Сравнение отдаленных результатов нерезекционных и резекционных методик реконструкции митрального клапана (МК) при его пролапсе.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное исследование вошли 75 пациентов: 60 пациентов в группу нерезекционных методик (средний возраст 57 (49; 64) лет; 21 женщина), 15 пациентов в группу с резекционной техникой (средний возраст 57 (48; 67) лет; 4 женщины). До операции наблюдалась тяжелая митральная недостаточность (МН) – ERO 43,5 (31; 50) мм2, 96% больных находились во II-III функциональном классе. С учетом ретроспективного набора проводилась псевдорандомизация. Средний период наблюдения составил 8,2 (±2,5) года. Для обследования использована ультразвуковая система Vivid E95 (GE Healthcare) с EchoPAC (версия 204).</p></sec><sec><title>Результаты</title><p>Результаты. Обе группы имели сопоставимые ультразвуковые параметры створок и фиброзного кольца МК с наличием тенденции имплантации опорного кольца большего размера в группе нерезекционных методик реконструкции МК (32±1,7 мм vs 30,8±1,8 мм, р=0,07). Также группы сопоставимы по объемно-функциональным характеристикам левого желудочка. Однако выявлена разница между группами в деформации миокарда левого предсердия в разные фазы сердечного цикла: 22,5 (13;26)% vs 14,5 (12;16)% в фазу резервуара, р=0,04; -13,5 (-10;-19)% vs -10 (-9;-13)% в фазу кондуита, р=0,03; -6,5 (-3;-10)% vs -4 (-2;-6)% в систолу предсердий, р=0,04 в группе нерезекционных и резекционной методик, соответственно. Статистически значимо различались следующие параметры: непланарный угол 171 (164;177) гр. – 162 (158;169) гр., р=0,02, сердечный индекс 4,2 (3,7;4,7) л/мин/м2 – 3,8 (3,4;4,1) л/мин/м2, р=0,03. МН &gt;2 степени не выявлено (38,6% пациентов имеют МН 1 степени, 5% пациентов – МН 2 степени).</p></sec><sec><title>Заключение</title><p>Заключение. Нерезекционные и резекционные методики сопоставимы по параметрам створок и фиброзного кольца МК с тенденцией имплантации опорного кольца большего размера в нерезекционной группе, а также по параметрам левого желудочка, однако в отдаленном послеоперационном периоде имеются отличия в функциональном состоянии левого предсердия, непланарном угле, сердечном индексе, что требует дальнейшего изучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: To compare the long-term results reconstructive non-resection and resection techniques in mitral valve prolapse.</p></sec><sec><title>Material and methods</title><p>Material and methods: 75 adult patients – 60 patients in non-resection techniques group (mean age 57 (49;64) years, 21 female) and 15 patients in resection technique group (mean age 57 (48;67) years, 4 female) with severe degenerative mitral regurgitation (ERO 43,5 (31;50) mm2) underwent mitral valve repair – were included in the retrospective study. Most of patients (96%) were in NYHA class II-III before surgery. Propensity score matching was performed due to retrospective study type. Mean follow-up period was 8,2 (±2,5) year. Ultrasound system Vivid E95 (GE Healthcare) with EchoPAC (version 204) was used for our investigation.</p></sec><sec><title>Results</title><p>Results: Both groups had comparable ultrasound parameters of mitral leaflets and annulus with bigger ring size implantation tendency in non-resection group (32 ± 1,7 mm versus 30,8 ± 1,8 mm, р=0,07). Also the groups were comparable in volume and functional characteristics of left ventricle. However, there was a difference between groups in left atrial strain during cardiac cycle: 22,5 (13;26)% versus 14,5 (12;16)% in reservoir phase, р=0,04; -13,5 (-10;-19)% versus -10 (-9;-13)% in conduit phase,  р=0,03; -6,5 (-3;-10)% versus -4 (-2;-6)% in contractile phase, р=0,04 in non-resection group and resection group accordingly. Statistically significant difference was detected in non-planar angle (171 (164;177) deg. – 162 (158;169) deg., р=0,02) and cardiac index (4,2 (3,7;4,7) l/min/m2 – 3,8 (3,4;4,1) l/min/m2, р=0,03). Patients in both groups had not recurrent MR more than 2 degree (38,6% with MR 1 degree, 5% with MR 2 degree).</p></sec><sec><title>Conclusion</title><p>Conclusion: Non-resection and resection reconstructive techniques are comparable in postoperative parameters of mitral leaflets, annulus and left ventricle with bigger ring size implantation tendency in non-resection group, but there are differences between groups in left atrial strain, non-planar angle, cardiac index in long-term period. However, larger studies are still needed.</p></sec><sec><title>Conflict of interest</title><p>Conflict of interest: Authors have nothing to disclose with regard to commercial support.</p><p>Identifying number of the investigation: The investigation has identifying number NCT03674593 on ClinicalTrials.com.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>реконструкция митрального клапана</kwd><kwd>нерезекционные методики</kwd><kwd>резекционная методика</kwd><kwd>недостаточность митрального клапана</kwd><kwd>продольная деформация левого предсердия</kwd><kwd>3D чреспищеводная эхокардиография.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mitral valve reconstruction</kwd><kwd>non-resection techniques</kwd><kwd>resection technique</kwd><kwd>mitral valve insufficiency</kwd><kwd>left atrial strain</kwd><kwd>3D transesophageal echocardiography.</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">Chen S, Sari CR, Gao H, et al.
