На сегодняшний день единой тактики лечения пациентов с аномально локализованными коронарными артериями по типу «мышечного мостика» не существует. Имеются противоречивые сведения о пользе стентирования коронарных артерий в связи с частыми поломками стентов или перфораций туннелированного сосуда. По поводу данной проблемы ни одного крупного рандомизированного исследования не проводилось. В этой связи целью настоящей работы являлась оценка прочностных характеристик стентов в воссозданной нами модели мышечного моста.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. На разработанной нами оригинальной модели миокардиального моста определили предел прочности коронарных стентов в условиях, максимально приближенных к физиологическим. Стенты помещались в трубку из политетрафторэтилена, частота колебаний, имитирующих мост, была выставлена 250 ударов в минуту. Результаты опыта фиксировались на USB-камеру каждые 30 минут с целью регистрации механических дефектов стента.</p><p>Результаты и их обсуждение. В стенте, состоящем из ячеек, соединяющихся с помощью V-образных соединений, отмечались первые признаки деформации балок уже на десятые сутки, полная поломка произошла на семнадцатые сутки от момента имплантации. Стент без V-образных соединений при наблюдении в течение двух месяцев сохранял механическую целостность.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, гипотеза о нецелесообразности имплантации стентов в коронарную артерию с мышечным мостом не совсем корректна. Принимая во внимание полученные нами данные, можно предположить, что структура, конструкция, форма и состав стентов предопределяют возможность его имплантации в коронарную артерию с мышечным мостом, но требуют персонализационного подхода для каждого конкретного пациента. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Presently there is no unified tactics to treat patients with aberrantly localized coronary arteries of “muscular bridge” type. There are controversial data regarding the benefit of coronary artery stenting due to often stent breakage or perforation of tunneled vessel. There are no major randomized studies regarding this issue. In this regard the goal of this research was to assess strength characteristics of stents in the model of muscular growth that we restored.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The originally developed model enabled to determine the strength limit of coronary stents under conditions that are maximum close to the physiological ones. The stents were placed into a polytetrafluoroethylene tube, the bridge-imitating oscillation frequency was configured to 250 beats per minute. The results of the experiment were recorded on USB-camera each 30 minutes in order to register mechanical defects of the stent.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The stent consisting of cells that are joined with V-shaped connections, showed first signs of strut deformity on the 10th day. Complete breakage happened on the 17th day after implantation. After 2 months observation the stent preserved mechanical firmness without V-shaped connections.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, it is not quite correct to support the hypothesis on infeasibility of stent implantation into the coronary artery with a muscular bridge. Taking into consideration the findings it is possible to suppose that the structure, design, form and content of stents predetermine the possibility to implant it into coronary artery with muscular bridge, but require individual approach to every particular patient. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мышечные мосты</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>коронарные стенты</kwd><kwd>биологические модели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardial bridge</kwd><kwd>ischemic heart disease</kwd><kwd>coronary stents</kwd><kwd>biological models</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">Ishikawa Y., Kawawa Y., Kohda E, Shimada K., Ishii T.
