Cusps of heart valves

Cusps of heart valves
Base of ventricles exposed by removal of the atria. (Valves visible on top of heart.)
Aorta laid open to show the semilunar valves. (Note that captions don't align with current terminology.)

The cusps of the heart valves serve to seal the heart valves when closed. There are three cusps for each valve except for the mitral valve, which has only two (hence its alternate name, "bicuspid valve").

"Nodules" are located at the tip of the valve, to form a tighter seal.

Semilunar valves

Nowhere in the literature does it describe the echocardiographic location of each pulmonary valve. According to researcher and professor Dr. Paul Michael, in the RVOT view the anterior and and right cusps can be viewed.
