Application of Ultrasound in the Prenatal Diagnosis of Fetal Transposition of the Great Arteries

  Objective  To investigate the diagnositic value of ultrasonography in fetuses with transposition of the great arteries.

  Methods  In a retrospective analysis, the sonographic findings of 4 fetuses with transposition of the great arteries who were treated in Peking Union Medical College Hospital from March 2010 to July 2013 were reviewed and compared with the pathological findings.

  Results  Of these 4 fetuses with transposition of the great arteries, a normal four-chamber view was seen in 3 cases and ventricular septal defect in 1 case. At the level of left and right ventricular outflow tract, abnormal ventricular-arterial connection was detected. At the level of 3 vessel and tracheal view, two vessels rather than three were seen in all cases.

  Conclusions  Fetal transposition of the great arteries has specific echocardiographic findings. The left and right outflow tract view and the three vessel and tracheal view are helpful in the accurate diagnosis.
