Сравнить эффективность повторной катетерной аблации кавотрикуспидального перешейка (КТП) у пациентов с типичным трепетанием предсердий (ТП) при стандартном подходе и с использованием внутрисердечной эхокардиографии (ВСЭхоКГ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 112 пациентов с рецидивом ТП после катетерной аблации КТП. В соответствии с технической возможностью применения ВСЭхоКГ пациенты разделены на две группы: в первой группе аблация проводилась с использованием ВСЭхоКГ (54 пациента), во второй группе, контрольной, 58 пациентам аблация выполнялась по стандартной методике, только под контролем флюороскопии. ВСЭхоКГ позволила определить особенности строение КТП у пациентов с рецидивами ТП: утолщение проксимальной части КТП &gt;7 мм (35%), утолщение основания евстахиева клапана &gt;7 мм (48%), неоднородная центральная часть КТП (13%). Проводилась оценка достижения двунаправленной блокады проведения в КТП: в группе ВСЭхоКГ — 52/54 (96,3%), в контрольной группе — 52/58 (89,7%), Р=0,27. Срок наблюдения пациентов составил 24 мес.</p></sec><sec><title>Результаты</title><p>Результаты. Средняя продолжительность процедуры аблации была выше в группе ВСЭхоКГ (54,0±16,8 мин) в сравнении с группой контроля (46,9±11,9 мин), однако среднее время флюороскопии было существенно ниже в группе ВСЭхоКГ: 2,9±1,1 мин и 6,3±1,8 мин, соответственно, Р=0,003. Повторные рецидивы трепетания предсердий встретились у 3 (5,8%) пациентов группы ВСЭхоКГ и у 8 (13,8%) лиц в контрольной группе (P=0,21).</p></sec><sec><title>Заключение</title><p>Заключение. При повторной катетерной аблации КТП у пациентов с рецидивом типичного ТП выявлены особенности строения КТП, вероятно ассоциированные со снижением эффективности аблации. Использование ВСЭхоКГ при повторной аблации ТП ассоциировано со снижением времени флюороскопии, однако вероятность повторного рецидива ТП одинаково невысока как при стандартной визуализации во время аблации, так и при использовании ВСЭхоКГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To compare the effectiveness of cavotricuspid isthmus reablation in patients with typical atrial flutter (AFL) using a standard approach and intracardiac echocardiography (ICE).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 112 patients with recurrent AFL after cavotricuspid isthmus ablation. Patients were divided into two groups based on the ICE performance potential. In the first group, 54 patients underwent ablation using ICE; in the second (control), 58 patients underwent ablation using a standard fluoroscopy technique. ICE allowed us to assess cavotricuspid isthmus structure in patients with recurrent AFL as follows: proximal isthmus &gt;7 mm (35%), Eustachian valve base &gt;7 mm (48%), and a non-uniform central isthmus (13%). Achievement of bidirectional conduction block in the cavotricuspid isthmus was assessed — 52/54 (96,3%) in the ICE group and 52/58 (89,7%) in the control group (P=0,27). The follow-up period was 24 months.</p></sec><sec><title>Results</title><p>Results. The mean procedure duration was longer in the ICE group (54,0±16,8 min) compared to the control group (46,9±11,9 min). However, the mean fluoroscopy time was significantly shorter in the ICE group — 2,9±1,1 min and 6,3±1,8 min, respectively (P=0,003). AFL recurrence after reablation was detected in 3 (5,8%) patients in the ICE group and in 8 (13,8%) individuals in the control group (P=0,21).</p></sec><sec><title>Conclusion</title><p>Conclusion. During cavotricuspid isthmus reablation in patients with recurrent typical AFL, isthmus structural characteristics were identified that were likely associated with reduced ablation efficacy. The use of ICE in reablation was associated with a reduction in fluoroscopy time. However, the risk of recurrent AF is equally low with both standard imaging and with ISE.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трепетание предсердий</kwd><kwd>кавотрикуспидальный перешеек</kwd><kwd>внутрисердечная эхокардиография</kwd><kwd>радиочастотная катетерная аблация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial flutter</kwd><kwd>cavotricuspid isthmus</kwd><kwd>intracardiac echocardiography</kwd><kwd>radiofrequency catheter ablation</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">Голухова Е.З., Милиевская Е.Б., Филатов А.Г. и др.
