“…[3]. Ранее были опубликованы непосредственные и среднесрочные результаты AVNeo, однако у некоторых пациентов в отдаленном периоде может возникать дисфункция неоАК и привести к повторным вмешательствам [4][5][6][7][8][9][10][11]. Так, по данным последнего систематического обзора свобода от реоперации в течение 1, 3, 5 лет после AVNeo составила 98, 97 и 96 % соответственно [11].…”

Introduction. One of surgical methods for treatment of aortic valve (AV) pathology is Aortic Valve Neocuspidalization Ozaki procedure (AVNeo). Thus, according to the latest systematic review, freedom from reoperation within one, three, five years after AVNeo was 98%, 97% and 96%. Available references provide few descriptions of reoperations after AVNeo. Aim. To analyze the immediate results of AV reinterventions after AVNeo. Materials and methods. In the medium term, reinterventions after AVNeo were necessary for 11 patients (4.3%). The age of patients ranged from 26 to 69 years. 11 patients who underwent surgery included 6 males and 5 females. Four patients had class III-IV CHF, according to NYHA classification. Three patients had previously been operated on for infective endocarditis (IE), and five patients had bicuspid aortic valve. The duration of follow-up, from AVNeo surgery to reinterventions, ranged from 3 to 43 months. Results and discussion. All patients underwent an isolated AV intervention. The main causes of dysfunction were IE (six patients) and leaflet rupture in the commissural area (five patients). Seven patients underwent aortic valve replacement with mechanical valves, one patient — with aortic homograft valve, one patient — with tissue valve and two patients underwent valve repair. In the early postoperative period, one patient had bleeding with the development of cardiac tamponade and one patient had a haemorrhagic stroke. No patients had ARF, perioperative myocardial damage, sternal infection or permanent pacemaker implantation. Two patients died during the hospital period. Conclusions. AV reinterventions are associated with a high incidence of complications and deaths. Therefore, prevention of IE and commissure enhancement should reduce the frequency of repeated interventions, which is to be confirmed by prospective studies in large cohorts of patients.

“…В другой работе при анализе 253 операций протезирования аортального клапана у пациентов при среднем возрасте 70,4±4,14 года общая госпитальная летальность составила 10,3%; при изолированном протезировании аортального клапана -4,8%, а при сочетанных вмешательствах -8,8% [8]. При выполнении протезирования аортального клапана аутоперикардом по Ozaki частота летального исхода варьирует от 1 до 3% в разных центрах [1,7,9]. Различия в частоте осложнений обусловлены типами вмешательств, проводимыми в различных учреждениях.…”

Aim. To determine the incidence and predictors of cardiovascular events in onpump cardiac operations in modern practice.Material and methods. The study included 200 patients who underwent various elective cardiac surgical interventions. Cardiovascular events (CVEs) were determined within 30 days from the operation, according to medical records and autopsy protocols. We identified major CVEs (cardiovascular death, stroke, myocardial infarction) and minor CVEs (angina pectoris, significant ventricular arrhythmias, atrial fibrillation or flutter episodes, AV conduction disorders, etc.). A comprehensive preoperative examination was performed, including an extended echocardiography protocol and coronary angiography.Results. In 101 patients (50,05%), various CVEs were identified: 4,0% had major CVEs and 46,05% had minor CVEs and various non-cardiac complications, while perioperative mortality was 2,0%. Most ischemic CVEs, as well as most intracardiac conduction disorders, were registered during the first 3 days after surgery. In contrast, episodes of atrial fibrillation/flutter occurred 2-7 days after the intervention. There were following preoperative examination parameters with the highest prognostic value: history of heart failure, age >65 years, history of myocardial infarction, occlusion of at least one coronary artery, and diabetes.Conclusion. The data obtained indicate the high efficiency of current surgical and anesthetic technologies, which lead to relatively low risk of severe and fatal events. The parameters of the preoperative examination, which determine the increased risk of intervention, are highlighted.

Aim. To evaluate the aortic valve (AV) hemodynamic characteristics after the Ozaki procedure according to echocardiography.Material and methods. The retrospective multicenter study included 277 patients with AV defects who were operated on from January 2017 to June 2022 in five centers in Russia. After the Ozaki procedure, the following endpoints were assessed: immediate echocardiographic results (peak AV gradient, mean AV gradient, AV effective orifice area, aortic regurgitation grade), mid-term clinical (three-year survival rate, three-year freedom from reoperation, three-year freedom from grade ≤2 aortic regurgitation) and echocardiographic results (peak and mean AV gradient, AV effective orifice area, aortic regurgitation grade, AV calcification severity). The median follow-up period was 23 (13-32) months. The mean echocardiography follow-up period was 21±10 months.Results. During the treatment, a decrease in the peak AV gradient was observed from 74±30 mm Hg before surgery up to 12 (8-16) mm Hg one week after surgery, which remained in the mid-term period — 12 (9-15) mm Hg. There was also a decrease in the mean gradient from 40 (27-53) mm Hg before surgery up to 6 (4-8) mm Hg one week after surgery. By the mid-term period, the mean gradient was 6 (4-8) mm Hg. The AV effective orifice area increased from 1 (1-1) cm2 to 2 (2-2) cm2 in the mid-term follow-up period. Three-year survival rate was 90,2%, freedom from reoperation was 95%, freedom from grade ³2 aortic regurgitation was 88%, and no patient had AV calcification.Conclusion. The Ozaki procedure in patients with AV defects has good immediate and mid-term hemodynamic parameters according to echocardiography. However, there remains a need for large randomized controlled trials comparing Ozaki procedure with biological AV replacement.
