Определить факторы, ассоциированные с 2-месячной эффективностью радиочастотной катетерной аблации (РЧКА) фибрилляции предсердий (ФП) с применением модуля «Индекс аблации» (ИА).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Годовые результаты РЧКА ФП оценены у 243 пациентов, включенных в проспективный регистр аблации ФП с применением ИА. Рецидивы ФП выявлены у 81 (33) пациента.</p></sec><sec><title>Результаты</title><p>Результаты. По итогу наблюдения пациенты были разделены на две группы: с рецидивом аритмии и без. Группы не отличались по основным клинико-демографическим показателям. В группе без рецидива процедуры чаще выполнялись более опытными (&gt;100 РЧКА ФП/год) операторами (65 (80%) vs 145 (86%), р=0,011), медиана фактического ИА по передней и задней стенкам левого предсердия (ЛП) была выше, чем в группе рецидива (424 vs 406, р=0,023 и 395 vs 388, р=0,017). В группе наличия рецидивов отмечалось более короткое среднее межаппликационное расстояние (3,9±0,8 мм vs 4,2±0,9 мм, р=0,04), а также в этой группе чаще наносились дополнительные линейные аппликации в ЛП (9,9% vs 3%, р=0,045). Распределение зон восстановления проводимости в легочных венах (ЛВ) оценено у 43 пациентов: 28 (51%) — передние сегменты левых ЛВ, 23 (41%) — передние сегменты правых ЛВ, 4 (4%) — задние сегменты левых ЛВ и 4 (4%) — задние сегменты правых ЛВ.</p></sec><sec><title> </title><p> </p></sec><sec><title>Заключение</title><p>Заключение. В регистровом исследовании у пациентов с отсутствием рецидива аритмии после РЧКА ФП отмечались более высокие значения медианы ИА (424 единицы по передней стенке и 395 единиц по задней стенке ЛП) и мощность аблации выше 35 Вт на передней стенке ЛП. Независимо от других параметров, с отсутствием рецидивов ФП были ассоциированы опыт оператора (&gt;100 аблаций ФП в год) и отсутствие дополнительных линейных воздействий в ЛП. При повторных процедурах наиболее часто восстановление электрического проведения обнаруживалось в передних сегментах обоих ЛВ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To determine factors associated with the 12-month efficacy of radiofrequency catheter ablation (RFA) of atrial fibrillation (AF) using the Ablation Index (AI) module.</p></sec><sec><title>Material and methods</title><p>Material and methods. Annual results of RFA of AF were assessed in 243 patients included in a Prospective Registry of AF Ablation using the AI module. Recurrent AF was detected in 81 (33%) patients.</p></sec><sec><title>Results</title><p>Results. Patients were divided into two following groups: those with and without recurrent arrhythmia. The groups did not differ in key clinical and demographic parameters. In the non-recurrent group, procedures were more frequently performed by more experienced (&gt;100 RFA/year) operators (65 (80%) vs 145 (86%), p=0,011), and the median actual AI in the left atrial (LA) anterior and posterior walls was higher than in the recurrent group (424 vs 406, p=0,023 and 395 vs 388, p=0,017). In the recurrence group, a shorter mean interapplication distance was noted (3,9±0,8 mm vs, 4,2±0,9 mm (p=0,04), and additional linear LA applications were made more often in this group (9,9% vs 3%, p=0,045). There was following distribution of pulmonary vein (PV) conduction recovery (43 patients): 28 (51%) — left PV anterior segments, 23 (41%) — right PV anterior segments, 4 (4%) — left PV posterior segments, and 4 (4%) — right PV posterior segments.</p></sec><sec><title>Conclusion</title><p>Conclusion. In a registry study, patients without arrhythmia recurrence after RFA had higher median AI values (424 units on the anterior wall and 395 units on the posterior wall of the LA) and ablation power above 35 W on the anterior LA wall. Operator experience (more than 100 AF ablations per year) and the absence of additional linear LA interventions were independent of other parameters and associated with AF non-recurrence. In reprocedures, electrical conduction recovery was most frequently detected in the anterior segments of both PVs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>радиочастотная аблация</kwd><kwd>рецидив</kwd><kwd>регистр</kwd><kwd>индекс аблации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>radiofrequency ablation</kwd><kwd>recurrence</kwd><kwd>registry</kwd><kwd>ablation index</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">Аракелян М.
