TLDR
Current domestic and foreign literary data on the variant anatomy of the aortic and pulmonary semilunar leaflets are presented, which include thickening and changes in cellular and fibrous composition depending on the age of the individual.
Abstract
The article presents contemporary domestic and foreign literary data on the variant anatomy of the aortic and pulmonary semilunar leaflets. The anatomical features are shown include the differences in the structure and number of semilunar leaflets, of their structural asymmetry, and the variation in morphometric characteristics. Attention is given to the changes in anatomical terminology since 2019, which now distinguishes the valvular complex of the heart, consisting of the fibrous skeleton of the heart, atrioventricular valves, and the roots of the aorta and pulmonary trunk. It is shown that there is a limited amount of data in the literature regarding the sizes and positions of nodules on the semilunar leaflets of the aortic and pulmonary valves. The article focuses on the prevalence of openings and their morphometric characteristics in the semilunar leaflets of the studied valves. Histological features of the semilunar leaflets are presented, which include thickening and changes in cellular and fibrous composition depending on the age of the individual.
