Расширенная аннотация ANATOMIC REORGANIZATION OF THE PAPILLARY MUSCLES AND WALLS OF THE VENTRICLES IN THE PLACE OF THEIR OUTCOME AT THE COARCTATION OF THE AORTA Malov A.E., Vasiliev V.A. Donetsk national medical university M. Gorkiy national medical university, Donetsk, Ukraine, Illichya - Ave. 16, Donetsk, 83003, Ukraine [email protected] Abstract Background. For improvement of diagnostics and surgical corrections anomalies of the development of the heart requires continuous replenishment of anatomical knowledge. It causes need to continue morphological researches of the atrioventricular valves, one of which major components are papillary muscles. Methods and results. 28 human anatomical specimens with coarctation of the aorta from 20 weeks of the pregnancy till 1 year postnatal life are investigated. As comparative group we used 28 human anatomical specimens of the children similar age. In work applied methods of anatomic preparation, the topografoanatomic method and a morphometry. Measurements of the thickness of the walls of heart we performed in the place of outcome each papillary muscles. When studying papillary muscles we paid more attention his higher, width and thickness. Results of measurements entered in special protocols and performed to the statistical analysis with employment computer programs MedStat. Studying of thickness of walls of the left and right ventricles of hearts of the children in the place of the outcome papillary muscles, and morphometric dates of papillary muscles of the left and right atria-ventricular valves in anatomical specimens of usually formed hearts and at the coarctation of the aorta is carried out. Coarctation of the aorta on the predduktal type it was accompanied by increase in thickness of walls of the right ventricle in the place of the outcome papillary muscles (р<0,05), thickness of walls of the left ventricle didn't differ from normal hearts (р>0,05). At the aorta coarctation on the postduktal type the thickening of walls of the left ventricle in the place of the outcome papillary muscles was observed (р<0,05), whereas thickenings of walls of the right ventricle it wasn't revealed (р>0,05). The interrelation between width and thickness of the papillary muscles and morphometric parameters of thickness of the wall of the corresponding ventricle of the heart is established. Conclusions. As a result of the conducted research peculiarities anatomic reorganization of the papillary muscles and walls of the ventricles in the places of outcome papillary muscles are defined. Further studying of these aspects in the hearts with others congenital heart diseases is represented interest. Key words: coarctation of the aorta, normally formed hearts, papillary muscles, thickness of the walls of the ventricles, atria-ventricular valves.
