Abstract

Left atrioventricular orifice of heart is guarded by bicuspid Mitral valve. It is affected much in comparison to other heart valves in Rheumatic Heart Disease. Anatomy of this complex structure is altered in many pathological conditions and may require repair or replacement. The purpose of the study is to analyze its morphology and morphometry by conventional dissection method. Formalin fixed 20 adult heart specimens were collected irrespective of sex from Department of Anatomy, Govt. Tirunelveli Medical College,Tirunelveli. In this study the height and length of anterior leaflet was between 7.16 mm – 22.31mm and 12mm – 65.87 mm respectively. The height and length of posterior leaflet was between 5.40mm – 21.5mm and 10.90mm – 59.95mm respectively. Orifice circumference of mitral orifice is 6.2 to 10.5cm. Anterior leaflet were larger than the posterior leaflets. The results are correlated with other studies and concluded about its morphometry. This will help in multimodality imaging assessment and in planning surgery which may be either repair or replacement.
