Построены компьютерная и физическая модели дискового протеза аортального клапана. Выполнен анализ поля скоростей и давлений при прямом и обратном токе крови, показавший преимущества двухстворчатых протезов. Достоинством использованного подхода является возможность детального описания движения крови с выявлением зон турбулентности и разрежения для различных вариантов конструкции, включая размер, кривизну и предельный угол открытия створок. Это позволяет минимизировать гидравлическое сопротивление, тромбообразование и гемолиз, сохраняя высокую надежность закрытия клапана. Обсуждается возможность проектирования протеза с целью повышения адекватности его клапанной функции путем реализации закручивания потока крови.</p></abstract><trans-abstract xml:lang="en"><p>The valve functions of heart (in norm and pathological state) and hemodynamic characteristics of mechanical prosthetic cardiac valves influencing hemolysis and blood coagulation have been investigated. The computer and physical models of the disc cardiac valve implant have been constructed. The analysis of blood velocity and pressure at direct and inverse blood flows has shown better characteristics of butterfly valves. An advantage of this approach is in thorough description of blood flow assisting in determination of turbulence and depression zones for different size, curvature and ultimate opening angle of the leaves. This minimises hydraulic resistance, thrombus formation and hemolysis thus preserving high reliability of valve closing. A design of the valve prosthesis aimed at improving valve functions by swirling the blood flow is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клапанная функция сердца</kwd><kwd>дисковый протез клапана</kwd><kwd>биосовместимость</kwd><kwd>гемодинамика</kwd><kwd>регургитация</kwd><kwd>гемолиз</kwd><kwd>тромбообразование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>VALVE FUNCTION OF HEART</kwd><kwd>DISC CARDIAC VALVE PROSTHESIS</kwd><kwd>BIOCOMPATIBILITY</kwd><kwd>HEMODYNAMICS</kwd><kwd>REGURGITATION</kwd><kwd>HEMOLYSIS</kwd><kwd>THROMBUS FORMATION</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">Хирургия сердца. // Под ред.
