Операции на корне аорты продолжают совершенствоваться. Для замены корня аорты используются как линейные клапансодержащие кондуиты, так и анатомичные (так называемые Вальсальва – графты). При этом нет четкого мнения, насколько важно использовать именно анатомичные клапансодержащие кондуиты. Ответ на этот вопрос возможно получить при сравнении трансклапанной гемодинамики линейного кондуита с трансклапанной гемодинамикой нативного корня аорты. Исследования в этой области помогут найти характеристики, которыми должен обладать новый клапансодержащий кондуит для обеспечения оптимальной гемодинамики.</p></sec><sec><title>Цель</title><p>Цель. Продемонстрировать способ протезирования структур корня аорты с имитацией его естественной геометрии, сделать доклад о преимуществах подобного вмешательства с позиции трансклапанной гемодинамики.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Выполнено экспериментальное исследование по изучению трансклапанной гемодинамики в протезе «Русский кондуит I» линейного дизайна с вшитыми в него аутоперикардиальными створками. Результаты сравнивались с эталонной гемодинамикой в нативном корне аорты с вшитыми в него створками той же формы, как и в изучаемом кондуите. По результатам исследования оказалось, что естественная геометрия корня аорты значимо влияет на трансклапанную гемодинамику, что выражается в меньших трансклапанных градиентах, меньших потерях энергии на открытии и закрытии створок, большей площадью открытия.</p></sec><sec><title>Результаты</title><p>Результаты. Экспериментальные данные мы экстраполировали на клинические результаты аналогичных операций в сопоставимых группах. Изучали результаты операции с использованием протеза «Русский кондуит». Операцией с сохранением корня аорты выступила симметричная неокуспидизация. По результатам исследования было продемонстрировано, что сохранение нативного корня аорты дает лучшую трансклапанную гемодинамику, что значимо влияет на обратное ремоделирование левого желудочка в среднеотдаленном периоде. С учетом этого сделан вывод о необходимости сохранять геометрию корня аорты при вмешательствах по его протезированию клапансодержащим кондуитом. В данной работе также представлен клинический случай использования нового протеза корня аорты «Русский кондуит II». Он использован для реконструкции корня аорты с восстановлением запирательной функции нативного аортального клапана. Приведено описание методики операции, непосредственные результаты, подробно описаны возможности подобного оперативного вмешательства.</p></sec><sec><title>Заключение</title><p>Заключение. Есть основания полагать, что применение разработанного протеза при операциях на корне аорты может давать гемодинамический результат, сопоставимый с нативным клапаном, при этом сама операция имеет потенциал к высокой воспроизводимости и стандартизации хирургической техники, что расширит ее применение.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Aortic root surgery continues to improve. Both linear valve-containing and anatomic (so-called Valsalva grafts) conduits are used for aortic root replacement. However, there is no clear opinion about the importance of using anatomical valve-containing conduits. The answer to this question can be obtained by comparing the transvalvular hemodynamics of a linear conduit with the transvalvular hemodynamics of the native aortic root. Research in this area will help to find the characteristics that a new valve-containing conduit should possess to provide optimal hemodynamics.</p></sec><sec><title>Objective</title><p>Objective. To demonstrate the method of aortic root structures prosthetics with imitation of its natural geometry, to report on the advantages of such intervention from the position of transvalvular hemodynamics.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. An experimental study of transvalvular hemodynamics in the prosthesis “Russian Conduit I” of linear design with autopericardial flaps sewn into it was performed. The results were compared with the reference hemodynamics in the native aortic root with sewn-in flaps of the same shape as in the studied conduit. The results of the study showed that the natural geometry of the aortic root significantly affects transvalvular hemodynamics, which is expressed in smaller transvalvular gradients, lower energy losses at the opening and closing of the flaps, and larger opening area.</p></sec><sec><title>Results</title><p>Results. We extrapolated the experimental data to the clinical results of similar operations in comparable groups. We studied the results of the operation with the use of the Russian Conduit prosthesis. The operation with the aortic root preservation was symmetrical neocuspidization. According to the results of the study it was demonstrated that preservation of native aortic root gives better transvalvular hemodynamics, which significantly affects the reverse remodeling of the left ventricle in the mid-term period. With this in mind, it is concluded that it is necessary to preserve the geometry of the aortic root during interventions for its prosthesis with a valve-containing conduit. This paper presents a clinical case of a new aortic root prosthesis “Russian Conduit II”. It was used for aortic root reconstruction with restoration of the locking function of the native aortic valve. The description of the surgical technique, immediate results, and the possibilities of similar surgical intervention are described in detail.</p></sec><sec><title>Conclusion</title><p>Conclusion. There are reasons to believe that the use of the developed prosthesis in aortic root surgeries can give hemodynamic results comparable with native valve, and the operation itself has a potential for high reproducibility and standardization of surgical technique, which will expand its application.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>реконструкция корня аорты</kwd><kwd>протез корня аорты</kwd><kwd>трансклапанная гемодинамика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aortic root reconstruction</kwd><kwd>aortic root conduit</kwd><kwd>transaortic hemodynamic</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">Mookhoek A., Korteland N.M., Arabkhani B., Di Centa I., Lansac E., Bekkers J.A. et al.
