Structural features and correlation of linear dimensions of the valvular apparatus of the heart in men and women of mature age

Abstract

The material for the study was 259 hearts of people of both sexes aged 21 to 92 years who died from causes not related to diseases of the cardiovascular system. In each particular case, the circumference of the left and right atrioventricular orifices, aorta and pulmonary trunk, as well as the length and height of the cusps of the two and tricuspid valves of the heart and the semilunar valves of the aorta and pulmonary valves were investigated under standard conditions. We studied the height and weight of the investigated, calculated body mass index. The study found that body mass index was higher in women than in men. The dimensions of the circumference of the left and right atrioventricular orifices, aorta and pulmonary trunk openings, the length and height of the cusps of the two and three leaved valves and the semilunar valves of the aorta and pulmonary trunk are larger in men than in women. Correlations were found from the length of the floor and the height of the anterior cusp of two and three leaved heart valves, and only the length of the hind cusps of these same valves. It was also established that the length and height of the posterior valve of the aorta valve, as well as the length of the left aortic valve valve and the length of the anterior semilunar valve of the pulmonary trunk are more pronounced in men than in women. With age, men showed an increase in the size of the aortic circumference, the height of the back sash of the tricuspid valve, the length of the right and back semilunar aortic valve, and the height of the right and left semilunar aortic valve. In women with age, there was a tendency to increase the size of the height and length of the posterior cusp of the double heart valve, the height of the posterior cusp of the tricuspid valve of the heart, as well as the height of the posterior semi lunar valve of the aorta and the height of the front semi lunar valve of the pulmonary trunk.
