What does the 3VT view assess?

The key idea here is that this view looks at how the great vessels relate to the trachea in a single plane. In the three-vessel–trachea view you see the superior vena cava, the main pulmonary artery, and the ascending aorta arranged around the trachea. This setup lets you quickly assess whether the great vessels are in their expected spatial relationship and origin, which is crucial for spotting conotruncal or arch-related anomalies. This view is specifically about the vessels around the trachea, not about the four-chamber heart relationships, hepatic venous drainage, or the anterior–posterior orientation of the heart itself. So the description that emphasizes the arrangement of the great vessels relative to the trachea in one plane, including the SVC, pulmonary artery, and ascending aorta, matches what the 3VT view is designed to evaluate.
