Abstract
The authors conducted morphological studies of the structure of the semilunar heart valves in Siberian roe deer aged 1.5-2 years. The authors used the hearts of 3 males obtained in the Irkutsk region for research. The work used elements of access to semilunar valves, photographing and morphometry of structures of the mouth of the pulmonary trunk and aorta. The aortic valve of the Siberian roe deer is formed by three flaps (left, right and septal), where the morphometric parameters of the free edge of the left flap exceed the values of the other two. The greatest severity of the bottom part of the pockets is noted at the level of the left and right flaps. Their weight ranges from 4.2 ± 0.13 to 7.45 ± 0.27 mm. The authors noticed the severity of nodules on 55.6% of the flaps, where the nodule is shifted relative to the centre of the free edge of the flap by 11.4%. Three flaps represent the semilunar valve of the pulmonary trunk: left, intermediate and right, where the value of the height of the valve flaps is at the level of 12.2 ± 0.11 mm, width – 28.3 ± 0.29 and thickness – 0.18 mm. The bottom part is developed in all pockets of the valve, it covers almost the entire lumen of the mouth, and the most significant development was in the right bag – 5.9 ± 0.11 mm. Valve nodules were noted in 67% of the valves, where the percentage of deviation from the centre was similar to the aortic valve. By analyzing the indicators of the distance between the sash commissures and the width of its free section, it is possible to judge the severity of the elasticity of the wall of the pulmonary trunk and aorta. At the same time, the width of the free edge of the flap exceeds the value of the distance between the commissures at the pulmonary trunk valve by 1.4 and the aortic valve by 1.34 times.
