Неспецифические клинические синдромы, обусловленные наличием , локализацией или структурными особенностям и опухоли, включающие системные проявления, застойную сердечную недостаточность, вызванную обструктивными внутрисердечными нарушениями или эмболии в сосуды большого и малого круга кровообращения обосновывают выполнение диагностических методов визуализации сердца. Информативным неинвазивным методом диагностики является эхокардиография, выполнение которой в двух случаях наблюдения позволило выявить миксомы сердца.</p></abstract><trans-abstract xml:lang="en"><p>Absence of characteristic signs leads to late diagnosis of myxoma of the heart, complicated by congestive heart failure, embolism in various vascular regions, cardiac arrhythmias, sudden cardiac death. Nonspecific clinical syndromes due to the presence, localization or structural features of the tumor including systemic manifestations, congestive heart failure caused by obstructive intracardiac disorders or embolism in the vessels of the systemic and pulmonary circulation justify the performance of diagnostic methods of heart visualization. An informative noninvasive method of diagnosis is echocardiography, which, in two cases of observation, revealed myxoma of the heart.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миксома сердца</kwd><kwd>диагностические методы</kwd><kwd>клинические симптомы</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac myxoma</kwd><kwd>diagnostic methods</kwd><kwd>clinical symptoms</kwd><kwd>echocardiography</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">Lamba G., Frishman W.H.
