Создание блока в кавотрикуспидальном перешейке одновременно с изоляцией легочных вен показано всем пациентам с документированным в анамнезе или индуцированным интраоперационно типичным трепетанием предсердий. Вопрос о выполнении превентивной аблации кавотрикуспидального перешейка в настоящее время открыт. В работе проанализированы факторы риска возникновения типичного трепетания предсердий после изоляции устьев легочных вен.</p></sec><sec><title>Цель</title><p>Цель. Определить необходимость превентивной аблации кавотрикуспидального перешейка пациентам, которым планируют проведение изоляции устьев легочных вен; оценить связь факторов риска трепетания предсердий (ТП) и отдаленных результатов изоляции устьев легочных вен.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование является одноцентовым ретроспективным, выполнено с 2015 по 2018 г. Критерии включения: пароксизмальная форма фибрилляции предсердий (ФП), отсутствие документированного ТП. Критерии исключения: типичное или атипичное ТП в анамнезе. Конечные точки: основные сердечно-сосудистые события, повторные операции, возникновение типичного ТП. В исследование вошли 632 пациента. Первичная конечная точка: отсутствие пароксизмов ФП и ТП во время «слепого» периода. Вторичная конечная точка: отсутствие пароксизмов ФП, задокументированных по данным электрокардиографии или Холтеровского мониторирования. Период наблюдения составил 12 мес. Всем больным выполнена изоляция легочных вен.</p></sec><sec><title>Результаты</title><p>Результаты. В течение «слепого» периода (3 мес.) пароксизм ФП зарегистрирован у 148 (23,7%) пациентов. Эффективность операции в течение года составила 78,2% (n = 494) случаев, в 21,8% (n = 138) случаев возник рецидив тахикардии: у 28 пациентов (4,4%) выявлено ТП, у 110 (17,4%) пациентов - ФП. Факторы риска ТП: хроническая обструктивная болезнь легких отмечена у 18 (64,29%) пациентов (отношение шансов, ОШ, 25,4; 95% доверительный интервал, ДИ, 10,991-58,609), хроническая сердечная недостаточность - у 20 (71,43%) больных (ОШ 7,434; 95% ДИ 3,209-17,225), удлиненный интервал p-r - у 18 (64,29%) (ОШ 5,77; 95% ДИ 2,288-14,5), у 6 (28,57%) пациентов выявлен инфаркт миокарда в анамнезе (ОШ 6,591; 95% ДИ 2,447-17,751) и у 7 (67,86%) - курение (ОШ 11,034; 95% ДИ 4,849-25,112).</p></sec><sec><title>Заключение</title><p>Заключение. По нашим данным, хроническая обструктивная болезнь легких, хроническая сердечная недостаточность, инфаркт миокарда в анамнезе, а также курение увеличивают время правопредсердного проведения, тем самым повышая риск возникновения ТП в послеоперационном периоде. Пациентам с факторами риска ТП следует рассмотреть вопрос о проведении превентивной аблации кавотрикуспидального перешейка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Highlights</title><p>Highlights. Cavatricuspid isthmus ablation with pulmonary vein isolation is indicated to all patients with documented or intraoperatively induced typical atrial flutter. The preventive cavatricuspid isthmus ablation remains an issue of concern. The article discusses the risk factors for the onset of typical atrial flutter pulmonary vein isolation.</p></sec><sec><title>Aim</title><p>Aim. To determine the need for preventive ablation of the cavatricuspid isthmus in patients referred to elective pulmonary vein isolation.</p></sec><sec><title>Methods</title><p>Methods. 632 patients (the mean age of 63 years) were enrolled in a single-center retrospective study between 2015 to 2018. The inclusion criteria were as follows: paroxysmal AF, absence of documented AFL. All patients underwent pulmonary vein isolation. The exclusion criteria were as follows: a history of typical or AFL. The endpoints included major cardiovascular events, reoperations, occurrence of AFL. The primary endpoint was the absence of paroxysms of AF and AFL during the blind period. The secondary endpoint was the absence of AF paroxysms documented on the ECG or according to Holter monitoring data. The follow-up period was 12 months.</p></sec><sec><title>Results</title><p>Results. During the blind period, AF paroxysms were recorded in 148 (23.7%) patients. The efficiency of the operation within one year was 78.2% (494 patients). 138 patients (21.8%) had recurrent tachycardia. Of them, 28 patients (4.4%) were diagnosed with atrial fibrillation and others (17.4%) had AFL. Risk factors for AFL included COPD found in 18 patients (64.29%) (OR 25.4; CI 95%; 10.991-58.609), chronic heart failure in 20 patients (71.43%) (OR 7.434; CI 95%; 3.209-17.225), prolonged pr interval in 18 patients (64.29%) (OR 5.77; CI 95%; 2.288-14.5), a history of myocardial infarction in 6 patients (28.57%) (OR 6.591; CI 95%; 2.447-17.751), and smoking in 7 patients (67.86%) (OR 11.034; CI 95%; 4.849-25.112).</p></sec><sec><title>Conclusion</title><p>Conclusion. Chronic obstructive pulmonary disease, chronic heart failure, a history of myocardial infarction, and smoking prolong right atrial conduction time, thereby increasing the risk of AFL in the postoperative period. Preventive cavatricuspid isthmus ablation should be considered in patients with risk factors for developing AFL.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Фибрилляция предсердий</kwd><kwd>Типичное трепетание предсердий</kwd><kwd>Радиочастотная аблация</kwd><kwd>Фактор риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Atrial fibrillation</kwd><kwd>Typical atrial flutter</kwd><kwd>Radiofrequency ablation</kwd><kwd>Risk factors</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">Струтынский А.
