1040 Morphometric Study of Human Aortic Valve along with a Case of Bicuspid Aortic Valve in Cadaver

The morphometric data pertaining to the aortic valve is very relevant for aortic valvular diseases and prosthetic valve transplant thereof, but such data is variably described in autopsy studies which prompted us to study the same in cadaveric hearts of Indian population. We also present a case of symmetrical bicuspid aortic valve (BAV). Thirty formalin fixed cadaveric hearts of both genders, aged between 58 -83 years were taken. Guidelines for using cadaver for teaching and research were followed. Various attributes of the aortic valve viz. number, width and height of cusps, number and depth of aortic sinuses, number of coronary ostia were recorded. All measurements were made with Vernier callipers and statistical analysis was performed with Microsoft Excel version 2019. The mean cusp heights were 18.28±0.54 mm, 19.52±0.34 mm and 20.91±0.46 mm respectively for the right, left and the non-coronary cusps. The mean depths of the aortic sinuses were 17.3±0.68 mm, 16.8±0.74 mm and 15.9±0.32 mm respectively for the right, left and the non-coronary sinus. We also observed symmetrical BAV in 1 (2.5%) out of the 30 specimens but the death of the individual was unrelated to the presence of the anomaly. The morphometric parameters obtained in the study would help in transplanting prosthetic aortic valve with greater compatibility. The chance of encountering congenital BAV even in individuals with no cardiac ailment should be borne in mind.
