The greatest effectiveness is achieved when this intervention is performed in young patients without comorbidities and in patients with paroxysmal atrial fibrillation. The appropriateness of performing radiofrequency ablation of the pulmonary vein ostia in elderly patients with atrial fibrillation remains a subject of debate.</p> <p><bold>AIM</bold>: to study the immediate and long-term results of catheter ablation in elderly patients with AF.</p> <p><bold>MATERIALS AND METHODS</bold>: The study group consisted of 88 patients aged 75–88 years who underwent RFA of the pulmonary vein ostia. The technique used was classical, with femoral puncture access, and irrigated ablation catheter. Data analyzed included ECG parameters, incidence of systemic thromboembolic complications, functional class of chronic heart failure according to NYHA, subjective state post-procedure, occurrence of atrial fibrillation recurrences, and the impact of baseline clinical factors on disease recurrence.</p> <p><bold>RESULTS</bold>: In 80 patients (90.9%), atrial fibrillation did not recur during their hospital stay after radiofrequency ablation of the pulmonary vein ostia. In the long term (min 1.5, max 3.1 years), a cross-sectional observational study was conducted on 37 patients. Adherence to oral anticoagulants was 97.6%. No systemic thromboembolic events were recorded among the patients available for contact. Atrial fibrillation recurrences troubled 67.6% of patients after radiofrequency ablation. The main predictors of atrial fibrillation recurrence in elderly patients were the presence of hypertension (<italic>p</italic>=0.03) and baseline left atrial enlargement (<italic>p</italic>=0.001). Despite the high recurrence rate, there was a significant reduction in the functional class of chronic heart failure following radiofrequency ablation of the pulmonary vein ostia (<italic>p</italic>=0.009).</p> <p><bold>CONCLUSIONS</bold>: Strict selection is required for performing catheter ablation in patients with atrial fibrillation older than 75 years. Significant left atrial enlargement and uncontrolled hypertension are major limitations for performing RFA of the pulmonary vein ostia in the elderly. The procedure demonstrates significant effectiveness in terms of reducing chronic heart failure functional class in patients over 75 years old, despite the high recurrence rates in the long term.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Восстановление и поддержание синусового ритма сердца является одним из важнейших аспектов ведения пациентов с фибрилляцией предсердий. Наибольшая эффективность достигается при выполнении данного вмешательства у некоморбидных пациентов молодого возраста и при пароксизмальной форме фибрилляции предсердий. Целесообразность выполнения радиочастотной абляции устьев легочных вен у больных с фибрилляцией предсердий старческого возраста на сегодняшний день остается предметом дискуссий.</p> <p><bold>Цель</bold> — изучить ближайшие и отдаленные результаты радиочастотной абляции устьев легочных вен у больных с фибрилляцией предсердий старческого возраста.</p> <p><bold>Материалы и методы</bold>. Исследуемая группа была сформирована из 88 пациентов в возрасте 75–88 лет, которым была выполнена радиочастотная абляция устьев легочных вен. Техника проведения классическая, с пункционным бедренным доступом. Анализировались такие данные, как показатели электрокардиограммы, наличие системных тромбоэмолических осложнений, функциональный класс хронической сердечной недостаточности по NYHA, субъективное состояние после вмешательства, наличие рецидивов фибрилляции предсердий, влияние исходных клинических факторов на рецидив заболевания.</p> <p><bold>Результаты</bold>. В 80 (90,9%) случаях после радиочастотной абляции устьев легочных вен за время нахождения в стационаре фибрилляция предсердий не рецидивировала. В отдаленные сроки (от 1,5 до 3,1 года) проведен поперечный обсервационный срез у 37 пациентов. Приверженность пероральным антикоагулянтам составила 97,6%. Системных тромбоэмболических осложнений среди доступных для контакта больных зарегистрировано не было. Рецидивы фибрилляции предсердий после радиочастотной абляции устьев легочных вен беспокоили 67,6% пациентов. Основными предикторами рецидива фибрилляции предсердий у больных старческого возраста стали гипертоническая болезнь (<italic>р</italic>=0,03) и исходная дилатация левого предсердия (<italic>р </italic>= 0,001). Несмотря на большую долю рецидивов, выявлено значимое снижение функционального класса хронической сердечной недостаточности после радиочастотной абляции устьев легочных вен (<italic>р</italic>=0,009).</p> <p><bold>Заключение</bold>. Требуется строгий отбор пациентов с фибрилляцией предсердий старше 75 лет для проведения радиочастотной абляции устьев легочных вен. Выраженная дилатация левого предсердия и неконтролируемая артериальная гипертензия является значимым ограничением для выполнения радиочастотной абляции устьев легочных вен в старческом возрасте. Методика показывает значимую эффективность в плане снижения ФК ХСН у пациентов старше 75 лет, несмотря на большую частоту рецидивов в отдаленные сроки.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>radiofrequency catheter ablation</kwd><kwd>surgical treatment of cardiac rhythm disorders</kwd><kwd>elderly patients</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>радиочастотная катерная абляция</kwd><kwd>хирургическое лечение нарушений ритма сердца</kwd><kwd>пациенты старческого возраста</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Arakelyan MG, Bockeria LA, Vasilieva EYu, et al. 2020 Clinical guidelines for atrial fibrillation and atrial flutter.
