Установлено, что наиболее часто (92,1 % наблюдений) ММ встречаются над передней межжелудочковой ветвью (ПМЖВ) левой венечной артерии. При этом в большинстве случаев (74,29 %) ММ располагались во втором сегменте ПМЖВ, реже (20 % случаев) – в третьем сегменте, крайне редко (5,71 %) – в первом сегменте артерии. Показаны особенности строения ММ в зависимости от типа кровоснабжения сердца. Высота ММ в сердцах с правовенечным типом кровоснабжения существенно превышает высоту ММ в сердцах со смешанным типом кровоснабжения, что косвенно указывает на бhtml5-dom-document-internal-entity2-243-endльшую вероятность развития кардиоваскулярной патологии в артериях под ММ в сердцах с правовенечным типом кровоснабжения. Выявлены три варианта отхождения первой перегородочной ветви от ПМЖВ: до ММ (64,29 % случаев), на уровне начала ММ (14,28 %) и от сегмента сосуда, расположенного под ММ (21,43 %). Описаны особенности хода подмостикового участка ПМЖВ артерии в миокарде межжелудочковой перегородки.</p></abstract><trans-abstract xml:lang="en"><p>The article presents data on the topographic and morphometric features of the myocardial bridges (MM) and the sections of the branches of the coronary arteries located under them, established by computed tomography (retrospectively) in the hearts of patients with cardiovascular pathology. It was found that the majority (92.1 % of cases) of MM occur over the anterior interventricular branch (LAD) of the left coronary artery. In most cases (74.29 %), MM was located in the second segment of the LAD, less often (20 % of cases) – in the third segment, extremely rarely (5.71 %) – in the first segment of the artery. The features of their structure depending on the dominance of the coronary circulation are shown. The height of MM in hearts with the right-dominant coronary circulation significantly exceeds the height of MM in hearts with the codominant coronary circulation, which indirectly indicates a greater probability of developing cardiovascular pathology in the arteries under MM in hearts with the right-dominant circulation. Three variants of the origin of the first septal branch from the LAD were identified: up to MM (64.29 % of cases), at the level of the beginning of MM (14.28 %) and from the segment of the vessel located under MM (21.43 %). The features of the passage of the segment of the LAD located under MM through the myocardium of the interventricular septum are described.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сердце</kwd><kwd>миокардиальные мостики</kwd><kwd>венечные артерии</kwd><kwd>компьютерная томография</kwd><kwd>человек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>human anatomy</kwd><kwd>heart</kwd><kwd>myocardial bridges</kwd><kwd>coronary arteries</kwd><kwd>computed tomography</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">Ташнік, М.
