Физиологическое накопление 123I-mIBG обеспечивает анатомическое количественное определение структур автономной нервной системы (АНС) с дискретными очагами симпатической активности (ОСА), расположенными в левом предсердии (ЛП), соответствующими основным ганглионарным сплетениям (ГС), которые ранее не могли быть визуализированы. Цель исследования. Визуализация очагов симпатической активности сердца у пациентов с пароксизмальной формой фибрилляцией предсердий (ФП) и оценка влияния радиочастотной абляции (РЧА) на ОСА в ЛП. Материалы и методы. Пятнадцати пациентам с пароксизмальной ФП была выполнена компьютерная томография (КТ) сердца и радионуклидная визуализация с помощью 123I-mIBG. Результаты исследования были совмещены с предварительно полученными изображениями КТ для создания подробной анатомической карты симпатической активности сердца. Обработанные изображения были совмещены с 3D-реконструкцией ЛП, полученной с помощью навигационной системы (CARTO 3, CARTO RMT, «Biosense Webster», «Diamond Bar», США). Высокочастотная стимуляция (ВЧС) с последующей РЧА проводилась с использованием текущих рекомендуемых параметров в ОСА. Кроме того, ВЧС была выполнена в предполагаемых анатомических областях ГС. Изоляция легочных вен с подтверждением наличия блока входа и выхода была выполнена у всех пациентов после абляции ОСА. Повторная сцинтиграфия была проведена через 5–7 дней после абляции, а состояние ритма оценивалось через 6 мес после оперативного вмешательства. Результаты. В общей сложности были выявлены 48 ОСА (медиана 3 [3; 3]) . Активность ОСА составляла 1315 [1171; 1462] имп / с / мл. Положительный ответ на ВЧС в ОСА получен у 8 (53,3 %) пациентов. До абляции не было получено ответа на ВЧС в дополнительных участках ЛП за пределами ОСА. После абляции не было ответа на ВЧС в участках ОСА. При повторной сцинтиграфии ОСА были у 3 пациентов (медиана 0 [0; 0]; р&lt;0,001 по сравнению с дооперационными значениями). Активность ОСА снизилась до 819 [684; 955] имп / с / мл (р&lt;0,001 по сравнению с дооперационными значениями). У 13 (87 %) из 15 пациентов отсутствовали пароксизмы ФП в течение 6 мес наблюдения. Выводы. У пациентов с ФП области симпатической активности ЛП могут быть визуализированы за счет локализации физиологического поглощения 123I-mIBG, что приводит к точному и эффективному радиочастотному воздействию с сохранением синусового ритма у большинства пациентов в периоде наблюдения 6 мес.</p></abstract><trans-abstract xml:lang="en"><p>Introduction: A novel cardiac gamma camera utilizes the radiopharmaceutical Iodine-123-Meta-iodobenzylguanidine (123I-MIBG) to visualize cardiac sympathetic innervation. Physiological accumulation of 123I-mIBG provides an anatomical quantitative determination of the structures of the autonomic nervous system (ANS) with discrete uptake areas (DUA) of sympathetic activity located in the left atrium (LA) corresponding to the main ganglionic plexi (GP) clusters that could not previously be visualized. Aim: to visualize the DUA of the heart in patients with paroxysmal atrial fibrillation (AF) and to assess the effect of radiofrequency ablation (RFA) on DUA in LA. Materials and Methods. Computed tomography (CT) of the heart and radionuclide imaging with 123I-mIBG were performed in 15 patients with paroxysmal AF. The results of the study were combined with preliminary taken CT images to create a detailed anatomical map of the sympathetic activity of the heart. The processed images were combined with the 3D reconstruction of the LA, obtained with the navigation system (CARTO 3, CARTO RMT). In DUA, high-frequency stimulation (HFS) followed by RF ablation was performed using the current recommended parameters. Results. Forty-eight DUA (median 3 [3; 3]) were identified. Average activity of DUA was 1315 [1171; 1462] cnt / sec / ml. Positive response to HFS in the DUA was obtained in 8 (53.3 %) patients. Prior to ablation, no response was received to HFS in areas of LA outside the DUA. After ablation, there was no response to HFS in the DUA sites. At repeated scans 3 DUA (median 0 [0; 0]; p&lt;0.001 compared with preoperative data) were observed. Activity of DUA significantly decreased to 819 [684; 955] cnt / sec / ml (p&lt;0.001 as compared with preoperative data). Thirteen of 13 of 15 patients (87 %) had no AF / AT / AFL recurrences for 6 month follow up. Conclusion. In patients with AF, the areas of sympathetic activity in LA can be visualized by physiological localized uptake of 123I-mIBG. Radiofrequency catheter ablation can target the identified sympathetic innervation structures in AF patients precisely and effectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>автономная нервная система</kwd><kwd>катетерная абляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>autonomic nervous system</kwd><kwd>catheter ablation</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">Calkins H, Hindricks G, Cappato R, Kim Y-H, Saad EB, Aguinaga L et al. 2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation.
