Больший размер имплантированного протеза более благоприятен для систолической функции и более полного регресса гипертрофии левого желудочка. В части случаев это может быть обеспечено только расширением заплатой выводного тракта левого желудочка. Цель. Сравнить непосредственные результаты между группой изолированного протезирования механическим клапаном, входящим в узкое аортальное кольцо, и группой с применением задней аортопластики, обеспечившей вмещение большего размера механического клапана. Материалы и методы. В 2015&amp;ndash;2023 гг. протезировали аортальный клапан 78 взрослым пациентам с узким аортальным кольцом (17&amp;ndash;21 мм). Группа изолированного протезирования составила 56 пациентов, группа с задней аортопластикой составила 22 пациента. Результаты. В непосредственном послеоперационном периоде группа с задней аортопластикой имела преимущества: по индексу Rashimtoola S.H. (1,34 &amp;plusmn; 0,2 против 1,06 &amp;plusmn; 0,14 см2/м2), по пиковому градиенту давления (20,77 &amp;plusmn; 6,61 против 29,33 &amp;plusmn; 8,2 mm Hg), среднему градиенту давления (10,61 &amp;plusmn; 3,23 против 14,93 &amp;plusmn; 4,29 mm Hg) на протезах, по индексу ударного объема левого желудочка (29,0 &amp;plusmn; 6,56 против 28,85 &amp;plusmn; 7,81 мл/м2). Выводы. Применение аортопластики дает лучшие гемодинамические результаты. Обоснованная доля задней аортопластикой при узком аортальном кольце составляет 28,2&amp;nbsp;% случаев.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The larger size of the implanted prosthesis provides more favorable conditions for systolic function and more complete regression of left ventricular hypertrophy. In some cases, this can only ensure expansion of the left ventricular outflow tract with a patch. Aim. To compare the immediate results between a group with an isolated mechanical valve replacement inserted into a narrow aortic annulus and a group with a posterior aortoplasty that accommodated a larger mechanical valve. The reasonable proportion of posterior aortoplasty for a narrow ring is 20&amp;ndash;30 % of cases. Materials and methods. In 2015&amp;ndash;2023, 78 adult patients with a narrow aortic ring (17&amp;ndash;21 mm) underwent aortic valve replacement. The isolated prosthetic group consisted of 56 patients, the group with posterior aortoplasty consisted of 22 cases. Results. In the immediate postoperative period, the group with posterior aortoplasty had advantages in: Rashimtoola S.H. index (1,34 &amp;plusmn; 0,2 versus 1,06&amp;nbsp;&amp;plusmn;&amp;nbsp;0,14 см2/м2), significantly lower peak pressure gradient (20,77 &amp;plusmn; 6,61 versus 29,33 &amp;plusmn; 8,2 mm Hg), mean pressure gradient (10,61 &amp;plusmn; 3,23 versus 14,93 &amp;plusmn; 4,29 mm Hg) on the prostheses, and left ventricular stroke volume index (29,0 &amp;plusmn; 6,56 versus 28,85 &amp;plusmn; 7,81 мл/м2). Conclusions. The use of aortoplasty gives better hemodynamic results. The reasonable proportion of posterior aortoplasty for a narrow aortic ring is 28.2 % of cases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>корень аорты</kwd><kwd>задняя аортопластика у взрослых</kwd><kwd>протезирование аортального клапана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aortic root anatomy</kwd><kwd>posterior aortoplasty in adults</kwd><kwd>aortic valve replacement</kwd></kwd-group></article-meta></front><back><ack><p>Работа выполнена без внешних источников финансирования.</p></ack><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>Ассоциация сердечно-сосудистых хирургов России. 2021.
