Зависимость между формой ушка левого предсердия и формой сердца взрослого человека

Abstract

Abstract Background: Scientific knowledge about the anatomic structure of the auricle of left atrium are important for cardiology and cardiosurgery. So, according to the literature, the auricle of left atrium of the vermiform can lead to sinus rhythm disorders and to thrombosis, which requires isolating with an occluder. The development of atriomegaly of left atrium is possible in the presence of malformation of the mitral valve. The data on the size of the orifice of the auricle of left atrium have affect to the features of surgical access to the heart cavity. With these considerations in mind, scientific knowledges about anatomy of left atrium is relevant. Material and methods: 113 preparations of hearts of adult people have been studied, which were received by the Department of Normal Anatomy for educational purposes. During the study by the macroscopic method, morphometric sizes of the heart and auricle of left atrium were established. Then statistical analysis was performed. Results: Three forms of the auricle of the left atrium have been described: a vermiform, lobate, and cockscomb. Three forms of the heart were identified: short wide hearts, normal shape, long narrow hearts. Conclusions: The relationship between the form of the auricle of left atrium and the form of the heart has been established.
