Ультразвуковая характеристика миокарда у здоровых детей и больных с некомпактным миокардом

The data of echocardiographic examination of 52 children with non-compact myocardium, 50 children with disorders of the cardiovascular system and heart remodeling and 79 apparently healthy children (total 181 children) aged from 2 months up to 17 years 11 months are presented. Ultrasound features of normal myocardium have been revealed: in 56 (71%) of conditionally healthy children the left ventricular myocardial wall consisting of two layers, composed of compact and trabecular layer was visualized, trabeculation normally localized in the area of lateral wall and apical segments of the left ventricle, with age, the ratio of trabecular to compact layer decreased because of increasing the thickness of the compact layer. In children with non-compact myocardium, the value of ratio of trabecular layer of the compact layer in the group was significantly greater than in healthy children and children from comparison group and no increase in the thickness of a compact layer was noted with age. Forms of pathology of the cardiovascular and pulmonary systems, leading to remodeling of the heart, simulating the non-compact myocardium have been accentuated.
