С февраля 2009 г. по июль 2016 г. протезирование аортального клапана с использованием аллографтов выполнено у 102 пациентов. Функцию аллографта и ЛЖ сердца оценивали в послеоперационном периоде на 7–10-е сутки, в отдаленном послеоперационном периоде – через 3, 6 мес., 1, 2, 3 года. Имплантированные аллографты в аортальной позиции показали удовлетворительные гемодинамические показатели как в раннем, так и в позднем послеоперационном периоде. При этом показатели площади эффективного отверстия не изменились на всех размерах аллографтов. В то же время отмечалось достоверное уменьшение максимальной скорости на аортальных аллографтах, что привело к субоптимальным показателям систолического и среднего градиентов в раннем послеоперационном периоде, уменьшившимся до показателей нормы для нативного аортального клапана в промежутке времени от 3 мес. до 2 лет. В первые 3 мес. после имплантации аллографтов в аортальную позицию достоверно происходило ремоделирование ЛЖ сердца, приводившее к уменьшению конечно-диастолического и конечно-систолического размеров и объемов ЛЖ, восстановлению его фракции выброса, уменьшению толщины миокарда задней стенки ЛЖ как во время систолы, так и во время диастолы. В то же время за исследуемый период наблюдалось достоверное уменьшение толщины миокарда межжелудочковой перегородки во время диастолы. Причем данные изменения были достоверны в сроки от 6 мес. до 1 года и от 2 до 3 лет после хирургического вмешательства. Произошедшее ремоделирование ЛЖ привело к достоверному улучшению качества жизни пациентов, оцененное с помощью опросника MLHFQ, в сроки до 3 мес. после имплантации. Таким образом, использование аллографтов в аортальной позиции позволяет в значительной степени приблизиться к параметрам функционирования нативного клапана как в раннем, так и в отдаленном (3 года) периоде. </p></abstract><trans-abstract xml:lang="en"><p>The study was aimed at learning the left ventricle remodeling in patients after aortic allograft implantation during the long-term follow-up. From February 2009 to July 2016 the aortic valve replacement with allografts was performed in 102 patients. Hemodynamic parameters of implanted allografts and left ventricle function were assessed for 7–10 days postoperatively and at long-term follow-up visits: in 3 and 6 months, 1, 2 and 3 years. Implanted aortic allografts are characterized by satisfactory hemodynamic parameters in early and late postoperative periods. The effective orifice area of implanted valves did not change in any of the implanted allografts during the period under study. At the same time, there was a significant reduction in the maximum speed across the aortic valve, resulting in suboptimal systolic and mean gradients in the early postoperative period, which declined to normal values from 3 months to 2 years postoperatively. 3 During the first 3 months after the aortic allograft implantation there was a statistically significant left ventricle remodeling, which led to a decrease in end-diastolic and end-systolic left ventricle sizes and volumes, as well as to the restoration of the left ventricle ejection fraction. During the same period there was a reduction in the left ventricle myocardium thickness both during systole and diastole. At the same time, there was a significant reduction in the thickness of the interventricular septum myocardium during diastole. The changes described were statistically significant during the following periods: from 6 months to 1 year and from 2 to 3 years postoperatively. Left ventricle remodeling resulted in a significant improvement in the patients’ quality of life up to 3 months postoperatively, assessed using a MLHFQ questionnaire. During the first 3 months after aortic allograft implantation, the left ventricle was remodeled, which resulted in a decrease in end-diastolic and end-systolic left ventricle sizes, as well as in an increase in the left ventricle contractility. The life quality of patients after allograft implantation significantly improves during the first 3 months. Aortic allografts in the aortic position generally resemble the functioning of the native aortic valve during early and long-term (3-years) follow-up. During first three months after aortic allograft implantation we observed the left ventricle remodeling, which led to a decrease in the left ventricle end-diastolic and end-systolic sizes, as well as to a decrease in the end-diastolic and end-systolic left ventricle volume, and to an increase in the left ventricle contractility. The quality of life in patients after aortic allograft implantation significantly improved during first three months postoperatively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аллографты</kwd><kwd>гемодинамические показатели</kwd><kwd>ремоделирование левого желудочка сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>allografts</kwd><kwd>hemodynamic parameters</kwd><kwd>left ventricle remodeling</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">Prognostic implications of echocardiographically determined left ventricular mass in the Framingham heart study / D.
