Оценить эффективность криоизоляции при различных анатомических вариантах легочных вен.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование вошло 230 пациентов в возрасте 57 (53; 62) лет, примерно равная доля мужчин и женщин. До 1/3 страдали изолированной ФП, большая часть относилась к категории высокого риска тромбоэмболических осложнений. Для оценки анатомического варианта ЛВ применялась модифицированная классификация E. Marom et al. В группах криобаллонной и радиочастотной изоляции ЛВ выделялись подгруппы типичной и вариантной анатомии. Оценка эффективности вмешательства базировалась на выявлении любых (симптомных и асимптомных) документированных эпизодов предсердных аритмий длительностью более 30 секунд за период наблюдения 12 месяцев.</p></sec><sec><title>Результаты</title><p>Результаты. Сравнение эффективности при типичной анатомии ЛВ не выявило достоверных различий между группами крио и РЧА независимо от вида применяемого устройства. Подгруппа I генерации криобаллонов продемонстрировала свободу от ФП 83,2%, II генерации – 87,5%, группа РЧА – 82,7% при р = 0,82. В то же время, при вариантной анатомии ЛВ эффективность криоизоляции с применением II генерации устройств составила 52,2 против 85,7% в группе РЧА (ОШ = 0,25; 95% ДИ 0,09–0,71; р = 0,02). При проведении анализа отдаленных результатов в группах крио и РЧА в зависимости анатомического варианта было установлено, что при РЧА наличие общего устья слева (коллектора/вестибюля), а также наличие добавочных вен, демонстрировало результаты, сопоставимые с группой типичной анатомии. В то же время, в группе криоаблации наличие общего устья слева сопровождалось снижением эффективности до 23,1 против 84,9% при типичной анатомии (ОШ = 0,14; 95% ДИ 0,03–0,6; p = 0,02) и 90% при наличии добавочных вен (ОШ = 0,1; 95% ДИ 0,01–0,64; р = 0,02). При наличии общего устья слева эффективность криоаблации с применением баллонов второй генерации составила 23,1 против 82,4% в группе РЧА (ОШ = 0,16; 95% ДИ 0,05–0,5).</p></sec><sec><title>Заключение</title><p>Заключение. Наличие общего устья левых легочных вен приводит к снижению эффективности криоаблации в отдаленном периоде наблюдения относительно группы типичной анатомии до 23,1 против 84,9% (ОШ = 0,14; 95% ДИ 0,03–0,6) и 82,4% при радиочастотной аблации (ОШ = 0,16; 95% ДИ 0,05–0,5). Наличие добавочных вен правосторонней локализации не влияет на эффективность вмешательства.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To estimate the efficacy of pulmonary veins (PV) cryoballoon isolation in its different anatomical variants.</p></sec><sec><title>Methods</title><p>Methods. 230 patients 57 (53; 62) years of age were enrolled in the study in approximately equal proportion of males and females. Up to 1/3 of patients suffered from isolated AF, most of them belonged to the category of high risk of thromboembolic complications. To evaluate the PV anatomical variant, a modified classification of E. Marom et al was used. In groups of cryoballoon and radio-frequency isolation, subgroups of typical and variant anatomy were distinguished. Evaluation of the effectiveness of the intervention was based on the identification of any (symptomatic and asymptomatic) documented episodes of atrial arrhythmias lasting more than 30 seconds during the observation period of 12 months.</p></sec><sec><title>Results</title><p>Results. Comparison of efficacy in typical PV anatomy did not reveal significant differences between cryo and RFA groups, regardless of the type of device used. Subgroup I of generation of cryoballoons showed freedom from AF 83.2%, II generation – 87.5%, RFA group – 82.7% at p = 0.82. At the same time, with PV variant anatomy, the efficiency of cryo isolation with the use of II generation devices was 52.2 versus 85.7% in the RFA group (OR = 0.25; 95% CI 0.09–0.71; p = 0, 02). When analyzing long-term results in cryo and RFA groups depending on the anatomical variant, it was found that with RFA, the presence of a left PV common trunk (collector / vestibule), as well as the presence of additional veins, showed results comparable with the group of typical anatomy. At the same time, in the cryoablation group, the presence of a left common trunk was accompanied by a decrease in efficiency to 23.1 versus 84.9% for typical anatomy (OR = 0.14; 95% CI 0.03–0.6; p = 0.02) and 90% in the presence of additional veins (OR = 0.1; 95% CI 0.01–0.64; p = 0.02). In the presence of a left common trunk, the efficiency of cryoablation using second-generation cylinders was 23.1 versus 82.4% in the RFA group (OR = 0.16; 95% CI 0.05–0.5).</p></sec><sec><title>Conclusion</title><p>Conclusion. The presence of a left PV common trunk leads to a decrease in the effectiveness of cryoablation in the long-term observation period relative to the group of typical anatomy to 23.1 versus 84.9% (OR = 0.14; 95% CI 0.03–0.6) and 82.4% for radiofrequency ablation (OR = 0.16; 95% CI 0.05–0.5). The presence of additional veins of right-sided localization does not affect the effectiveness of the intervention.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>легочные вены</kwd><kwd>криобаллонная изоляция</kwd><kwd>радиочастотная аблация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>pulmonary veins</kwd><kwd>cryoballoon isolation</kwd><kwd>radiofrequency ablation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования РФ в рамках поисковых научных исследований «Криобаллонная изоляция легочных вен для повышения безопасности интервенционного лечения фибрилляции предсердий» на базе Федерального государственного бюджетного научного учреждения «Научно-исследовательского института комплексных проблем сердечно-сосудистых заболеваний».</funding-statement></funding-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 YH, Saad EB, Aguinaga L, Akar JG, Badhwar V, Brugada J, Camm J, Chen PS, Chen SA, Chung MK, Cosedis Nielsen J, Curtis AB, Davies DW, Day JD, d'Avila A, Natasja de Groot NMS, Di Biase L, Duytschaever M, Edgerton JR, Ellenbogen KA, Ellinor PT, Ernst S, Fenelon G, Gerstenfeld EP, Haines DE, Haissaguerre M, Helm RH, Hylek E, Jackman WM, Jalife J, Kalman JM, Kautzner J, Kottkamp H, Kuck KH, Kumagai K, Lee R, Lewalter T, Lindsay BD, Macle L, Mansour M, Marchlinski FE, Michaud GF, Nakagawa H, Natale A, Nattel S, Okumura K, Packer D, Pokushalov E, Reynolds MR, Sanders P, Scanavacca M, Schilling R, Tondo C, Tsao HM, Verma A, Wilber DJ, Yamane T; Document Reviewers:. 2017 HRS/EHRA/ECAS/ APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation.
