Case report

A 22-year-old woman (G1P0), with non-contributive history, was referred to our antenatal unit at 22 weeks of her pregnancy for a routine ultrasound scan. Our examination revealed an isolated transposition of great arteries. 

Images 1, 2: The images show four-chamber view of the heart with the normal atrio-ventricular arrangement and ventricular sidedness.

Images 3, 4: The images show the outflow tracts of the heart. The aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. The image 4 shows parallel course of the great arteries.

Image 5: The image shows parallel course of the great arteries.

Video 1, 2: The videos show the outflow tracts - the pulmonary artery arises out of the left ventricle and the aorta arises out of the right ventricle.
