| Summary: | For the purpose of the definition of the features of anatomic reorganization of anterior ventricular heart walls inthe place of arise of papillary muscles at children with the full form of the transposition of the great vessels 31 specimenswith the given pathology from a birth till 11 months and 31 specimens of usually formed hearts of the same age group havebeen investigated. The distinguish features of abnormal hearts were: atrial and ventricular septal defects, patent ductus arteriosus.For reception of quantitative parameters of the object of the research - thickness of forward walls ventricles made themeasurement. The statistical analysis of the received data depending on age, type and quantity of communications is made.At a combination of a transposition with ventricular septal defect the thickening of right ventricular walls in the place of ariseof papillary muscles more often came to light. The transposition was accompanied by atrial septal defect, thinning of a leftventricular wall after 1 month was established. The transposition with patent ductus arteriosus and septal defects characterizedby thickening of wall of the right ventricle since 3 week. The combination of the transposition with ventricular and atrialseptal defects leads to the thickening of the wall of both ventricles.
