Родоначальником неокуспидизации принято считать S. Ozaki, однако методы расчета неостворки из перикарда предложены задолго до него. Методика японского профессора заключается в использовании специальных шаблонов. В данной статье представлен математический расчет створки, выполненный хирургами Сеченовского Университета, позволяющий не только существенно упростить процедуру, но и выполнять ее в тех центрах, где шаблонов Ozaki нет.</p></sec><sec><title> </title><p> </p></sec><sec><title>Резюме</title><p>Резюме </p></sec><sec><title>Цель</title><p>Цель: Описана оригинальная методика полной реконструкции аортального клапана аутоперикардом. Расчет формы неостворок осуществлен на основании данных о диаметре фиброзного кольца, которые могут быть получены как во время, так и до операции, что позволяет сократить время вмешательства, искусственного кровообращения и ишемии миокарда, а в конечном итоге добиться снижения ишемии головного мозга и снизить вероятность поздних осложнений.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: Проведено проспективное исследование 34 пациентов, оперированных по поводу порока аортального клапана в кардиохирургическом отделении Университетской клинической больницы № 1 ФГАОУ ВО Первый МГМУ им. И.М. Сеченова Минздрава России (Сеченовский Университет) в период с января 2020 г. по март 2023 г. Средний период наблюдения для всей когорты составил 14,1±7,7 мес. Средний возраст больных – 51±17 лет (19–78 лет). Гендерное распределение в общей группе: мужской пол – 50% (n = 17), женский – 50% (n = 17). Всем пациентам выполнено протезирование аортального клапана аутоперикардом без использования шаблонов (расчетным способом). 17 (50%) больным проведена изолированная коррекция порока аортального клапана, 11 (32,3%) – протезирование восходящей аорты, 5 (14,7%) – вмешательство на митральном клапане, в 3 (8,8%) случаях выполнено коронарное шунтирование. Стеноз аортального клапана отмечен у 11 (32,3%) пациентов, недостаточность – у 4 (11,7%), стеноз и недостаточность – у 19 (55,8%). Двустворчатый аортальный клапан выявлен у 18 (52,9%) больных. Все пациенты разделены на две группы: Komarov (изолированная коррекция порока аортального клапана) и Komarov Plus (коррекция порока аортального клапана с сопутствующей кардиальной патологией).</p></sec><sec><title>Результаты</title><p>Результаты: Не зарегистрировано случаев конверсии в стандартное протезирование аортального клапана. Зафиксировано два случая госпитальной летальности; по данным патологоанатомического заключения, смерть в обоих случаях наступила из-за осложнений, спровоцированных двусторонней полисегментарной пневмонией, вызванной SARS-CoV-2. Одному пациенту через 4 мес. после вмешательства потребовалась повторная операция вследствие развившегося эндокардита, возбудитель Streptococcus viridans. В среднеотдаленном периоде гемодинамические показатели, такие как пиковый градиент, средний градиент и пиковая скорость, составили 11,96±4,70, 5,88±2,07 мм рт. ст. и 168,19±30,56 см/с.</p></sec><sec><title>Заключение</title><p>Заключение: Конечный вид протеза служит анатомическим аналогом нативного клапана и обеспечивает достоверное снижение пикового давления, отсутствие регургитации на клапане после операции и увеличение площади эффективного отверстия. Данный метод можно рассматривать как безопасную альтернативу процедуре Ozaki, при которой створки выкраивают с помощью специальных шаблонов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Highlights</title><p>Highlights</p><p>We have described the outcomes of aortic valve replacement using autologous pericardium without special templates. Although S. Ozaki is considered by many to be the founder of neocuspidization technique, the methods for sizing of the neocusps were proposed long before him. The method of the Japanese professor involves using special templates. This article presents a mathematical formula to calculate neocusps` size, which significantly simplifies the procedure, and makes it possible to perform it in centers that do not possess Ozaki templates.</p></sec><sec><title> </title><p> </p></sec><sec><title>Abstract</title><p>Abstract </p></sec><sec><title>Aim</title><p>Aim: To describe an original technique of aortic valve replacement using autologous pericardium without templates. The calculation of the neocusps` size is based on the diameter of aortic annulus, which can be estimated both intraoperatively and preoperatively, helps to reduce the duration of surgery, CPB time and myocardial ischemia, and lower the rates of late complications.</p></sec><sec><title>Methods</title><p>Methods: The prospective study included 34 patients with aortic valve disease admitted to the Cardiac Surgical Department of the University Clinical Hospital No.1 of the First Moscow State Medical University named after I.M. Sechenov, Ministry of Health of Russia in the period from January 2020 to March 2023. The mean age of the patients was 51±17 years (from 19 to 78 years). Gender distribution in the total group was as follows: male 50% (n = 17), female 50% (n = 17). All patients underwent aortic valve replacement using autologous pericardium without templates (by calculating the neocusps` size). Isolated aortic valve replacement was performed in 17 patients (50%), ascending aorta replacement in 11 patients (32.3%), mitral valve intervention in 5 (14.7%), coronary artery bypass grafting in 3 (8.8%) cases. 11 patients (32.3%) had aortic valve stenosis, 4 patients (11.7%) had insufficiency, and 19 patients (55.8%) had both stenosis and insufficiency. Bicuspid aortic valve was detected in 18 patients (52.9%). All patients were divided into two groups: Komarov (aortic valve replacement only) and Komarov Plus (aortic valve replacement and treatment for concomitant cardiac pathology).</p></sec><sec><title>Results</title><p>Results: There were no cases of conversion to traditional aortic valve replacement using prosthetic valves. There were 2 cases of in-hospital mortality; according to medical records, death in both cases was due to complications provoked by double pneumonia caused by SARS-CoV-2. 1 patient required reoperation 4 months after the intervention due endocarditis caused by Streptococcus viridans. In the midterm follow-up period, hemodynamic parameters such as peak gradient, mean gradient, and peak velocity were 11.96±4.70 mm Hg, 5.88±2.07 mm Hg, 168.19±30.56 mm Hg.</p></sec><sec><title>Conclusions</title><p>Conclusions: The obtained valve prosthesis is anatomically analogous to the native valve and provides reliable peak pressure reduction, no postoperative regurgitation, and increased effective orifice area. The proposed method is safe and can serve as an alternative to the Ozaki procedure, in which the neocusps are outlined using special templates.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Аортальный клапан</kwd><kwd>Глутаральдегид</kwd><kwd>Реконструкция аутоперикардом</kwd><kwd>Неокуспидизация</kwd><kwd>Неостворки</kwd><kwd>Перикард</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Aortic valve</kwd><kwd>Glutaraldehyde</kwd><kwd>Autologous pericardial aortic valve reconstruction</kwd><kwd>Neocuspidization</kwd><kwd>Neocusp</kwd><kwd>Pericardium</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы заявляют об отсутствии финансирования исследования.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Otto C.M., Nishimura R.A., Bonow R.O., Carabello B.A., Erwin J.P. 3rd, Gentile F., Jneid H., Krieger E.V., Mack M., McLeod C., O'Gara P.T., Rigolin V.H., Sundt T.M. 3rd, Thompson A., Toly C. 2020 ACC/AHA Guideline for the Management of Patients With Valvular Heart Disease: Executive Summary: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.
