Question

Which aortic leaflet is the superior one in the parasternal long axis view?

1) Anterior leaflet
2) Posterior leaflet
3) Septal leaflet
4) Cannot be determined

Answer 1

There is no 'superior' aortic leaflet in the parasternal long axis view on an echocardiogram; instead, the aortic valve cusps are described in relation to surrounding structures.

Step-by-step explanation:

In the parasternal long axis view on an echocardiogram, which aortic leaflet is the superior one? The answer to this question is that there is no specifically designated superior leaflet. Instead, in this view, you will see the right coronary (anterior) cusp and the non-coronary (posterior) cusp. The term 'superior' does not apply because the aortic valve cusps are more conventionally described in relation to the surrounding anatomical structures (e.g., the coronary arteries).

Therefore, when we talk about the aortic valve in the heart, it's important to remember that it, along with the pulmonary valve, is a semilunar valve. This means that they are structured to efficiently prevent the backflow of blood into the ventricles after contraction.
