aortic valve
- the valve between the left ventricle and the ascending aorta, consisting of three fibrous semilunar cusps (valvules), located in the adult in anterior, right posterior, and left posterior positions; they are named, however, in accordance with their embryonic derivation in which the anteriorly located cusp is the right cusp (above which the right coronary artery arises), the left posteriorly positioned cusp is designated as the left cusp (above which the left coronary artery arises), and the right posteriorly positioned cusp is designated as the posterior or noncoronary cusp.
Syn: valva aortae
