Изучали пространственную конфигурацию фиброзного кольца и створчатого аппарата митрального клапана, пространственные и объемные показатели левого предсердия и левого желудочка. Обработку данных производили в среде SciLab 4.1.2 и экспортировали в систему проектирования CATIA 5, где полученные наборы кривых объединяли сначала в две цельные тонкостенные модели, а после сшивки поверхностей получали твердотельную модель с необходимыми толщинами стенок.</p></sec><sec><title>Результаты</title><p>Результаты: Все исследуемые показатели выявили достоверные различия (p&lt;0,001) при сравнении групп. При рестриктивном типе недостаточности увеличиваются размеры фиброзного кольца: межкомиссуральный диаметр на 22%, переднее-задний – на 13%, периметр – на 28%, площадь - на 79%. Конечный систолический и конечный диастолический объемы ЛЖ возрастают более чем в 2 раза, что сопряжено с большей сферичностью ЛЖ, чем в норме. Увеличение размеров ЛП в 1,5 раза также сочетается с изменением его геометрии в сторону сферы. Создана трехмерная компьютерная модель левых отделов сердца, измененных в результате ишемической митральной недостаточности. Данная модель может быть использована в задачах проектирования, анализа и прогнозирования работы медицинских устройств, предназначенных для данной позиции и/или реализована в виде полноразмерных макетов, тестовых систем и фантомов для целей разработок и обучения.</p></sec><sec><title>Заключение</title><p>Заключение: Исследование характеристик митрального клапана и левых отделов сердца методом трехмерной трансторакальной и чреспищеводной эхокардиографии обеспечивает получение исходного комплекса данных, необходимых для создания трехмерных компьютерных моделей данной анатомической области в норме и при различных патологических состояниях. Такие модели могут быть использованы при разработке конструкций имплантируемых устройств, предварительных испытаниях медицинских изделий, а также в обучающих целях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Comparative analysis of the acquired with EchoCG method parameters of the left chambers of the heart and of mitral valve in normal state and in restrictive type of failure with further building up three-dimensional models of these variants of the fibrous anulus geometry, and of the left atrium, left ventricle and its outgoing tract.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study was done using 3D transthoracal and transesophageal EchoCG on Philips iE33 (Philips Healthcare, USA) in 30 patients with unchanged mitral valve (n=15) and in ischemic mitral regurgitation (n=15). Spatial configuration of the anulus fibrosus was investigated, and mitral valve, spatial and volumetric parameters of the left atrium and left ventricle. Data was processed in SciLab 4.1.2 software and exported to CATIA 5 modelling system, where the acquired curves were combined to 2 solid thin-wall models, and after linking of the surfaces — to a hard-bodied model with required thickness of the walls.</p></sec><sec><title>Results</title><p>Results. All studied parameters revealed significant differences (p&lt;0,001) in groups comparison. In restrictive type of insufficiency, sizes of fibrous anulus increase: intercomissural diameter by 22%, front-back — by 13%, perimeter — by 28%, surface — by 79%. End systolic and diastolic volumes of the LV increase more than 2 times, which is related with more prominent sphericity of the LV, than normally. Increase of LA more than 1,5 times also combines with its geometry change towards sphere. Three dimensional computer model of the left heart chambers changed as a result of ischemic mitral failure, is created. The model can be implemented in creation, analysis and prediction of medical devices for the position and/or realized as the full-sized mockups, test systems and phantoms for development and education.</p></sec><sec><title>Conclusion</title><p>Conclusion. The investigation of mitral valve characteristics and of the left heart chambers by method of 3D transthoracal and transesophageal echocardiography makes it to obtain the baseline data necessary for creation of 3D computed models of the anatomic area normal and disordered. Such models can be implemented in the development of implanted devices constructions, preliminary tests of medical devices and in training.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>левые отделы сердца</kwd><kwd>трехмерные модели</kwd><kwd>транскатетерные клапаны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>left chambers of the heart</kwd><kwd>three-dimensional models</kwd><kwd>transcatheter valves.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российского научного фонда (грант 16-15-10315).</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">Cribier A, Durand E, Eltchaninoff H.
