Prenatal diagnosis of tetralogy of Fallot remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3‐vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of tetralogy of Fallot. In addition, we compared its sensitivity to that of the traditional outflow tract views for detection of tetralogy of Fallot. We found that both views were abnormal in all fetuses with tetralogy of Fallot, showing reversed aortic‐to‐pulmonary valve and aortic arch isthmus‐to‐ductus arteriosus ratios in the outflow tract and 3‐vessel and trachea views, respectively. However, as a single measured marker, the enlarged aortic arch isthmus on the 3‐vessel and trachea view appears to be the most sensitive for tetralogy of Fallot.
