The tricuspid valve is subject to multiple variations with respect to the modal variety, knowledge of these variations is essential to the practice of cardiac surgery. The objective of this work was to identify the anatomical variations of the tricuspid valve and to clarify their implications.

This was an anatomical study by dissection of 21 formalin hearts, taken from Senegalese melanoderms anatomical subjects. The morphometry of the cusps and the annulus was studied and analyzed statistically.

The ring shape was circular in 10 hearts and elliptical in 11 with an average diameter of 3.86 cm and an average circumference of 12.1 cm. Fifteen anatomical pieces contained 3 cusps; 2 had 2 and the rest had 4. Statistical analyzes revealed that as the number of cusps increases, the width of the anterior cusp decreases.

This work made it possible to highlight the anatomical variations of the tricuspid valve concerning the cusps and to establish averages concerning the morphometric values of the latter as well as their impact in its surgical management.
