A rare clinical case is presented: the detection of a tumor of the left atrium using high-tech endoscopic techniques, in particular a EuS-FnA. when studying the surgical material using immunohistochemistry and FISH hybridization, the final diagnosis sounded like intimal sarcoma. Diagnosis of intimal sarcoma is a complex clinical task, and difficulties in making a diagnosis delay the duration of treatment. Our experience demonstrates the modern role of endoscopy as a minimally invasive method of diagnosing intracardiac tumors.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> за последние 30 лет благодаря развитию эндоскопических технологий и появлению тонкоигольной пункции под контролем эндоскопической эндосонографии стала возможна диагностика с предварительной верификацией опухолей сердца, что, в свою очередь, является несомненным преимуществом в выявлении кардиальной патологии. В работе представлено редкое клиническое наблюдение: выявление опухоли левого предсердия при помощи высокотехнологичных эндоскопических методик, в частности тонкоигольной пункционной биопсии. При изучении операционного материала с использованием иммуногистохимического исследования и флуоресцентной <italic>in-situ</italic> гибридизации окончательный диагноз звучал как «саркома интимы легочных сосудов». Диагностика саркомы интимы легочных сосудов является сложной клинической задачей, а трудности в постановке диагноза увеличивают сроки лечения. Наш опыт демонстрирует современную роль эндоскопии как минимально инвазивного метода диагностики внутрисердечных опухолей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>intimal sarcoma</kwd><kwd>endoscopy</kwd><kwd>endoscopic ultrasound-guided fine-needle aspiration</kwd><kwd>endosonography</kwd><kwd>сardiac tumors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома интимы</kwd><kwd>эндоскопия</kwd><kwd>тонкоигольная пункция под контролем эндоскопического ультразвукового исследования</kwd><kwd>опухоль сердца</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
