ABSTRACT:

Introduction: The unimpeded forward flow of blood across the mitral orifice depends upon a coordinated interaction between the mitral annulus, leaflets, chordae tendinae & papillary muscle. Knowledge about the normal anatomy of mitral valve annular morphometry is important for assessing the valve pathologies and also in valve replacement surgery for a deceased valve

Materials and methods: 50 heart of embalmed adult human cadaver of both sex aged between 20-70 years were taken from the department of anatomy, VIMS & RC. Parameters measured were annular diameter, circumference, area of mitral valve by using vernier caliper, measuring scale, cotton thread & magnifying lens.

Results: In the present study mean value of mitral valve were, circumference of mitral valve was 8.19±1.01cm in males, 7.76±0.99 cms in females, diameter was 3.10±0.40 cm in males & 3.26±0.48 cm in females, area of mitral valve was 5.45±1.34 cm2   in males & 4.89±1.20 cm2 in females. All the parameters of mitral valve annulus like circumference, diameter & area of valve was more in males except in females the diameter was more. There was no significant difference between male & female values of mitral valve annulus.

Conclusion: Knowledge of normal measurements of the component parts of the mitral valve is essential for the surgeon during operation to assess the exact mechanical reason for valve insufficiency & in development & manufacture of prostheses for valvuloplasty.

Key words: Mitral Valve, Annulus, Bioprosthesis, Valve Replacement.
