Morphometrical Study of Mitral Valve

25 Male Cadveric hearts preserved in formalin in the dept of Anatomy dissection theatre of Dr V.M. Govt Medical College Solapur were studied metrically and morphologically.

1) The mean value of the mitral valve Circumference was 8.97 cm with (SD ± 0.7). 2) The mean value of length of anterior leaf let was 1.8 cm and that of posterior leaf let was 1.4 cm. 3) Thickness of both ant and posterior leaflets was having same mean value of O.2 cm(SD ± 0.44cm). 4) Length of papillary muscle i.e. mean length of anterio- lateral Papillary muscle was 1.8 cm (SD±0.3) and post. Med. Papillary muscle was 1.6 cm(SD±0.3). There all observations were more or less in agreement with previous workers^1,2 but Incidence of heads of papillary muscle differed with previous workers¹.

Morphologically the leaf lets were smooth, Crescent shaped and shape of annulus was Saddle shaped or ‘D’ Shaped and non-planar. Both papillary muscles with intact chorda tendane were observed which indicates normalcy of “Mitral Valve”
