The tricuspid valve might be of lesser importance in acquired heart disease but it often plays a primary role in congenital heart defects, especially in long-term outcomes. This chapter reviews the anatomy of the tricuspid valve, along with its embryological development. The tricuspid valve connects the right atrium and right ventricle, electrically isolates the two cardiac chambers, and maintains unidirectional blood flow. The valve complex consists of the annulus, usually three valve leaflets, the supporting chordae tendineae, and the papillary muscles. The number, length, and shape of the chordae tendineae and the papillary muscles are extremely variable. This can be of clinical significance since dysfunctional papillary muscles and dysplastic chordae can be important causes of valve dysfunction.
