Three vessel and trachea view

The three vessel and trachea view (or 3VT view) is one of the fetal echocardiography views. In this view, aortic and ductal arches are combined into the DAo and appear as a V-shaped confluence. Both arches tend to be of similar size and are located towards the left of the trachea. The thymus is also seen. On colour Doppler interrogation, the flow in both arches should appear in same direction. This view allows comparison of both arches as well as assessment of aortic arch abnormalities (aortic arch hypoplasia and coarctation of the aorta etc).
