The tricuspid valve is on the right side of the heart, between the right atrium and the right ventricle. The normal tricuspid valve usually has three leaflets and three papillary muscles. Tricuspid valves may also occur with two or four leaflets, and the number may change during life.
Valves
- 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.
- A third, the medial or septal cusp, to the ventricular septum.
Pathology
A small amount of leakage or regurgitation is not uncommon in the tricuspid valve. It is a common valve to be infected (endocarditis) in IV drug users. More on [ Tricuspid valve ]
