The right atrio-ventricular (tricuspid) valve is having three leaflets in majority of cases. However, in some cases it has shown only two leaflets or in few four leaflets. Accurate knowledge of morphometry and morphology is important in differentiating and treating various pathologies of the right atrio-ventricular (tricuspid) valve. Hence, the aim of the present study is to measure various dimensions of the right atrio-ventricular (tricuspid) valve and note any variations found. The dimensions were measured with the help of standard instruments. The data obtained was statistically analysed and compared with the available literature. The Mean results obtained were (in mm), circumference of right atrioventricular valve             annulus: - 10.2, width of anterior leaflet: - 4.9, width of posterior leaflet: - 3.8, width of septal leaflet: - 4.4, height of anterior leaflet: - 3.3, height of posterior leaflet: - 3.4, height of septal leaflet: - 4.8
