Клапаносохраняющее протезирование корня аорты с реимплантацией аортального клапана (АК) (операция Дэвида) характеризуется невысокими рисками тромбоэмболических и инфекционных осложнений. Отрицательными чертами являются большая длительность, риски геморрагических осложнений, оператор-зависимость. С целью повышения скорости выполнения, улучшения воспроизводимости и снижения оператор-зависимости мы разработали устройство для интраоперационного позиционирования створок АК. Оно представляет собой два одинаковых кольца-измерителя переменного диаметра, соединенных между собой тремя стойками с разъемными соединениями с зонами временной фиксации нитей при пробном позиционировании створок АК. Актуальной задачей являлось изучение применения устройства в эксперименте.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: оценка возможности и удобства клапаносохраняющего протезирования корня аорты с реимплантацией АК с применением разработанного устройства для позиционирования створок АК в эксперименте.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В качестве моделей были использованы 10 трупных свиных сердец. Для реимплантации АК применялась стандартная техника операции Дэвида. После измерения параметров корня аорты, иссечения синусов Вальсальвы, выделения створок АК на комиссурах, проксимальной фиксации протеза аорты осуществлялось позиционирование створок для достижения максимальной площади коаптации и оптимального положения точки коаптации. Выполнялась статическая гидравлическая проба, при ее удовлетворительном результате фиксировались створки к стенке протеза.</p></sec><sec><title>Результаты</title><p>Результаты. При исходных измерениях медианы (Ме) межквартильные интервалы (Q1; Q3) диаметров синотубулярного соединения и фиброзного кольца (ФК) АК составили 21 (19; 21,3) и 20 (19; 21) мм соответственно. Статическая гидравлическая проба была неудовлетворительной в двух случаях: по причине неравномерного пролапса створок и из-за дефекта коаптации. Мы отметили неплотную фиксацию проксимального кольца в области ФК АК, сложности с перемещением раздвижных стоек и фиксацией нитей.</p></sec><sec><title>Заключение</title><p>Заключение. В эксперименте изучено устройство для позиционирования створок АК при операции Дэвида. Стандартизация данного вида вмешательств позволит улучшить результаты, повысить воспроизводимость и увеличить число выполняемых операций. Направлениями дальнейшей работы являются совершенствование крепления устройства в области ФК АК, ряд конструктивных доработок, а также улучшение возможностей выполнений точных измерений параметров корня аорты.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Valve-sparing aortic root replacement with aortic valve (AV) reimplantation (David procedure) is associated with low risks of thromboembolic and infectious complications. Its negative features are prolonged duration, risks of hemorrhage, and operator-dependence. To increase the speed of performance, improve reproducibility and reduce operator-dependence we have developed a device for intraoperative positioning of AV cusps. It consists of 2 identical rings-measuring devices of variable diameter, connected with each other by three struts with detachable connections with zones of temporary anchoring of sutures during the test positioning of cusps. The actual task was to study the application of the device in the experiment. Aim: To evaluate the possibility and convenience of valve-sparing aortic root replacement with AV reimplantation using the developed device for positioning of AV cusps in experiment.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. 10 cadaveric porcine hearts were used as models. The standard David technique was used for AV reimplantation. After measurement of aortic root parameters, dissection of the sinuses of Valsalva, isolation of the AV cusps with the commissures, proximal anchoring of the aortic graft, positioning of the cusps was performed to achieve the maximum area of coaptation and optimal position of the coaptation point. A static hydraulic test was performed and if it was satisfactory, the cusps were sutured to the inner side of the graft wall.</p></sec><sec><title>Results</title><p>Results. At baseline measurements, the medians (Q1; Q3) of sinotubular junction and aortic ring diameters were 21 (19; 21.3) and 20 (19; 21) mm, respectively. The static hydraulic test was unsatisfactory in two cases: due to asymmetric cusp prolapse and a coaptation defect. We noted loose anchoring of the proximal annulus in the area of aortic ring, difficulties in moving the sliding struts and anchoring of the sutures.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study assessed the device for positioning of AV cusps during David procedure. Standardization of this surgery type will improve the results, increase reproducibility and the number of performed operations. The areas of further work are the improvement of the device anchoring in the area of aortic annulus, some constructive modifications, as well as the improvement of the possibility to perform accurate measurements of the aortic root parameters.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма</kwd><kwd>грудная аорта</kwd><kwd>аортальный клапан</kwd><kwd>воспроизводимость результатов</kwd><kwd>клапаносохраняющее протезирование</kwd><kwd>реимплантация</kwd><kwd>свинья</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aneurysm</kwd><kwd>thoracic aorta</kwd><kwd>aortic valve</kwd><kwd>reproducibility of results</kwd><kwd>valve-sparing replacement</kwd><kwd>swine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках исполнения плановой темы государственного задания «Разработка устройства для клапаносохраняющей коррекции аортальной недостаточности», номер ЕГИСУ 123021000152-9.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the implementation of the planned topic of the state assignment “Development of a device for valve-preserving correction of aortic insufficiency”, EGISU number 123021000152-9.</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">David T.E., Feindel C.M.
