Материал и методы: в исследование были включены 37 больных ишемической болезнью сердца, которым была выполнена эпикардиальная перевязка УЛП при коронарном шунтировании на работающем сердце. Средний возраст больных составил 58,7 ± 7,7 года (38-74 года). Большинство пациентов были мужчины - 35 (95%). Артериальная гипертензия и фибрилляция предсердий зарегистрированы у всех больных. Ультразвуковые исследования сердца проводились на аппарате iE33 (Philips, Нидерланды) с использованием секторного датчика 1-5 МГц и чреспищеводного секторного датчика 2-7 МГц. Всем пациентам выполнялся интраоперационный ЧПЭ-мониторинг (до перевязки и после перевязки УЛП). До перевязки УЛП оценивали ширину устья УЛП, длину УЛП, соотношение ширины устья к длине УЛП, площадь УЛП, кровоток в устье УЛП и УЛП при цветовом допплеровском картировании, скорость кровотока в УЛП при импульсноволновой допплерографии. После перевязки УЛП оценивали герметичность перевязки УЛП путем определения сообщения между УЛП и левым предсердием при цветовом допплеровском картировании. Негерметичной перевязку УЛП считали в тех случаях, когда удавалось выявить сообщение между УЛП и левым предсердием. При наличии негерметичной перевязки УЛП определяли диаметр сообщения (ширину устья УЛП после перевязки) между УЛП и левым предсердием. Результаты: негерметичная перевязка УЛП при ЧПЭ выявлена у 10 (27%) пациентов. При анализе данных интраоперационной ЧПЭ до перевязки определены достоверные различия ширины устья УЛП (P = 0,001), соотношения ширины устья УЛП к длине УЛП (P = 0,03) и площади УЛП (P = 0,005) при сравнении пациентов с герметичной и негерметичной перевязкой. Предикторами негерметичной перевязки УЛП могут быть ширина устья УЛП ≥18,4 мм (чувствительность - 60,0%, специфичность - 100,0%), соотношение ширины устья УЛП к длине УЛП ≥0,8 (чувствительность - 30,0%, специфичность - 92,6%) и площадь УЛП ≥4,21 см2 (чувствительность - 60,0%, специфичность - 100,0%). Выводы: частота негерметичной эпикардиальной перевязки УЛП при коронарном шунтировании на работающем сердце составила 27%. Для прогнозирования негерметичной перевязки УЛП при проведении ЧПЭ получен ряд высокоспецифичных критериев, чувствительность которых 30,0-60,0%.</p></abstract><trans-abstract xml:lang="en"><p>Objective: To reveal predictors of incomplete epicardial ligation (isolation) of the left atrial appendage (LAA) during off-pump coronary artery bypass grafting according to intraoperative transesophageal echocardiography (TEE). Material and methods: 37 patients with coronary heart disease (with arterial hypertension and atrial fibrillation in all cases) underwent epicardial LAA ligation during off-pump coronary artery bypass grafting. Mean age of patients was 58.7 ± 7.7 years (38-74 years), 35 (95%) of them were male. Echocardiography utilized iE33 (Philips, Netherlands) with a 1-5 MHz sector probe and a 2-7 MHz transesophageal sector probe. Pre- and post-LAA ligation intraoperative TEE monitoring performed in all cases. In pre-LAA ligation examination, width of LAA ostium, LAA length, width of LAA ostium/LAA length ratio, LAA area, LAA and LAA ostium blood flow, and LAA blood flow velocity were assessed. In post-LAA ligation examination, completeness of ligation was assessed in color Doppler ultrasound. If the presence of communication between LAA and LA was revealed, LAA ligation considered as incomplete and diameter of communication (width of LAA ostium after ligation) was measured. Results: In intraoperative TEE incomplete LAA ligation was detected in 10 (27%) patients. Significant differences of width of LAA ostium (P = 0.001), width of LAA ostium/LAA length ratio (P = 0.03), and LAA area (P = 0.005) between patients with complete and incomplete ligation were found when analyzing the data of pre-ligation intraoperative TEE. Width of LAA ostium ≥18.4 mm (sensitivity - 60.0%, specificity - 100.0%), width of LAA ostium/LAA length ratio ≥0.8 (sensitivity - 30.0%, specificity - 92.6%), and LAA area ≥4.21 cm2 (sensitivity - 60.0%, specificity - 100.0%) can be considered as the predictors of incomplete LAA ligation. Conclusion: The incidence of incomplete epicardial LAA ligation during off-pump coronary artery bypass grafting is 27%. A number of intraoperative TEE criteria for incomplete LAA ligation prognosis with ultra-high specificity were obtained, but sensitivity was only 30.0-60.0%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интраоперационная чреспищеводная эхокардиография</kwd><kwd>перевязка ушка левого предсердия</kwd><kwd>негерметичная перевязка ушка левого предсердия</kwd><kwd>коронарное шунтирование на работающем сердце</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intraoperative transesophageal echocardiography</kwd><kwd>ligation of the left atrium appendage</kwd><kwd>incomplete ligation of the left atrial appendage (unsuccessful left atrial appendage closure)</kwd><kwd>off-pump coronary artery bypass grafting</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">Thomas T.V.
