Case report

A 16-year-old woman, G1 P0, was referred to our antenatal unit at 23 weeks of gestation. She had non-contributive family or personal history.
The ultrasound examination showed a transposition of the great vessels. The aorta was arising from the right ventricle and ran parallel to the pulmonary artery which was arising from the left ventricle and bifurcated shortly after its origin. The pulmonary artery and aorta had a normal diameter. Doppler of the great vessels was normal. The amniocentesis showed normal karyotype.
Patient delivered at perinatology center and the neonate underwent cardiac surgery afterwards. The baby is doing well at the moment.

Images 1,2: Image 1 shows a 4-chamber view. Image 2 shows parallel orientation of the great arteries.

Images 3,4: Transposition of the great arteries, they run parallel to each other, there is no criss-crossing. Aorta arises from the right ventricle and pulmonary artery from the left ventricle.

Images 5,6: Image 5 shows a bifurcation of the main pulmonary artery into two branches; left and right pulmonary artery. Image 5 shows pulmonary artery, left outflow tract.

Image 7: Right, aortic outflow tract.
