Background and Objective: The right atrioventricular valve is the largest of all the heart valve. From a functional standpoint the term ‘atrioventricular valve apparatus/complex’ is more appropriate. The tricuspid valve is often called the “forgotten valve” or “lost valve” because it is relatively understudied compared to the other cardiac valves. The normal data of the tricuspid valve complex is of great clinical importance in the light of progress in cardiosurgery. The right atrium communicates with the right ventricle through right atrioventricular orifice, which is guarded by right atrioventricular valve. The objectives of the present study are to measure frontal, sagittal dimensions, circumference, right atrioventricular orifice area, height of anterior, posterior & septal leaflet, average number of chordae tendinae attached to anterior leaflet and average length of chordae tendinae attached to anterior leaflet of the Tricuspid valve. Methods: The study sample consists of 50 formalin fixed adult human heart available in the Department of Anatomy & Forensic department of NMCH Patna. The parameters were noted meticulously and the data processed. Conclusion: The results of the present study show that the morphometric measurement of Tricuspid Valve will serve as reference data for further studies, clinical use in patients with various cardiac abnormalities and construction of bioprosthetic valves for tricuspid repair.
