Имплантация электрода в проводящую систему сердца (ПСС) на данный момент является наиболее физиологичным методом электрокардиостимуляции. Однако, несмотря на наличие специализированных электродов и систем доставок, доля нецелевых имплантаций весьма существенна. Существует потребность в методике интраоперационной визуализации (МИВ), поскольку контроль положения электрода осуществляется посредством электрофизиологического и флюороскопического методов, чего не достаточно.</p></sec><sec><title>Цель</title><p>Цель: оптимизация имплантации электродов в ПСС посредством применения merge-методики интраоперационной визуализации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В рамках проспективного исследования cформировано 2 группы. Участникам исследуемой группы имплантирован электрод в ПСС (в левую ножку пучка Гиса – ЛНПГ) с использованием оригинальной МИВ, участникам контрольной группы – по классической методике. Всем пациентам после имплантации проведена оценка положения электрода с использованием мультиспиральной компьютерной томографии (МСКТ), трансторакальной эхокардиографии (ЭхоКГ) в раннем послеоперационном периоде, электрокардиографии (ЭКГ). МСКТ до имплантации выполнена пациентам исследуемой группы.</p></sec><sec><title>Результаты</title><p>Результаты. В рамках исследования полный протокол исследования выполнен у 10 пациентов исследуемой группы и у 10 пациентов контрольной. Всем пациентам исследуемой группы подтверждена имплантация электродов в межжелудочковую перегородку (МЖП) (ЭхоКГ, МСКТ), в ПСС (ЭКГ). Продолжительность операции составила 87,5 [70; 120] мин, время флюороскопии – 225 [125; 421] с. Осложнений, нецелевых имплантаций нет. В контрольной группе продолжительность операции – 100 [100; 110] мин, время флюороскопии – 775 [500; 1230] с; стимуляция ПСС подтверждена у 4 (40%) пациентов; зафиксированы 2 (20%) случая перфорации МЖП, 1 (10%) случай имплантации в область верхушки, 1 (10%) случай интраоперационной дислокации правожелудочкового электрода, 1 (10%) случай гемоперикарда в раннем послеоперационном периоде. Средняя погрешность измерений по данным МИВ в сравнении с КТ: расстояние от эндокарда (левый желудочек –ЛЖ) до электрода – 0,98 ± 0,51 мм; от электрода до кольца трехстворчатого клапана (ТК) – 3,1 ± 0,92 мм. По данным трансторакальной ЭхоКГ, структурно-функциональных изменений ТК, участков локального нарушения сократительной способности миокарда, значимых изменений порогов чувствительности, стимуляции, а также послеоперационных дислокаций электродов у пациентов обеих групп нет.</p></sec><sec><title>Выводы</title><p>Выводы. Применение merge-методики интраоперационной визуализации при имплантации электрода в ПСС позволяет снизить количество нецелевых имплантаций, время флюороскопии, лучевую нагрузку на оператора, не увеличивая продолжительность операции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. A lead implantation into the cardiac conduction system (CCS) is currently the most physiological method of pacing. However, despite the availability of specialized lead and delivery systems, the proportion of non-targeted implantations is very significant. There is a need for an intraoperative visualization technique. The lead position is monitored by electrophysiological and fluoroscopic methods, which, obviously, are not enough.</p></sec><sec><title>Aim</title><p>Aim: To optimize the implantation of leads in the conduction system of the heart through the use of intraoperative merge visualization technique (IVT).</p></sec><sec><title>Material and methods</title><p>Material and methods. Two study groups are formed as part of the protocol of a prospective study. In the patients of the study group leads were implanted into the CCS using the IVT; in the control group - by traditional method. After implantation, in all patients the position of the lead using a transthoracic echocardiography (TTE), ECG was assessed. Computed tomography (CT) was performed in patients of study group before and after implantation. In patients of control group CT was performed after implantation.</p></sec><sec><title>Results</title><p>Results. The full study protocol was completed in 10 patients of the study group and in 10 patients of the control group. All patients of the study group confirmed the lead implantation into the interventricular septum (IVS) using TTE and CT; into the CCS using ECG. The duration of the surgery was 87.5 [70; 120] min, fluoroscopy time – 225 [125; 421] sec. Complications, non-target implantations were not registered. In the control group, the duration of the surgery was 100 [100;110] min, the time of fluoroscopy was 775 [500;1230] sec.; stimulation of the CCS was confirmed in 4 (40%) patients; recorded 2 (20%) cases of perforation of the IVS, 1 (10%) case of implantation in the area of the apical part of the right ventricle, 1 (10%) intraoperative dislocation of the right ventricular lead, 1 (10%) case of hemopericardium in the early postoperative period. The average measurement error according to the intraoperative imaging technique compared with MSCT: the distance from the LV endocardium to the lead was 0.98 ± 0.51 mm, the distance from the lead to the tricuspid valve ring was 3.1 ± 0.92 mm. According to trans-thoracic echocardiography, there weren’t structural and functional changes in the tricuspid valve, newly emerged local areas of the myocardium with impaired contractility were detected in patients of the two groups. There weren’t significant changes in sensitivity thresholds, stimulation, and postoperative dislocations of the leads.</p></sec><sec><title>Conclusions</title><p>Conclusions. The use of IVT allows to reduce the number of “off-target” implantations, the time of fluoroscopy, the radiation exposure of the operator and the duration of the surgery.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>проводящая система сердца</kwd><kwd>имплантация электрода</kwd><kwd>интраоперационная система визуализации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac conductive system</kwd><kwd>lead implantation</kwd><kwd>intraoperative visualization technique</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке государственного задания Министерства здравоохранения Российской Федерации: ЕГИСУ НИОКТР 122041500020-5.</funding-statement><funding-statement xml:lang="en">the study was supported by the state task of the Ministry of Health of the Russian Federation USAIS RDTW 122041500020-5.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Furman S., Schwedel J.B.
