Интраоперационно всем пациентам было выполнено контактное картирование высокой плотности эндокардиальной поверхности ЛП и идентифицированы зоны миокарда сниженной вольтажности в спектре амплитуд ≤ 0,75 мв, ассоциированные с замедлением скорости проведения электрического импульса менее 1 м/с. Данные зоны были помечены как электроанатомический субстрат (ЭАС), после чего была измерена их относительная площадь. Длительность клинического наблюдения за пациентами составила не менее 3 лет, во время которого производился учет рецидивов, их времени, вида и учет повторных интервенционных вмешательств.</p></sec><sec><title>Результаты</title><p>Результаты: Относительная площадь ЭАС составила 13.8±10.3% в группе ПФП и 29.6±18.5% в группе Пер ФП (р=0,02). В течение среднего периода наблюдения 32±7 мес., рецидив ФП после циркулярной РЧКИ ЛВ имел место у 69 (38%) пациентов. Повторное интервенционное лечение проводилось 51  (28%) пациентам. После повторной циркулярной РЧКИ ЛВ рецидив ФП был диагностирован у  31 (19 %) пациентов. По результатам многовариатного регрессионного анализа параметр ЭАС оказался единственным независимым предиктором рецидива ФП после циркулярной РЧКИ ЛВ (HR 1,05, p=0,02). При увеличении относительной площади ЭАС на 10% риск рецидива ФП после циркулярной РЧКИ ЛВ возрастает в 1,6 раз. В случае возникновения рецидива после повторного интервенционного лечения прогностическая значимость ЭАС оказалась еще выше (HR= 1,09, p=0,0018). При увеличении относительной площади ЭАС на 10% риск рецидива ФП после повторной циркулярной РЧКИ ЛВ возрастает в 2,4 раза. </p></sec><sec><title>Заключение</title><p>Заключение: ЭАС является независимым предиктором рецидива ФП после циркулярной изоляции легочных вен. Данный параметр может иметь важное значение дальнейшей разработки методов персонализации и определения оптимальной стратегии интервенционного лечения пациентов с ФП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate an extent of left arrial (LA) electroanatomical substrate (EAS) by the method of high density contact mapping in patients with atrial fibrillation (AF) and estimate its impact on recurrence rate following circular radiofrequency pulmonary veins (PV) isolation in prospective observational study.</p></sec><sec><title>Material and methods</title><p>Material and methods. Totally 181 high symptomatic subjects with paroxysmal (142 pts) and persistent (39 pts) AF, who underwent circular RF PVI were enrolled. We created and prospectively analyzed LA electroanatomical high density bipolar maps. Bipolar signals ≤0.75mV, associated with local conduction velocity delay &lt;1 m/s were tagged on LA maps and considered as EAS. Relative EAS areas outside PV ostia were consistently measured. All of the patients were followed up at least for 3 years and AF recurrence rate and redo procedures were recorded.</p></sec><sec><title>Results</title><p>Results. A mean relative EAS area was 13.8±10.3% and 32.6±18.5% in patients with paroxysmal and persistent AF, respectively (P=0,02). During a mean follow-up of 32±7 months, AF recurrence was diagnosed in 69 (38%) of patients. Following a redo ablation in 51 (28%) of patients, subsequent AF recurrence developed in 31 pts (19%). Multivariate analysis showed that only relative EAS areas was independently associated with AF recurrence (HR 1.05, CI 95% 1.02-1.09, P=0.002) and ach 10% increase in the extent of relative EAS area was associated with a 1.6-fold elevation of AF recurrence rate after the index ablation. But the impact of the EAS on clinical outcome after redo ablation was even higher (HR =1,09, p=0,0018) and each 10% increase in the extent of relative EAS area was associated with a 2.4-fold elevation of AF recurrence rate after a redo ablation.</p></sec><sec><title>Conclusion</title><p>Conclusion. The present study suggests that an extent of LA EAS in patients undergoing PVI — is a significant and independent predictor of AF recurrence. This data can have important role for further development and personalization of strategy of interventional treatment in patients with AF.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>циркулярная изоляция легочных вен</kwd><kwd>риск рецидива фибрилляции предсердий</kwd><kwd>контактное картирование высокой плотности</kwd><kwd>электроанатомический субстрат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>circular isolation of pulmonary veins</kwd><kwd>risk of atrial fibrillation relapse</kwd><kwd>high density contact mapping</kwd><kwd>electroanatomical substrate</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., Kuck K.H., Cappato R., et al: 2012 HRS/EHRA/ECAS Expert Consensus Statement on Catheter and Surgical Ablation of Atrial Fibrillation: recommendations for patient selection, procedural techniques, patient management and follow-up, definitions, endpoints, and research trial design.
