Двустворчатый клапан аорты (ДКА) может сочетаться с генетическими синдромами развития, но педиатрические аспекты проблемы изучены недостаточно. Цель. Определить частоту ДКА по данным кабинетов ультразвуковых исследований (УЗИ) и охарактеризовать клинические и эхокардиографические аспекты двустворчатого клапана аорты. Материал и методы. Обследовано 19 пациентов с ДКА (17 детей и 2 взрослых). Для оценки возможных отдаленных последствий ДКА провели ультразвуковое исследование 45 взрослым пациентам: мужчин 25 (средний возраст 61,72 ± 1,42 лет), женщин 20 (средний возраст 64,9 ± 1,46 лет). Результаты. Частота ДКА по данным кабинетов УЗИ составляет 1 случай на 20 000–23 500 исследований. ДКА сочетался с генетическими синдромами дисплазии соединительной ткани (синдромы гипермобильности суставов, Марфана, Фримена – Шелдона и др.), регистрировался у близнецов. Средняя величина индекса эксцентричности створок ДКА составляла 3,5, стандартное отклонение – 1,1, стандартная ошибка – 0,274. У взрослых пациентов с ДКА отмечался кальциноз створок, что не выявлено в контрольной группе (р = 0,006). Выводы. ДКА может быть как случайной находкой, так и сочетаться с другой патологией. ДКА чаще обнаруживается у людей с наследственными синдромами развития. Наличие ДКА требует исключения генетических синдромов развития. Несмотря на сравнительную редкость ДКА в общей популяции, отдаленный прогноз может оказаться серьезным, что требует от педиатра организации междисциплинарного взаимодействия.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The bicuspid aortic valve (BAV) can be combined with genetic developmental syndromes, but the pediatric aspects of the problem have not been adequately studied. Goal. Determine the frequency of BAV from the data of the ultrasound examination rooms (ultrasound) and characterize the clinical and echocardiographic aspects of the bicuspid aortic valve. Material and methods. 19 patients with BAV (17 children and 2 adults) were examined. To evaluate the possible long-term consequences of BAV, 45 adults were examined: men 25 (mean age 61.72 ± 1.42 years), women 20 (mean age 64.9 ± 1.46 years). Results. The frequency of BAV according to the ultrasound examination rooms is 1 case per 20 000-23 500 studies. BAV was combined with genetic syndromes of connective tissue dysplasia (hypermobility syndromes of joints, Marfan, FreemanSheldon, etc.), registered in twins. The average value of the eccentricity index of the BAV leaflets was 3.5, the standard deviation was 1.1, the standard error was 0.274. In adult patients with BAV, calcification of the valves was observed, which was not detected in the control group (p = 0.006). Conclusion. BAV can be both an accidental finding, and be combined with another pathology. BAV is more often found in people with hereditary developmental syndromes. The presence of BAV requires the exclusion of genetic developmental syndromes. Despite the comparative rarity of BAV in the general population, a remote prognosis may be serious, which requires the pediatrician to organize interdisciplinary interaction. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>аорта</kwd><kwd>клапан</kwd><kwd>аномалии клапана</kwd><kwd>дисплазия соединительной ткани</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aorta</kwd><kwd>valve</kwd><kwd>valve anomalies</kwd><kwd>connective tissue disorders</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">Braverman A.
