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

In the parasternal long axis view, the aortic valve is typically visualized with the right ventricular outflow tract and the left ventricle behind it. The aortic leaflets are positioned in a way that provides a clear distinction among them based on their anatomical relationships.

The right aortic leaflet is considered the superior leaflet in this view because it is seen as the highest point of the aortic valve structure, closest to the viewer’s perspective in the echocardiography image. When examining the aortic valve from this angle, the right leaflet extends outward towards the right side of the image, making it appear as the uppermost or superior leaflet compared to the other leaflets, which may appear lower or more centrally positioned.

This anatomical orientation is significant for correctly identifying and assessing the function of each leaflet in echocardiography. Understanding the position of each leaflet aids in recognizing potential abnormalities or dysfunctions during an echocardiographic examination.
