Лечение КМП при синдроме Нунан проводится в соответствии с клиническими рекомендациями по лечению хронической сердечной недостаточности (ХСН) и КМП. Хирургическое лечение прогрессирующей ХСН на фоне обструкции выводных трактов желудочков и митральной недостаточности может быть методом выбора. В обзоре представлен наш опыт проведения септальной миоэктомии (СМ) у детей с обструктивной формой ГКМП в структуре синдрома Нунан.</p><p>Цель работы — определить эффективность СМ ГКМП у детей с синдромом Нунан.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Применены клинические (сбор семейного анамнеза, осмотр пациента), лабораторные (определение уровня натрийуретического пептида — NT-proBNP), инструментальные (эхокардиография), электрокардиография (ЭКГ), суточное мониторирование ЭКГ, рентгенография органов грудной клетки) и молекулярно-генетические методы с использованием технологии массового параллельного секвенирования (NGS) и прямого автоматического секвенирования по Сэнгеру. Показания для СМ были определены в соответствии с рекомендациями по диагностике и лечению ГКМП у взрослых.</p></sec><sec><title>Результаты</title><p>Результаты. Из 48 пациентов с синдромом Нунан СМ была проведена 7 детям с синдромом Нунан и 1 — с синдромом Нунан с множественными лентиго (синдром LEOPARD), из них 2 пациентам потребовалось устранение обструкции выходных трактов обоих желудочков с последующей пластикой выводного отдела правого желудочка и клапана лёгочной артерии. Сопутствующие хирургические манипуляции включали протезирование аортального (n = 1) и митрального клапанов (n = 2), имплантацию электрокардиостимулятора (n = 1) в раннем послеоперационном периоде. Через год у всех больных зафиксировано уменьшение содержания в крови NT-proBNP более чем в 4 раза со среднего значения 16 198 пг/мл до 3865 пг/мл, значимое улучшение самочувствия, купирование одышки, повышение толерантности к физическим нагрузкам, улучшение показателей физического (вес, рост) и речевого развития. При анализе параметров эхокардиографии через 1 год после СМ отмечена нормализация размеров обоих предсердий у 4 детей, уменьшение выраженности изолированной дилатации левого предсердия — у 2. Формирования повторной обструкции не отмечено.</p></sec><sec><title>Заключение</title><p>Заключение. ГКМП может быть в структуре наследственных синдромов, таких как синдром Нунан. СМ может быть применена у детей с синдромом Нунан в случае прогрессирующей ХСН вследствие обструктивной формы ГКМП.</p></sec><sec><title>Участие авторов</title><p>Участие авторов:Гандаева Л.А., Басаргина Е.Н. — концепция и дизайн исследования;Гандаева Л.А., Басаргина Е.Н., Савостьянов К.В. — сбор и обработка материала;Гандаева Л.А. — написание текста;Басаргина Е.Н., Савостьянов К.В., Кондакова О.Б. — редактирование.Все соавторы — Утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Финансирование</title><p>Финансирование.

The treatment of cardiomyopathy patients with Noonan syndrome is carried out according to the cli­nical recommendations for the treatment of chronic heart failure (CHF) and cardiomyopathy. Surgical treatment of progressive nature of heart failure with left ventricular outflow tract obstruction and mitral regurgitation can be one of the possible methods. The review presents our experience with septal myectomy (SM) in children suffered from hypertrophic obstructive cardiomyopathy with Noonan syndrome.</p><sec><title>Objective</title><p>Objective. To assess the efficiency of septal myectomy in children suffered from hypertrophic obstructive cardiomyopathy with Noonan syndrome.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Clinical examination (family history, patient examination), lab tests (NT-proBNP level), echocardiography, electrocardiography, Holter monitoring, Chest X-rays and molecular genetic methods using mass parallel sequencing (NGS) and direct automatic Sanger sequencing. The indications for the SM were determined according to the clinical guidelines for the diagnostic and treatment of hypertrophic cardiomyopathy.</p></sec><sec><title>Results</title><p>Results. 7 patients out of 48 with Noonan syndrome underwent SM and 1 with Noonan syndrome with multiple lentigo (LEOPARD). Two of them required the removal of obstruction of the outflow tracts of both ventricles, followed by plastic removal of the right ventricle and pulmonary artery valve. Related surgical interventions included aortic (n = 1) and mitral valves (n = 2), permanent pacemaker (n = 1) in the early postoperative period. After a year, all children recorded a decline of NT-proBNP from the average of 16,198 to 3,865 pg/ml, a significant improvement in health, disappearance of shortness of breath, increased physical activity tolerance, improved physical (weight, growth) and speech development. When assessing the dynamics of the Echo parameters 1 year after the SM, normalization of the size of both atria in 4 cases, reduction of severity of isolated dilation of the left atrium in 2 cases was noted. No cases of repeated obstruction have been reported.</p></sec><sec><title>Conclusion</title><p>Conclusion. Hypertrophic cardiomyopathy (HCM) can be in structure of hereditary syndromes such as Noonan syndrome. Septal myectomy (SM) can now be used in the case of progressive nature of heart failure with left ventricular outflow tract obstruction in children with Noonan syndrome.</p></sec><sec><title>Contribution</title><p>Contribution:Gandaeva L.A., Basargina E.N. — concept and design of the study;Gandaeva L.A., Basargina E.N., Savostyanov K.V. — collection and processing of material;Gandaeva L.A. — statistical processing, text writing;Basargina E.N., Kondakova O.B., Savostyanov K.V. — text editing.Аll co-authors — аpproval of the final version of the article, responsibility for the integrity of all parts of the article.</p></sec><sec><title>Acknowledgement</title><p>Acknowledgement.
