Transposition of Great Arteries : Clues on prenatal Diagnosis

Transposition of the Great Arteries (TGA) is a congenital heart defect in which the two main arteries, the aorta, and the pulmonary artery, are switched in their positions. Prenatal diagnosis of TGA is crucial as it allows for early intervention after birth. Routine fetal ultrasounds can provide the first clues. Suspicion arises when the normal cross over between the great arteries is not visualized. Blood flow patterns can be assessed with Doppler ultrasound. Other cardiac abnormalities might be detected during prenatal ultrasounds, such as a ventricular septal defect (VSD) often associated with TGA.
