterior direction (C, open arrow). A postnatal enhanced cardiac MR image showing a criss-cross heart (same as the prenatal cardiac MRI). The right ventricle was located superiorly (D, RV), the horizontal ventricular septum with a VSD (D, arrow), the right atrium (D, RA) was connected to the right ventricle (D, RV) in a right-to-left direction (D, open arrow). The left atrium (LA) was connected to the left ventricle (LV) in a posteroanterior direction.
