The procedure is characterized by excellent hemodynamic results in the short and long term in patients with tricuspid aortic valve (TAV). However, the question remains about the long-term results of the procedure and the frequency of reoperations in patients with BAV.</p> <p><bold>OBJECTIVE</bold><bold>:</bold> To analyze the midterm outcomes of the Ozaki procedure in patients with BAV.</p> <p><bold>MATERIALS AND METHODS</bold><bold>:</bold> Retrospective single-center, non-randomized, parallel-group study was conducted. Since January 2015 to October 1, 2023, the clinic performed 809 Ozaki procedures. The work included 540 patients with studied midterm and long-term outcomes for up to 5 years. Both isolated aortic valve replacement and combined operations with coronary artery bypass grafting and (or) correction of mitral and tricuspid valve defects were performed.</p> <p><bold>RESULTS</bold><bold>:</bold> Midterm mortality was 5.7% (<italic>n</italic>=3) in the group with BAV and 7.3% (<italic>n</italic>=36) in the group with TAV. Reoperation for aortic regurgitation was required in 16 patients (2.9%): 1 patient (1.9%) in BAV group and 15 (3.3%) in TAV group. Freedom from reoperations in patients with BAV after the Ozaki procedure for up to 5 years was 95.4%, in the group with TAV — 92.6%. The peak gradient on the aortic valve in the group with BAV was 16±7.3, in TAV group — 16.4±10.9. 5 years after surgery, the mean gradient on the aortic valve does not exceed 10 mm Hg.</p> <p><bold>CONCLUSION</bold><bold>:</bold> The Ozaki operation in patients with BAV is an effective and safe procedure in the midterm follow-up period.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Альтернативой пластическим операциям на двустворчатом аортальном клапане (ДАК) может служить протезирование створок аутоперикардом по методике Ozaki. Процедура характеризуется превосходными гемодинамическими результатами в краткосрочном и отдалённом периоде наблюдения у пациентов с трёхстворчатым аортальным клапаном (ТАК). Однако остаётся открытым вопрос об отдалённых результатах процедуры и частоте реопераций у больных с ДАК.</p> <p><bold>Цель. </bold>Оценить среднеотдалённые результаты процедуры Ozaki у пациентов с ДАК.</p> <p><bold>Материалы и методы.</bold> Проведено ретроспективное одноцентровое нерандомизированное исследование в параллельных группах. С января 2015 по 1 октября 2023 года в клинике выполнено 809 процедур Ozaki. В работу включены 540 больных с изученными среднеотдалённым результатами в сроки до 5 лет. Выполнялись как изолированное протезирование аортального клапана, так и сочетанные операции с аортокоронарным шунтированием и/или коррекцией порока митрального и трикуспидального клапана.</p> <p><bold>Результаты. </bold>Летальность в среднеотдалённые сроки составила 5,7% (<italic>n</italic>=3) в группе с ДАК и 7,3% (<italic>n</italic>=36) — в группе с ТАК. Повторная операция по поводу аортальной недостаточности понадобилась 16 (2,9%) больным: 1 (1,9%) пациенту в группе с ДАК и 15 (3,3%) — в группе с ТАК. Свобода от реопераций у больных с ДАК после процедуры Ozaki в сроки до 5 лет составила 95,4%, в группе с ТАК — 92,6%. Пиковый градиент давления на аортальном клапане в среднеотдалённом периоде в группе с ДАК составил 16±7,3, в группе с ТАК — 16,4±10,9. Через 5 лет после операции средний градиент на аортальном клапане не превышал 10 мм рт.ст.</p> <p><bold>Заключение.</bold> Операция Ozaki у больных с ДАК — эффективная и безопасная процедура в среднеотдалённом периоде наблюдения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ozaki</kwd><kwd>neocuspidation of the aortic valve</kwd><kwd>bicuspid aortic valve</kwd><kwd>tricuspid aortic valve</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>операция Ozaki</kwd><kwd>неокуспидализация аортального клапана</kwd><kwd>двустворчатый аортальный клапан</kwd><kwd>трехстворчатый аортальный клапан</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">de Kerchove L, Mastrobuoni S, Froede L, et al.
