Материал и методы исследования: в работу включено 88 детей в возрасте от 1 года до 5 лет, рожденных глубоконедоношенными с очень низкой и экстремально низкой массой тела. Группу сравнения составили 46 здоровых детей аналогичного возраста, рожденных доношенными. Меха ника левого желудочка изучена путем оценки вращения левого желудочка на уровне базальных сегментов, папиллярных мышц, верхушки и скручивания с помощью технологии двухмерной спекл-трекинг эхокардиографии. Результаты исследования: выделено четыре типа скручивания левого желудочка как у здоровых доношенных детей, так и у детей, рожденных глубоконедоношенными. Распределение типов скручивания левого желудочка у детей в возрасте от 1 года до 5 лет, рожденных с низкой, очень низкой и экстремально низкой массой тела, отличалось от детей, рожденных доношенными. Первый (“взрослый”) тип скручивания левого желудочка выявлен у 46,59% детей, рожденных глубоконедоношенными, и у 67,39% здоровых доношенных детей. “Детские” (второй и третий) типы по час тоте не различались между детьми обеих групп (11,36 и 15,91% против 13,04 и 15,22% соответственно). Четвертый тип (отрицательная апикальная ротация) значительно чаще обнаружен у детей, рожденных глу боконедоношенными (26,14 против 4,37%, P = 0,01). Не выявлено различий в час тоте выявленных типов скручивания левого желудочка в зависимости от пола ребенка среди детей, рожденных глубоконедоношенными. Выявлена связь скручивания левого желудочка с массой тела при рождении (r = 0,53, P = 0,003) у детей, рожденных глубоконедоношенными, в возрасте от 1 года до 3 лет.</p></abstract><trans-abstract xml:lang="en"><p>Objective: To assess the left ventricular mechanics during postnatal ontogenesis in preterm children with very low and extremely low birth weight. Material and methods: 88 children aged from one to five years old, born extremely prematurely with very low and extremely low body weight (the main group), were examined. The control group consisted of 46 healthy children of the same age, born full-term. Left ventricular mechanics was studied by evaluating left ventricular rotation at level of basal segment, papillary muscle, and apex and left ventricular twist using two-dimensional speckle-tracking echocardiography. Results: There are four types of left ventricular twist both in healthy full-term children and in children born extremelypremature. The distribution of left ventricular twist types in main and control group was different. The first type (adult type) of left ventricular twist was detected in 46.59% of children born with extreme prematurity and in 67.39% of healthy full-term children. There were no significant differences in incidence of children’s types of left ventricular twist (second and third types) between the groups (11.36 and 15.91% vs 13.04 and 15.22%, respectively). Incidence of the fourth type of left ventricular twist (negative apical rotation) was significantly higher in infants born extremely prematurely in comparison to full-term infants (26.14% vs 4.37%; P = 0.01). There were no differences in incidence of different types of left ventricular twist according to gender among children born extremely premature. The significant correlations between left ventricular twist types and birth weight (r = 0.53; P = 0.003) were found among children born with extreme prematurity aged from one to three years old.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>двухмерная спеклтрекинг эхокардиография</kwd><kwd>ротация левого желудочка</kwd><kwd>скручивание левого желудочка</kwd><kwd>механика левого желудочка</kwd><kwd>недоношенные дети</kwd><kwd>дети</kwd><kwd>рожденные с очень низкой массой тела</kwd><kwd>дети</kwd><kwd>рожденные с экстремально низкой массой тела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>2D speckle tracking echocardiography (imaging)</kwd><kwd>left ventricular rotation</kwd><kwd>left ventricular twist</kwd><kwd>left ventricular mechanics</kwd><kwd>premature infants</kwd><kwd>children with very low birth weight</kwd><kwd>children with extremely low birth weight</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Fyfe K.L., Yiallourou S.R., Wong F.Y., Horne R.S.
