Целью данного исследования явилась оценка ротации на уровне базальных, верхушечных сегментов, папиллярных мышц и скручивания левого желудочка у здоровых детей и подростков, рожденных доношенными. Анализ выполнен у 86 здоровых детей в возрасте от 2 мес до 18 лет, рожденных доношенными, которые относились к группам здоровья I-II. До включения в исследование ни один ребенок в течение последних 6 мес не переносил острых респираторных вирусных инфекций. Индивидуальный анализ ротации левого желудочка на уровне базальных, верхушечных сегментов и папиллярных мышц выявил четыре варианта скручивания левого желудочка. 1-й тип (“взрослый”) встречался у 52 (60,5%) здоровых детей и подростков в возрасте от 2 мес до 18 лет. Для этого типа скручивания характерно разнонаправленное вращение базальных и верхушечных сегментов левого желудочка, то есть ротация на уровне базальных сегментов направлена по часовой стрелке, а на уровне верхушки - против часовой стрелки. 2-й тип (“детский”) - однонаправленное вращение против часовой стрелки на уровне базальных сегментов, папиллярных мышц и верхушки. Данный тип скручивания левого желудочка был зарегистрирован у 15 (17,4%) детей. Для 3-го типа характерно однонаправленное вращение против часовой стрелки базальных и верхушечных сегментов, а на уровне папиллярных мышц - по часовой стрелке. Данный вариант скручивания левого желудочка обнаружен у 10 (11,6%) здоровых детей. 4-й тип, выявленный в 9 (10,5%) случаях, характеризовался движением левого желудочка на уровне апикальных сегментов и папиллярных мышц по часовой стрелке, а на уровне базальных сегментов в 4 случаях - по часовой, а в 5 - против часовой стрелки. Не было обнаружено значимых различий в частоте встречаемости типов скручивания левого желудочка в зависимости от возраста и пола.

The aim of the study was to evaluate rotation at level of basal and apical segments, papillary muscles and twisting of left ventricle in healthy children and adolescents born full-term. 86 healthy children aged from 2 months up to 18 years old born full-term were included in to the study. None of children had any respiratory tract infection within last 6 months. Individual analysis of left ventricle rotation at level of basal, apical segments, and papillary muscles revealed four types of left ventricle twist. The 1st type (“adult type”) was diagnosed in 52 (60.5%) healthy children and adolescents aged from 2 months up to 18 years old. This type of twist was characterized by multidirectional rotation of left ventricle basal and apical segments. It was clockwise at level of basal segments and counterclockwise at level of apex. The 2nd type (“children type”) was characterized by unidirectional counterclockwise rotation at level of basal segments, papillary muscles, and apex. This type of twist was diagnosed in 15 (17.4%) children. The 3rd type was characterized by unidirectional counterclockwise rotation at level of basal and apical segments and clockwise at level of papillary muscles. This type of left ventricle twist was revealed in 10 (11.6%) healthy children. The 4th type revealed in 9 (10.5%) cases was characterized by left ventricle clockwise motion at level of apical segments and papillary muscles, clockwise motion at level of basal segments in 4 cases, counterclockwise motion at level of basal segments in 5 cases. There were not any significant differences in prevalence of left ventricle twist depending on gender and age.
