Определить механизмы возникновения и подходов к интервенционному лечению постоперационных предсердных тахикардий у пациентов после торакоскопической аблации фибрилляции предсердий (ФП).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проанализированы результаты торакоскопической аблации ФП 46 пациентов. 19,5% (9) имели предсердные тахикардии в послеоперационном периоде, что вторым этапом потребовало интервенционного вмешательства после трехмесячного “слепого периода”. Во время процедуры катетерной аблации независимо от характера тахикардии выполнялась анатомическая реконструкция левого и правого предсердия с построением высокоплотных вольтажных карт для визуализации повреждений, компетентности изоляции легочных вен (ЛВ) и задней стенки левого предсердия (ЛП). После проведения радиочастотной аблации и восстановления синусового ритма, выполнялось повторное построение высокоплотных карт для верификации блокады проведения и отсутствия электрической активности в местах воздействий.</p></sec><sec><title>Результаты</title><p>Результаты. Полная изоляция ЛВ верифицирована у 5 из 9 пациентов, остаточная фрагментированная спайковая активность с отсутствием проведения в ЛП при стимуляции ЛВ — 4 пациентов. 22,2% (2) пациентов имели типичное истмус-зависимое трепетание предсердий (ТП), которое устранено радиочастотной аблацией каватрикуспидального перешейка. У 77,7% (7) выявлено атипичное левопредсердное ТП. Из них 66,6% (6) пациентов имели зону несостоятельной торакоскопической аблации, которая верифицировалась в области крыши ЛП — верхняя линия при выполнении “Box”. Перимитральное ТП с верификацией зоны замедленного проведения по передней стенке ЛП выявлено у 11,1% (1) пациентов. В данных зонах были выполнены эффективные РЧ-воздействия. Выявлены 2 основных фактора, влияющих на несостоятельность линий аблации: объем ЛП и индекс массы тела (ИМТ). В группе с аритмиями объем ЛП составил 180,2±35,6 мл vs 158,34±38,5 мл в группе пациентов, сохранявших стабильный синусовый ритм, а ИМТ составил 30,8±3,1 кг/м2, vs 28,9±3,9 кг/м2, соответственно. Средний срок наблюдения составил 9,8±2,7 мес. Все пациенты после катетерной аблации сохранили стабильный синусовый ритм.</p></sec><sec><title>Заключение</title><p>Заключение. Причинами возникновения предсердных аритмий после торакоскопической аблации ФП служат несостоятельные линии аблации. Основными предикторами несостоятельности линейных воздействий и возникновения аритмий являются большой объем ЛП и высокий ИМТ пациента. Использование высокоплотного картирования позволяет повысить эффективность устранения аритмий. Сочетание эпи- и эндокардиальных доступов является наиболее эффективным подходом хирургического лечения персистирующих форм ФП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To determine the mechanisms of development and approaches to interventional treatment of postoperative atrial tachycardia in patients after thoracoscopic ablation (TA) of atrial fibrillation (AF).</p></sec><sec><title>Material and methods</title><p>Material and methods. The results of thoracoscopic ablation of AF in 46 patients were analyzed, of which 19,5% (n=9) had atrial tachycardia after the procedure. Radiofrequency ablation (RFA) was conducted in these patients after a 3-month blanking period. Regardless of tachycardia type, the threedimensional reconstruction including high-density right and left atrial (LA) voltage mapping was performed in order to visualize the lesions, pulmonary veins and LA posterior wall isolations. After RFA and sinus rhythm restoration, re-mapping was performed to assess conduction block and absence of electrical activity in the lesion zones.</p></sec><sec><title>Results</title><p>Results. Complete pulmonary vein (PV) isolation was verified in 55,5% of patients (n=5). In 44,4% (n=4), there were residual PV fractionated potentials without conduction with LA. In 22,2% of subjects (n=2), we identified typical atrial flutter (AFL), which was terminated by RFA in cavotricuspid isthmus (CTI). There were 77,7% (n=7) of patients who were diagnosed with atypical LA flutter; 66,6% (n=6) of them had conduction reconnection at the thoracoscopic box-lesion line. Perimitral AFL with slow conduction zone which was located on the anterior wall of LA was verified in 11,1% of patients (n=1). The effective RFA was performed in these areas.</p><p>Two main factors affecting failed ablation were LA volume and body mass index (BMI). In patients with arrhythmias after TA, LA volume was 180,2±35,6 ml vs 158,34±38,5 ml in patients with sinus rhythm. BMI was 30,8±3,1 kg/m2 and 28,9±3,9 kg/m2, respectively. The mean follow-up was 9,8±2,7 months. All patients after catheter ablation maintained a stable sinus rhythm.</p></sec><sec><title>Conclusion</title><p>Conclusion. Atrial tachycardia after TA is caused by the gaps in box-lesion lines. The main predictors of gaps are high values of LA volume and BMI. The high-density mapping increases the effectiveness of RFA. Combination of epicardial and endocardial accesses is the most effective approach to treatment of patients with persistent AF.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>торакоскопическая аблация</kwd><kwd>предсердные тахикардии</kwd><kwd>высокоплотное картирование</kwd><kwd>радиочастотная аблация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>thoracoscopic ablation</kwd><kwd>atrial tachycardia</kwd><kwd>high-density mapping</kwd><kwd>radiofrequency 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">Kirchhof P, Benussi S, Kotecha D, at al. 2016 ESC Guidelines for the management of atrial fibrillation developed in collaboration with EACTS.
