При преимущественно левожелудочковом варианте нарушения насосной функции сердца применение изолированного левожелудочкового обхода (ЛЖО), особенно при наличии высокой легочной гипертензии (ЛГ), представляется более физиологическим методом краткосрочной МПК.</p><sec><title>Цель исследования</title><p>Цель исследования: представление результатов серии клинических наблюдений применения чрескожного левожелудочкового обхода (чЛЖО) перед ТС у потенциальных реципиентов с преимущественно левожелудочковой дисфункцией и сопутствующей высокой ЛГ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включили трех потенциальных реципиентов сердца с преимущественно левожелудочковым вариантом СН и высокой предтрансплантационной ЛГ (ЛСС 4,7–6,6 ед. Вуда), нуждавшихся в МПК в связи с прогрессированием гемодинамических нарушений. Для чЛЖО по схеме «левое предсердие – бедренная артерия» использовали стандартную венозную ЭКМО-канюлю (26 F), проведенную из трансфеморального доступа через межпредсердную перегородку в полость левого предсердия. Паракорпоральный центрифужный насос обеспечивал нагнетание крови через стандартную артериальную ЭКМО-канюлю (15 F).</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. чЛЖО обеспечил эффективную разгрузку левых отделов сердца (снижение ЗДЛА с 27–32 до 15–20 мм рт. ст.), снижение предтрансплантационной ЛГ (снижение ДЛАср. с 45–53 до 28–33 мм рт. ст.) и улучшение системной гемодинамики (увеличение СИ с 1,8–1,9 до 2,1–2,6 л/мин/м2 и АДср. с 56–59 до 70–75 мм рт. ст.), что создало предпосылки для последующего успешного выполнения ТС. На фоне чЛЖО ТПГ снизился с 15–25 до 13–15 мм рт. ст., ЛСС – с 4,7–6,6 до 2,7–3,4 ед. Вуда. Объемная скорость чЛЖО составила 2,9–3,8 л/мин, или 1,38–1,83 л/мин/м2 при частоте оборотов насоса 4700–7100 в мин. Продолжительность чЛЖО составила от 4 (n = 1) до 7 (n = 2) суток. Всем пациентам была выполнена успешная ТС.</p></sec><sec><title>Заключение</title><p>Заключение. чЛЖО является высокоэффективным методом краткосрочной МПК у потенциальных реципиентов с преимущественным нарушением насосной функции левого желудочка и сопутствующей ЛГ, приводя к ее быстрому регрессу на фоне объемной разгрузки левых отделов сердца. Данный метод краткосрочной МПК может быть успешно реализован с использованием стандартных ЭКМО-канюль и центрифужного насоса любой модификации, не требуя дополнительного специального оборудования.</p></sec></abstract><trans-abstract xml:lang="en"><p>Federation In certain categories of patients with end-stage heart failure (HF), short-term mechanical circulatory support (MSC) is successfully used as a mechanical «bridge» to heart transplantation (HTx). In predominantly left-ventricular (LV) dysfunction, the use of isolated coronary artery bypass, especially amidst high pulmonary hypertension (PH), seems to be a more physiological method of short-term MSC.</p><sec><title>Objective</title><p>Objective: to present the results of a series of clinical cases of the use of percutaneous left ventricular assist device (pLVAD) before HTx in potential recipients with predominantly LV dysfunction and concomitant high PH.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Three potential heart recipients with predominantly left-sided HF and high pre-transplant PH (pulmonary vascular resistance, PVR, 4.7–6.6 Wood units) who required MSC due to progression of hemodynamic disorders were included in the study. A standard venous extracorporeal membrane oxygenation (ECMO) cannula (26 F) was used for percutaneous left atrial-femoral artery (LA–FA) bypass. The cannula was passed from the transfemoral route through the interatrial septum into the left atrial cavity. A paracorporeal centrifugal pump provided blood injection through a standard arterial ECMO cannula (15 F).</p></sec><sec><title>Results</title><p>Results. pLVAD unloaded the left ventricle effectively (PCWP reduced from 27–32 to 15–20 mmHg), reduced pre-transplant PH (mean pulmonary artery pressure (mPAP) reduced from 45–53 to 28–33 mmHg) and improved systemic hemodynamics (cardiac index (CI) increased from 1.8–1.9 to 2.1–2.6 l/min/m2 and mean arterial pressure (mAP) from 56–59 to 70–75 mmHg). All these created the prerequisites for subsequent successful HTx. Against the background of pLVAD, transpulmonary pressure gradient (TPG) decreased from 15–25 to 13–15 mmHg, and PVR decreased from 4.7–6.6 to 2.7–3.4 Wood units. pLVAD flow rate was 2.9–3.8 L/min or 1.38–1.83 L/min/m2 at 4700–7100 rpm. pLVAD duration ranged from 4 (n = 1) to 7 (n = 2) days. All patients underwent successful HTx.</p></sec><sec><title>Conclusion</title><p>Conclusion. pLVAD is a highly effective method of short-term MSC in potential recipients with predominantly LV dysfunction and concomitant high PH, leading to rapid regression of the dysfunction against the background of left ventricular unloading. This short-term MSC technique can be successfully realized using standard ECMO cannulas and centrifugal pumps of any modification, without requiring additional special equipment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трансплантация сердца</kwd><kwd>механическая поддержка кровообращения</kwd><kwd>легочная гипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart transplantation</kwd><kwd>mechanical circulatory support</kwd><kwd>pulmonary hypertension</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">Brown LJ, Estep JD.
