Оценить влияние катетерной аблации на изменение функций левого (ЛП) и правого предсердий (ПП) у пациентов с фибрилляцией предсердий (ФП).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 28 пациентов (14 мужчин и 14 женщин) в возрасте от 33 до 72 лет (средний возраст 57,7±9,9 лет) с пароксизмальной (n=23) и персистирующей формами ФП (n=5). Всем пациентам выполнялась радиочастотная аблация (РЧА) с антральной изоляцией устьев легочных вен. До катетерного лечения и через 3 дня после проводилась трансторакальная двухмерная эхокардиография на синусовом ритме с оценкой резервуарной, проводниковой, насосной функций ЛП и пиковой продольной деформации ПП.</p></sec><sec><title>Результаты</title><p>Результаты. У исследованных пациентов выявлено статистически значимое снижение резервуарной, проводниковой и насосной функции ЛП после проведения РЧА, в то время как статистически значимого изменения пиковой продольной деформации ПП после катетерной аблации не зарегистрировано. Функция резервуара ЛП уменьшилась на 6,45%, (р&lt;0,001); функция проводника на 3,59% (р&lt;0,001); насосная функция на 2,85% (р&lt;0,001); пиковая продольная деформация ПП увеличилась на 0,73% (р=0,43).</p></sec><sec><title>Заключение</title><p>Заключение. Катетерная аблация оказывает значимое повреждающее действие на ткань ЛП, угнетая резервуарную, насосную и проводниковую функции. При этом сократительная способность ПП в раннем послеоперационном периоде улучшается незначимо.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate the effect of catheter ablation on left (LA) and right atria (RA) function in patients with atrial fibrillation.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 28 patients (14 men and 14 women) aged 33 to 72 years (mean age, 57,7±9,9 years) with paroxysmal (n=23) and persistent AF (n=5). All patients underwent radiofrequency ablation (RFA) with pulmonary vein antrum isolation. Before ablation and 3 days after, transthoracic twodimensional echocardiography was performed in sinus rhythm with an assessment of LA reservoir, conduit and booster pump function and RA peak longitudinal strain.</p></sec><sec><title>Results</title><p>Results. In the studied patients, a significant decrease in the reservoir, conduit and booster pump function of the LA was revealed after RFA, while there was no significant change in RA peak longitudinal strain after catheter ablation. LA reservoir, conduit and booster pump function decreased by 6,45% (p&lt;0,001), 3,59% (p&lt;0,001), 2,85% (p&lt;0,001), respectively, while RA peak longitudinal strain increased by 0,73% (p=0,43).</p></sec><sec><title>Conclusion</title><p>Conclusion. Catheter ablation has a significant damaging effect on the LA tissue, inhibiting the reservoir, pumping and pipeline functions. At the same time, the contractility of the PP in the early postoperative period improves, but not significantly.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>катетерная аблация</kwd><kwd>левое предсердие</kwd><kwd>правое предсердие</kwd><kwd>фиброз предсердий</kwd><kwd>speckle tracking</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>catheter ablation</kwd><kwd>left atrium</kwd><kwd>right atrium</kwd><kwd>atrial fibrosis</kwd><kwd>speckle tracking</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">Bajraktari G, Bytyсi I, Henein MY.
