Location:
Between left ventricle and aorta; includes noncoronary (posterior semilunar), right coronary (semilunar) and left coronary (semilunar) cusps.

Function:
Opens during systole; blood is ejected from left ventricle into aorta.
Closes during diastole; prevents reflux from aorta into left ventricle.

Importance in cardiovascular diseases:
Aortic stenosis (genetic or acquired), aortic regurgitation.

Importance in device delivery:
Artificial valves - bioprosthetic (xenograft, homograft) and mechanical.

Lambl's Excrescence:
The whisker-like filiform structures, can be seen on some of the aortic valves.

Localización:
Entre el ventrículo izquierdo y la aorta. Constituida por 3 cúspides: no coronaria (semilunar posterior), coronaria derecha (semilunar) y coronaria izquierda (semilunar).

Función:
Se abre durante la sístole; la sangre se expulsa del ventrículo izquierdo a la aorta.
Se cierra durante la diástole; previene el reflujo de la aorta al ventrículo izquierdo.

Importancia en las enfermedades cardiovasculares:
Estenosis aórtica (genética o adquirida), insuficiencia aórtica.

Importancia en implante de dispositivos:
Válvulas artificiales: bioprotésica (xenoinjerto, aloinjerto) y mecánica.

Excrecencias de Lambl (Strands valvulares):
Estructuras filiformes en forma de bigotes, se pueden ver en algunas de las válvulas aórticas.
