Constitutional Anatomy of the Right Atrium of the Human Heart

Abstract

The study of the features of the anatomical structure of the posteroinferior department of the right atrium of human in the aspect of conducting the operation of radio-frequency ablation during the atrial disturbances of rhythm is actual task in the aspect of contemporary interventional cardiac surgery. On the first stage 120 preparations of human heart (60 women and 60 men) were investigated. At the second stage the magnetic resonance imaging (MRI) was executed for 60 examined person (36 men and 24 women). The third stage of work consisted in performance intraoperative three-dimensional reconstruction of the right atrium at 60 people in the conditions of interventional X-rays operating among which were 31 men and 29 women. As a result of the conducted analysis statistically meaningful distinctions of anatomic structure of posteroinferior department of right atrium are established at persons with the different types of build. The long posteroinferior department ] of right atrium above the short (respectively 59,4% and 40,6%) prevails at pyknic body type , at that time the short posteroinferior department of right atrium meets at asthenic body type reliable more often (respectively 60,4% и 39,6%). Results of research of anatomical structure of posteroinferior department of right atrium by a sectional method, МРI and electrical and anatomical mapping of Carto XP at people with the different kinds of body type are comparable, that testifies to the sufficient degree to authenticity in interpretation of data of anatomical structure of posteroinferior department of right auricle by the methods of lifetime visualization.
