В нашей стране разработан синтетический протез с новой трансфеморальной системой доставки, однако результаты его применения в литературе не представлены.</p><sec><title>Цель исследования</title><p>Цель исследования. По данным мультиспиральной компьютерной томографии (панаортографии) оценить частоту развития госпитальных осложнений в ранний послеоперационный период после транскатетерного протезирования аортального клапана протезом МедИнж у пациентов с дегенеративным стенозом аортального клапана и выявить их потенциальные анатомические предикторы.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено одноцентровое пилотное исследование. В исследование включались пациенты с верифицированным тяжелым стенозом аортального клапана: эффективная площадь отверстия аортального клапана не более 1,0 см2; средний трансклапанный градиент 40 мм рт. ст. и более. Всем пациентам проведено трансфеморальное протезирование с целью коррекции дегенеративного тяжелого стеноза аортального клапана с применением синтетического протеза МедИнж. Операции выполнены в период с 2023 по 2025 гг.</p></sec><sec><title>Результаты</title><p>Результаты. Всего было включено 30 пациентов среднего и высокого хирургического риска, медиана возраста – 75 (68,5; 77,5) лет; 27% составляли мужчины. Частота госпитальных осложнений составила 27% (ОНМК 7%, желудочковые аритмии 7%, острый тромбоз общей подвздошной артерии 7%, острая ишемия миокарда 3%, лимфоцеле 3%). Шансы развития осложнений при проведении транскатетерного протезирования аортального клапана (TAVR) повышаются при наличии минимального диаметра общей подвздошной артерии на стороне оперативного доступа ≤ 10,5 мм, (ОШ = 19,2; 95%ДИ ОШ 1,844– 199,9); при значении продольного диаметра наружной подвздошной артерии ≤ 7,75 мм (ОШ = 25,5; 95%ДИ ОШ 2,5–276); при значении поперечного диаметра ≤ 8,2 мм (ОШ = 8; 95%ДИ ОШ 1,2–55).</p></sec><sec><title>Выводы</title><p>Выводы. Среди пациентов среднего и высокого риска с тяжелым симптоматическим аортальным стенозом, после трансфеморального протезирования аортального клапана протезом МедИнж, частота госпитальных осложнений составила 27%, в том числе сосудистые осложнения – 7%.. Результаты МСКТ панаортографии позволяют предположить, что диаметр общих подвздошных артерий, минимальный диаметр общей подвздошной артерии, продольный и поперечный диаметры наружных подвздошных артерий на стороне оперативного доступа являются потенциальными анатомическими предикторами, ассоциированными с развитием сосудистых осложнений после проведения TAVR.</p></sec></abstract><trans-abstract xml:lang="en"><p>Until recently, the only transcatheter synthetic aortic prostheses available on the Russian market were those with transapical or transaortic delivery systems. A synthetic prosthesis with a novel transfemoral delivery system has been developed in our country; however, the literature contains no data on the results of its use.</p><sec><title>Aim</title><p>Aim: To assess the incidence of in-hospital complications in the early postoperative period following transcatheter aortic valve replacement (TAVR) with the MedInzh prosthesis in patients with degenerative aortic valve stenosis, based on multislice computed tomography (panaortography) data (MSCT), and to identify their potential anatomical predictors.</p></sec><sec><title>Material and methods</title><p>Material and methods. This clinical trial is a prospective, single-center pilot study included patients with confirmed severe aortic stenosis: effective aortic valve orifice area of ≤ 1.0 cm²; mean transvalvular gradient ≥ 40 mmHg. All patients underwent transfemoral valve replacement for correction of severe degenerative aortic stenosis using the synthetic MedInzh prosthesis. All procedures were performed between 2023 and 2025.</p></sec><sec><title>Results</title><p>Results. A total of 30 patients at moderate and high surgical risk were enrolled; median age was 75 (68.5; 77.5) years; 27% were male. The incidence of in-hospital complications was 27% (acute cerebrovascular accident 7%; ventricular arrhythmias 7%; acute common iliac artery thrombosis 7%; acute myocardial ischemia 3%; lymphocele 3%). The odds of complications after TAVR increased when the minimal diameter of the common iliac artery on the access side was ≤ 10.5 mm (OR = 19.2; 95% CI: 1.844–199.9); with the longitudinal diameter of the external iliac artery was ≤ 7.75 mm (OR = 25.5; 95% CI: 2.5–276); and with a transverse diameter was ≤ 8.2 mm (OR = 8; 95% CI: 1.2–55).</p></sec><sec><title>Conclusions</title><p>Conclusions. Among intermediate- and high-risk patients with severe symptomatic aortic stenosis undergoing transfemoral aortic valve replacement with the MedInzh prosthesis, the rate of in-hospital complications was 27%, with vascular complications accounting for 7%. MSCT panaortography results suggest that the diameter of the common iliac arteries, the minimal diameter of the common iliac artery, and the longitudinal and transverse diameters of the external iliac arteries on the access side are potential anatomical predictors associated with the development of vascular complications after TAVR.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аортальный клапан</kwd><kwd>аортальный стеноз</kwd><kwd>компьютерная томография</kwd><kwd>трансфеморальное протезирование аортального клапана</kwd><kwd>клиническое исследование</kwd><kwd>трансфеморальный протез МедИнж</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aortic valve</kwd><kwd>aortic stenosis</kwd><kwd>computed tomography</kwd><kwd>transfemoral aortic valve replacement</kwd><kwd>clinical study</kwd><kwd>MedInzh transfemoral prosthesis</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">Otto C.M., Nishimura R.A., Bonow R.O. et al. 2020 ACC/AHA guideline for the management of patients with valvular heart disease: executive summary: a report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.
