The left atrioventricular (mitral) complex comprises of the annulus, the leaflets, the chordae tendineae and papillary muscles. The mitral valve is involved in many conditions such as stenosis, regurgitation, prolapse, rheumatic heart disease, endocarditis etc. Hence, detailed information of the dimensions of the valve is essential especially in surgical interventions such as reconstruction or replacement. The study aimed at measuring the various dimensions of the mitral valve complex. The study was conducted over a period of one year. Thirty adult hearts obtained from embalmed cadavers were used for the study. The mean width and height of anterior leaflet were 37.0 mm and 23.0 mm respectively. The mean width and height of posterior leaflet were 56.7 mm and 13.8 mm respectively. The mean circumference of annulus was 97.0 mm. The mean lengths of anterior and posterior leaflet chordae tendineae were 19.6 and 17.7 mm respectively.
