Abstract
Objective: To estimate the mean of morphometric values of the human aortic valve in the population of western Maharashtra. The morphometric variables include mean area and the circumference of the human aortic valve of both genders.
 Materials and Methods: The present study was carried out on 30 adult cadaveric hearts in the department of Anatomy at a tertiary care hospital in western Maharashtra. Heart and aortic arch were dissected according to standard dissection techniques. The aortic orifice and valves were exposed; pictures were taken keeping a plastic ruler alongside the periphery of the valve. The pictures were analyzed using Image J software to calculate circumference and area of the aortic valve.
 Results: The mean circumference of the aortic valve was 8.827 cm in males and 8.179 cm in females. The mean area of the male aortic valve was 5.365cm² and the female aortic valve is 4.641cm². The circumference results were found to be significant whereas the area results were not significant.
 Conclusion: The size of the aortic valve in the western Maharashtra region was found to be more as compared to other studies. The present study might help the cardiothoracic surgeons as well as the prosthetic valve manufacturing companies for the rough estimation of the aortic valve size.

Highlights
Cardiovascular system is one of the earliest system to develop in human body
Among the valvular heart diseases, Aortic Valve Disease (AVD) is the most common (44.3% VHD are AVD)(11).The overall prevalence of degenerative aortic valve disease has risen due to an increase in life expectancy(12),(13),(14)
Aortic valve disease generally manifests in the form of aortic stenosis or aortic regurgitation
Summary
Cardiovascular system is one of the earliest system to develop in human body It begins to develop in the middle of the third week when placenta alone cannot suffice for the nutritional requirements of the developing embryo (1). It develops from primary and secondary heart fields with primary heart field forming the atria, the left ventricle, part of right ventricle and secondary heart field forming outflow tracts and rest of the right ventricle (1). There are four valves namely two atrioventricular valves (tricuspid and bicuspid valves) and two semilunar valves (aortic and pulmonary valves). Tricuspid valve is situated between right atrium and right ventricle. The aortic and pulmonary valves are semilunar valves with each having three leaflets. The valves are responsible for unidirectional blood flow and their structural integrity is essential for the proper functioning of the heart
