The examination was carried out: electrocardiography; multislice computed tomography pulmonary angiography; echocardiography (EchoCG); transesophageal EchoCG; magnetic resonance imaging of the heart with contrast; screening for coagulopathy.</p><p><bold>Results</bold>. Based on clinical data, medical history, laboratory, instrumental diagnostic, we have put the diagnosis: Myxoma of the right atrium. Patent foramen ovale. Thrombophilia of mixed origin: hereditary – heterozygous mutation of the prothrombin gene (factor 2), acquired – hyperhomocysteinemia. Postthrombotic deep vein disease of the left lower limb. Recurrent pulmonary embolism (last relapse dated October 19, 2022). CTEPH functional class III (World Health Organization), moderate risk. Congestive heart failure with reduced right ventricular ejection fraction, functional class III (by the New York Heart Association). Relative tricuspid valve regurgitation grade 3. The patient underwent surgery: thromboendarterectomy from the right pulmonary artery under conditions of circulatory arrest and deep hypothermia, removal of a right atrium myxoma under conditions of artificial circulation and blood cold cardioplegia: tricuspid valve plasty according to De Vega. After surgery patient’s condition was significantly improved.</p><p><bold>Conclusion.</bold> The features of diagnosis and treatment of a patient suffering from CTEPH and cardiac myxoma are outlined. Surgery: Pulmonary thrombectomy and cardiac myxoma removal may improve the patient’s condition with CTEPH and left atrial myxoma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель работы</bold> – представление клинического случая молодого пациента с хронической тромбоэмболической легочной гипертензией (ХТЭЛГ) с миксомой сердца и тромбофилией смешанного генеза, которому проведено оперативное лечение.</p><p><bold>Материалы и методы</bold>. Больной З., 24 года, поступил в отделение кардиологии с жалобами на кашель с выделением мокроты, возникающий при физической нагрузке, в том числе с прожилками крови, одышку при небольшой физической нагрузке, пастозность голеней и стоп, общую слабость и головокружение. проведено комплексное обследование больного З.: электрокардиография, мультиспиральная компьютерная томография с контрастированием легочной артерии, эхокардиография (ЭхоКГ), чреспищеводная ЭхоКГ, магнитно-резонансная томография сердца с контрастированием, скрининг на коагулопатии.</p><p><bold>Результаты</bold>. На основании данных клинической картины, анамнеза и результатов лабораторно-инструментальных методов исследований установлен диагноз: «Миксома правого предсердия. Открытое овальное окно. Тромбофилия смешанного генеза: наследственная – гетерозиготная мутация гена протромбина (фактора 2), приобретенная – гипергомоцистеинемия. посттромботическая болезнь глубоких вен левой нижней конечности. Рецидивирующая тромбоэмболия легочной артерии (последний рецидив от 19.10.2022 г.). ХТЭЛГ III функциональный класс (по классификации Всемирной организации здравоохранения), умеренный риск. Хроническая сердечная недостаточность со сниженной фракцией выброса правого желудочка, III функциональный класс (по классификации Нью-Йоркской кардиологической ассоциации). Относительная недостаточность трикуспидального клапана 3-й степени». пациенту выполнено оперативное вмешательство: тромбэндартерэктомия из правой легочной артерии в условиях циркуляторного ареста и глубокой гипотермии, удаление миксомы правого предсердия в условиях искусственного кровообращения и кровяной холодовой кардиоплегии: пластика трикуспидального клапана по Де Вега (N. DeVega).</p><p><bold>Заключение.</bold> Изложены особенности диагностики, лечения пациента, страдающего ХТЭЛГ и миксомой сердца. проведенная тромбэктомия из легочной артерии и удаление миксомы сердца могут улучшить состояние пациента с ХТЭЛГ и миксомой левого предсердия.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pulmonary hypertension</kwd><kwd>chronic thromboembolic pulmonary hypertension</kwd><kwd>myxoma</kwd><kwd>thromboembolism</kwd><kwd>thrombophilia</kwd><kwd>transesophageal echocardiography</kwd><kwd>thrombolytic therapy</kwd><kwd>multispiral computed tomography</kwd><kwd>angiography</kwd><kwd>heterozygous mutation of the prothrombin gene (factor 2)</kwd><kwd>hyperhomocysteinemia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>легочная гипертензия</kwd><kwd>хроническая тромбоэмболическая легочная гипертензия</kwd><kwd>миксома</kwd><kwd>тромбоэмболия</kwd><kwd>тромбофилия</kwd><kwd>чреспищеводная эхокардиография</kwd><kwd>тромболитическая терапия</kwd><kwd>мультиспиральная компьютерная томография</kwd><kwd>ангиография</kwd><kwd>гетерозиготная мутация гена протромбина (фактора 2)</kwd><kwd>гипергомоцистеинемия</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">Chazova I.E., Martynyuk T.V., Valieva Z.S. et al.
