Morphometry of Mitral Valve and its Variations
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 6
Abstract
Introduction: Among all four valves in The human Heart, Mitral Valve connects Lt. Atrium with Lt. Ventricle. Detailed structural anatomy of it is essential for surgeons doing mitral homograft replacement as well as for corrective surgeries. Material and Methods: 52 formalin fixed human hearts were studied, procured from cadavers in the Department of Anatomy, Motilal, Nehru,Medical College, Allahabad. Left ventricle and mitral valves were dissected and studied. Results: In 5(9.61%) heart specimens we have found 3 cusps instead of 2(Bicuspid) cusps of mitral valve, we have found 3 prominent indentations considering it as commissures as they were deep, having attached chordae from separate papillary muscles. Average circumference of Mitral Valve is 8.136 cms (Table-1) and average height of Anterior cusp and Posterior cusp is 2.034 and 1.012cms respectively (Table-2) in eastern uttar Pradesh population Comclusion: Average annular circumference is less in north Indians as compared to other population and average height of anterior and posterior cusps is almost matching with other populations.
