Background: The right atrioventricular valve, also called the tricuspid valve, its blood flow in one direction from the right atrium to the left ventricle. Cardiac surgeons use the tricuspid valve's shape and size data to do heart surgery on people who have a tricuspid valve. In a valve replacement surgery, a prosthetic valve takes the place of the old valve. Prosthesis of the synthetic valve for understanding the Tricuspid valve annulus.

Materials and Methods: We conducted our study by dissecting 100 formalin-fixed human cadaveric hearts. The sex of the human was not specified. The heart was taken out of the pericardial cavity and put on display. The specimens collected were sequentially numbered from 1 to 100 and preserved in a 10% formalin solution. We cut open the tricuspid orifice and measured these dimensions. 1. Circumference of annulus of tricuspid valve. 2. Diameter of tricuspid valve. Measurements were taken using a scale, thread, and vernier calliper.

Results: annular circumference of tricuspid annulus was range from 9.8 cm. to 14.8 cm, average was 11.94±1.05 cm. Diameter of tricuspid annulus was range from 1.8 cm. to 4 cm, average was 3.12±0.47 cm.

Conclusion: These data may assist cardiac surgeons, invasive cardiologists, and the fabrication of synthetic (prosthetic) valves.
