Оценить распространенность поражения левого желудочка и особенности бивентрикулярного фенотипа аритмогенной кардиомиопатии у пациентов с патогенными мутациями в генах PKP2 и DSP.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Трем неродственным пробандам проведено комплексное молекулярно-генетическое и клинико-инструментальное обследование, включавшее ЭКГ в 12 отведениях, суточное мониторирование ЭКГ, трансторакальную эхокардиографию и магнитно-резонансную томографию сердца с отсроченным контрастным усилением.</p></sec><sec><title>Результаты</title><p>Результаты. Результаты клинических наблюдений показали, что у трёх исследуемых пациентов с аритмогенной кардиомиопатией было обнаружено различной степени вовлечение левого желудочка, которое характеризовалось фиброзной или фиброзно-жировой инфильтрацией миокарда, а также региональной или глобальной систолической дисфункцией различной степени выраженности. У пациентов выявлены патогенные мутации c.1912C &gt; T (p.Gln638*, rs397517012, rs397517012); c.1237C &gt; T (p.Arg413*, rs372827156) в гене PKP2 и новый вероятно патогенный вариант мутации в гене DSP в виде делеции c.3494delА. Было выявлено, что мутация в гене DSP была ассоциирована с более выраженной систолической дисфункцией и бо́льшим процентом фиброзного замещения миокарда левого желудочка по сравнению с носителями мутаций в гене PKP2. У всех пациентов наблюдались жизнеугрожающие желудочковые аритмии с необходимостью имплантации кардиовертера-дефибриллятора.</p></sec><sec><title>Заключение</title><p>Заключение. Наши клинические наблюдения показали, что в серии случаев трёх пациентов с бивентрикулярным фенотипом аритмогенной кардиомиопатии выявление мутации в гене DSP было ассоциировано с более выраженной систолической дисфункцией и бо́льшим процентом фиброзного замещения миокарда ЛЖ по сравнению с носителями мутаций в гене PKP2.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the prevalence of the left ventricle involvement and the features of the biventricular phenotype of arrhythmogenic cardiomyopathy in patients with pathogenic mutations in the PKP2 and DSP genes.</p></sec><sec><title>Material and methods</title><p>Material and methods. Three unrelated probands underwent a comprehensive molecular-genetic, clinical and instrumental examination, which included a 12-lead ECG, 24-hour ECG monitoring, transthoracic echocardiography, and cardiac magnetic resonance imaging with late gadolinium enhancement.</p></sec><sec><title>Results</title><p>Results. The results of our clinical observations showed that in three studied patients with arrhythmogenic cardiomyopathy left ventricle involvement of various degree was found. The left ventricle damage was characterized by fibrous or fibro-fatty infiltration of the myocardium, as well as regional or global systolic dysfunction of different severity. The patients had pathogenic mutations c.1912C &gt; T (p.Gln638*, rs397517012, rs397517012); c.1237C &gt; T (p.Arg413*, rs372827156) in the PKP2 gene and a new probably pathogenic variant in the form of a c.3494delA deletion in the DSP gene. It was found that the mutation in the DSP gene was associated with a more pronounced systolic dysfunction and a greater percentage of fibrous replacement of the left ventricular myocardium compared with carriers of mutations in the PKP2 gene. All patients had life-threatening ventricular arrhythmias with the need for implantation of a cardioverter-defibrillator.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our clinical observations have shown that in patients with biventricular arrhythmogenic cardiomyopathy, the detection of a mutation in the DSP gene is associated with a more pronounced systolic dysfunction and a higher percentage of fibrous replacement of the left ventricle myocardium compared with carriers of mutations in the PKP2 gene.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аритмогенная кардиомиопатия</kwd><kwd>МРТ-диагностика</kwd><kwd>мутация</kwd><kwd>ген PKP2</kwd><kwd>ген DSP</kwd><kwd>кардиовертер-дефибриллятор</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arrhythmogenic cardiomyopathy</kwd><kwd>MRI</kwd><kwd>mutation</kwd><kwd>PKP2 gene</kwd><kwd>DSP gene</kwd><kwd>cardioverter-defibrillator</kwd><kwd>clinical case</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">Corrado D., Basso C., Judge D.P.
