Впервые в рамках проспективного рандомизированного исследования проведена сравнительная оценка среднесрочных результатов применения нового биологического кольца NeoRing (ЗАО «НеоКор», Кемерово) и кольца RIGID (ЗАО НПП «МедИнж», Пенза) для аннулопластики митрального клапана при дисплазии соединительной ткани. Определены предикторы смены синусового ритма на фибрилляцию предсердий и возврата значимой митральной недостаточности в среднесрочном периоде наблюдения.Цель. Сравнительный анализ среднесрочных результатов применения опорных колец NeoRing и RIGID в хирургии митральной недостаточности (МН).Материалы и методы. С ноября 2019 г. по март 2022 г. 62 пациентам с диспластической МН выполнена реконструкция митрального клапана (МК) с применением полужестких колец NeoRing (ЗАО «НеоКор», Кемерово; n = 31) и жестких колец RIGID (ЗАО НПП «МедИнж», Пенза; n = 31). По исходным данным различий между группами не выявлено.Результаты. Зарегистрировано два летальных случая в госпитальном периоде в группе RIGID. Оба устройства показали удовлетворительный клинический эффект на госпитальном этапе в виде восстановления запирательной функции МК (p&lt;0,001) и частоте выявленной максимальной резидуальной МН до 1-й степени в группах NeoRing (9,7%) и RIGID (29%) соответственно, статистически значимых межгрупповых различий не обнаружено (p = 0,292). Через 12 мес. свобода от МН ≥2 степени в группе NeoRing составила 93,5%, в группе RIGID – 77,4% (p = 0,147). У пациентов с RIGID отмечены более высокие показатели трансклапанного диастолического градиента на МК – Pср. 3,70 [3,00–4,40] против 2,3 [2,05–2,85] мм рт. ст. для NeoRing (p&lt;0,001), а также более высокая скорость трансклапанного потока – Vср. 79 [71–94] против 70 [64–79] см/с соответственно (p = 0,017). Проанализировано достижение комбинированной первичной конечной точки в зависимости от имплантируемого устройства, шансы достижения по суммируемым критериям (рецидив митральной регургитации ≥2 степени, MACCE, впервые зарегистрированные нарушения ритма, реоперации) в группе RIGID были в 3,067 раза выше, чем в группе NeoRing; различия шансов статистически значимые (95% ДИ 1,053–8,934; p = 0,037).Заключение. При аннулопластике фиброзного кольца МК жесткими и полужесткими опорными кольцами не продемонстрировано существенной разницы отдаленной выживаемости и рецидивов МН. С учетом статистически значимых различий в достижении комбинированной конечной точки, более низких госпитальных и отдаленных показателей трансмитрального диастолического градиента, а также положительного влияния на обратное ремоделирование камер сердца сделан вывод, что клапаносохраняющая пластика МК полужесткими кольцами типа NeoRing при дисплазии соединительной ткани является предпочтительным вариантом.</p></abstract><trans-abstract xml:lang="en"><p>Highlights. For the first time, as part of a prospective randomized study, a comparative assessment of the mid-term results of mitral valve annuloplasty using a new biological NeoRing ring (CJSC NeoKor, Kemerovo) and a RIGID ring (CJSC NPP MedInzh, Penza) in patients with connective tissue dysplasia was carried out. Predictors of the conversion of sinus rhythm to atrial fibrillation and residual mitral insufficiency in the medium-term follow-up period were determined.Aim. To analysis and compare mid-term results of mitral valve annuloplasty conducted using NeoRing и RIGID rings.Methods. From November 2019 to March 2022, 62 patients with mitral valve (MV) dysplasia underwent MV annuloplasty using NeoRing semi-rigid rings (CJSC NeoKor, Kemerovo, n = 31) and rigid RIGID rings (CJSC NPP MedInzh, Penza, n = 31). There were no differences between the groups at baseline.Results. Two deaths were registered during inpatient treatment in the RIGID group. Both devices showed a satisfactory outcome during inpatient treatment in the form of restoration of MV function (p&lt;0.001) and the frequency of detected maximum residual mitral regurgitation (MR) up to grade 1 in the NeoRing group 9.7% and in the RIGID group 29%, respectively, no statistically significant intergroup differences were noted (p = 0.292). After 12 months, freedom from ≥2 grade MR in the NeoRing group was 93.5% and 77.4% in the RIGID group (p = 0.147). In the RIGID group, patients had higher values of the transvalvular mitral diastolic gradient – PAV 3.70 [3.00–4.40] mm Hg vs. NeoRing group 2.3 [2.05–2.85] mmHg (p&lt;0.001), as well as a higher transvalvular flow rate – VAV 79 [71–94] cm/sec vs. 70 [64–79] cm/sec (p = 0.017). The analysis of the achievement of composite primary endpoint (recurrence of ≥2 grade MR, MACCE, new onset arrhythmias, reoperations) by the device was carried out. The composite endpoint rate in the RIGID group was 3.067 times higher compared to the NeoRing group, odds differences were statistically significant (p = 0.037, 95% CI: 1.053–8.934).Conclusion. The outcome of MV annuloplasty conducted using rigid and semi-rigid rings revealed no significant differences in long-term survival and recurrence of MR between groups. Given the statistically significant difference in achieving the combined endpoint, lower inpatient and long-term indicators of transmitral pressure gradient, and a positive effect on cardiac chambers reverse remodeling, it was concluded that the use of semi-rigid NeoRing rings for MV annuloplasty when performing valvepreserving operations for connective tissue dysplasia is preferable.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Дегенеративные заболевания митрального клапана</kwd><kwd>Митральная недостаточность</kwd><kwd>Аннулопластика митрального клапана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Degenerative mitral valve disease</kwd><kwd>Mitral insufficiency</kwd><kwd>Mitral valve annuloplasty</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">Yadgir S., Johnson C.O., Aboyans V., Adebayo O.M., Adedoyin R.A., Afarideh M., Alahdab F., Alashi A., Alipour V., Arabloo J. et al.; Global Burden of Disease Study 2017 Nonrheumatic Valve Disease Collaborators.
