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.
