Description

The tricuspid valve (valvula tricuspidalis) consists of three somewhat triangular cusps or segments.

The largest cusp is interposed between the atrioventricular orifice and the conus arteriosus and is termed the anterior or infundibular cusp. A second, the posterior or marginal cusp, is in relation to the right margin of the ventricle, and a third, the medial or septal cusp, to the ventricular septum.
