VARIANT ANATOMY OF THE SEMILUNAR LEAFLETS OF THE AORTIC AND PULMONARY VALVES BASED
H.A. Pasiuk, N.A. Trushel
The article presents contemporary domestic and foreign literature data
on the variant anatomy of the aortic and pulmonary semilunar leaflets.
The anatomical features 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.
