Оценка отдаленных результатов с акцентом на гемодинамические особенности аортального ксеноперикардиального бескаркасного протеза серии “БиоЛАБ КБ/А”.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. С 2007 по 2014гг было имплантировано 57 бескаркасных ксеноперикардиальных протезов серии “БиоЛАБ-КБ/А”. Средний возраст прооперированных составил 70±4 (от 49 до 80 лет), 6 пациентов моложе 65 лет. Средний период отдаленного наблюдения 8 лет (от 4 до 11 лет). Средний возраст пациентов на момент обследования 79 (70-89) лет.</p></sec><sec><title>Результаты</title><p>Результаты. Отдаленная выживаемость 73,82±7,99% — через 5 лет и 51,01±11,23% через 10 лет. Четыре пациента были реоперированы в отдаленном периоде в связи с дисфункцией биопротеза. Свобода от реопераций, связанных с инфекционным эндокардитом через год 95,1±2,4%, три года — 92,65±4,1%, пять — 89,1±5,2% и семь лет — 89,1±5,2%. Свобода от дисфункции биопротеза по причине структурной дегенерации составила 9,58±1,83 лет.</p></sec><sec><title>Заключение</title><p>Заключение. Мы считаем возможным использовать бескаркасный ксеноперикардиальный протез “БиоЛАБ КБ/А” при протезировании аортального клапана у пожилых пациентов, особенно, с узким корнем аорты. Однако использование технически более сложной методики во имя достижения большего геометрического отверстия неоправданно. Развитие значимой регургитации уже к 7 году после операции на больших размерах протезов приводит к необходимости решать вопрос о повторной операции, но уже у пациентов более старшего возраста и с наличием целого ряда сопутствующей патологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate long-term results of using xenogenic pericardial stentless prosthesis BioLAB KB/A.</p></sec><sec><title>Material and methods</title><p>Material and methods. From 2007 to 2014, 57 xenogenic pericardial stentless prostheses BioLAB KB/A were implanted. The mean age of operated patients was 70±4 (49-80 years of age); 6 patients were younger than 65 years old. The mean follow-up period was 8 years (4-11 years). The mean age of patients at the time of examination was 79 (70-89) years.</p></sec><sec><title>Results</title><p>Results. Five- and ten-year survival rates were 73,82±7,99% and 51,01±11,23%, respectively. Four patients underwent long-term reoperation due to bioprosthetic valve dysfunction. Freedom from reoperation associated with infective endocarditis after a year was 95,1±2,4%, three years — 92,65±4,1%, five years — 89,1±5,2%, and seven years — 89,1±5,2%. Freedom from prosthetic valve dysfunction due to structural degeneration was 9,58±1,83 years.</p></sec><sec><title>Conclusion</title><p>Conclusion. We consider it possible to use the xenogenic pericardial stentless prostheses BioLAB KB/A for aortic valve replacement in elderly patients, especially with a narrow aortic root. However, using a technically more complex technique for a larger geometric opening is not justified. Significant regurgitation at 7 years after surgery requires considering reoperation, but already in older patients and with a number of comorbidities.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бескаркасный ксеноперикардиальный протез</kwd><kwd>биопротезирование</kwd><kwd>аортальный клапан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>xenogenic pericardial stentless prostheses</kwd><kwd>bioprosthetics</kwd><kwd>aortic valve</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">Bakhtiary F, Schiemann M, Dzemali O, et al.
