Aim:  To study the morphometric of accessory leaflet of tricuspid valve.
Material and Methods: This study was carried out on 100 adult human hearts ranging in age from 20 to 65 years, because decomposition or putrefaction could occur during the medico-legal post-mortem examination, which was performed within nineteen hours of death to ensure that the morphology and morphometry of the heart were not altered. The following morphometric characteristics are measured: heart weight, tricuspid valve circumference, leaflet length, anterior leaflet, septal leaflet, posterior leaflet, and commissure attachment length. The weight of the heart was measured using an electronic weighing scale. The number of tricuspid valve cusps and their positions were recorded. All parameters' lengths were measured using non-stretchable surgical silk thread. The thread was straightened and measured using a metric ruler with a reading of 0.5 mm.
Results: The morphometric data were determined, and the average weight in grammes was 261.85±25.85, the circumference in mm was 96.85±9.87, and the average attachment length in mm was 29.58±4.25, indicating that the septal leaflet was the biggest of the three leaflets. The ASC was 5.77±1.88 mm, the SPC was 9.11±2.14 mm, and the PAC was 6.02±1.93 mm. The average of the ASC, SPC, and PAC was 6.97±1.98 mm. The characteristics evaluated were heart weight (g), tricuspid valve circumference (mm), attachment length of leaflets and commissures (mm), and height of three leaflets (mm). A direct association was found between the circumference of the tricuspid valve and the weight of the heart, attachment lengths of the leaflets, and the three commissures and leaflet height.
Conclusion: This work may be utilised as an essential tool in anthropological studies since it enabled cardiac surgeons and forensic specialists comprehend the anatomy of the tricuspid valve complex and the right design of valvular complex for transplantation.
