Morphological features of fenestra and nodules on the aortic valve leaflets of humans

Abstract

The article presents the results of a morphological study on the characteristics of nodules and fenestrae in the semilunar cusps of the aortic valve, based on 38 autopsied adult human hearts. The study determines the position of the nodule on the semilunar cusp, identifies the main nodule shapes, and establishes their occurrence frequency. Data on the prevalence and distribution patterns of fenestrae in the semilunar cusps of the aortic valve are also provided.
