During the follow-up, graft function was tested using transesophageal echocardiography. The animals were withdrawn at 6 months, and the explanted conduits were assessed histologically.Results: All the conduits were successfully implanted without any surgical complications. All the animals survived throughout the follow-up. By the end of the follow-up period, the pressure gradient increased on five animals’ conduits including one case of mismatch between the conduit and the native pulmonary artery, two cases of distal stenosis, and two case of endocarditis. No significant increase in valve regurgitation or conduit thrombosis was observed during the follow-up. In conduits without dysfunction, the structure of the walls and leaflets was intact. A thin fibrous tissue covered the conduit inner wall with complete surface endothelialization. Neither signs of degeneration or calcification nor inflammatory cells were found in the conduit wall or leaflets. Neointima proliferation without calcium deposits was observed in two distally stenosed conduits. Inflammatory cells consisting of multinucleated macrophages, lymphocytes, and histiocytes were found in the adventitia. There were no inflammatory cells in the media or intima, and the leaflets showed no changes.Conclusion: Diepoxy-treated bovine jugular vein demonstrated acceptable performance, good endothelialization, and low tendency to thrombosis and calcium accumulation in the wall and leaflets.\u0000Received 31 October 2022.

Postoperative acute heart failure is a frequent complication in cardiac surgery, prolonging the length of stay in the intensive care unit and the hospital length of stay.Aim. To develop prognostic risk model of the acute heart failure in the early postoperative period.Methods. This prospective cohort observation study included 121 adult patients who underwent cardiac valve surgery with cardiopulmonary bypass. The need for vasopressor and inotropic support on the first postoperative day was chosen as the primary endpoint. Univariable and multivariable analysis of logistic regression were used to evaluate the influence of preoperative and intraoperative risk factors.Results. Univariable analysis showed risk factors of using vasopressor and inotropic support on the first day after surgical intervention: duration of cardiopulmonary bypass (OR 1.02, 95% CI 1.005–1.030, p = 0.005), aortic cross-clamping time (OR 1.02, 95% CI 1.001–1.030, p = 0.006), Logistic EuroSCORE II (OR 1.16, 95% CI 0.90–1.49, p = 0.03) and tricuspid valve surgery (OR 2.59, 95% CI 1.09–6.10, p = 0.03). As a result of multivariable analysis, the final model included aortic cross-clamping time and Logistic EuroSCORE II.Use of vasopressors and inotropes on the first day after surgical intervention was associated with an increase of the following parameters: duration of mechanical ventilation (p = 0.013), length of stay in the intensive care unit (p = 0.001), hospital length of stay (p = 0.003), and total postoperative blood loss (p = 0.005).Conclusion.

Transcatheter aortic valve replacement is a safe and effective procedure in patients with severe aortic stenosis who are at high surgical risk. One of the most commonly diagnosed complications after transcatheter aortic valve replacement is postoperative complete heart block, requiring in most cases the permanent pacemaker implantation.Aim. The study aims to identify independent prognostic factors of permanent pacemaker implantation after transcatheter aortic valve replacement.Methods. This retrospective study included 336 patients who underwent transcatheter self-expanding aortic valve replacement between 2015 and 2021. 28 patients (8.3%) after procedure required the permanent pacemaker implantation. Patients with a previously implanted permanent pacemaker, surgical aortic valve replacement, transcatheter aortic valve replacement in history and patients after conversion of endovascular intervention to surgical replacement were excluded from the study.Results. The mean age of patients was 75.4 ± 7.4 years. Diabetes mellitus (50.0 versus 28.6%, p = 0.03), baseline right bundle-branch block (32.1 versus 3.9%, p < 0.05), and smaller length of the interventricular membranous septum (5.5 ± 2.2 and 6.9 ± 1.8 mm, p < 0.05) were more common in the permanent pacemaker implantation patient group. The groups were comparable in terms of other clinical, demographic and instrumental characteristics. There were no statistically significant differences between the groups in major procedural complications. Independent prognostic factors of permanent pacemaker implantation were baseline complete right bundle-branch block (OR 21.01, 95% CI 5.86–75.42, p < 0,001), mean transcatheter aortic valve implantation depth below the aortic annulus (OR 1.42, 95% CI 1.16–1.74, p = 0.001) and the length of the interventricular membranous septum (OR 0.7, 95% CI 0.50–0.95, p = 0.02).Conclusion. The frequency permanent pacemaker implantation after transcatheter aortic valve replacement procedure depends on some initial clinical factors, procedural aspects, and postoperative conduction disorders. In this registry, independent prognostic factors of a permanent pacemaker implantation were the baseline complete right bundle-branch block, mean transcatheter aortic valve implantationdepth and the length of the interventricular membranous septum.\u0000Received 19 March 2022.

As long as the design of leaflets is crucial for aortic valve replacement, inaccurate reconstruction can result in failure or stenosis postoperatively.Aim. To analyze average parameters of normal valve leaflets and to assess the correlation between various parameters of a normal aortic valve and personal morphometrics. Methods. The morphometrics of the aortic root were assessed on 54 specimens of the adult heart without any valvular abnormality. We measured following parameters: circumference of the ventriculo-aortic junction and the sino-tubular junction; inter-commissural distance, length of free margin, length of cusp attachment, and height for right coronary, non-coronary, and left coronary aortic leaflets. Results. Based on the average values, the left coronary leaflet is distinguished by the smallest dimensions of the length of free margin and length of cusp attachment. The height of the left coronary leaflet is maximum as compared to the right coronary and non-coronary leaflets, but these differences are minimal (up to 0.2 mm), where the left coronary leaflet is the smallest. Statistically, no significant intergroup difference was found. For all valve sizes, p > 0.05 (inter-commissural distance p = 0.083, length of free margin p = 0.331, length of cusp attachment p = 0.056, height of leaflet p = 0.518). Significant correlations were found between all aortic valve leaflet sizes and the ventriculo-aortic junction and the sino-tubular junction. A weaker correlation was found between all leaflets sizes and the body height.Conclusion. The findings can be used to optimize the leaflet reconstruction and improve the aortic valve function.\u0000Received 9 September 2020. Revised 10 September 2021.

It is aortic valve surgery that implemented minimally invasive technologies most widely. The objective of this systematic review is to present state-of-the-art approaches to minimally invasive aortic valve surgery including patient selection criteria as well as evolution and state-of-the-art of the main surgical approaches. The search strategy covered international databases, such as PubMed, Scopus, Embase, and Web of Science. We used following queries: ‘minimally invasive surgery of the aortic valve’, ‘alternative surgical approaches in aortic valve surgery’, ‘minimally invasive autologous pericardium neocuspidization’. Selection of patients for minimally invasive aortic interventions should consider both the anatomy of the mediastinum and the aortic root as well as cardiac and other comorbidities. Minimally invasive approaches in aortic valve surgery include thoracotomy, partial sternotomy, and endoscopic techniques. Of particular interest is minimally invasive neocuspidization with autologous pericardium. Partial sternotomies are the most routinely used approaches in aortic valve surgery. Their cumulative outcomes allow to compare their efficacy and safety with those of classic sternotomy access within large meta-analyses. Minimally invasive autopericardial neocuspidization and endoscopic interventions on the aortic valve require further surgical experience and clinical outcomes.\u0000Received 17 January 2022.

False aneurysms of smaller arteries located in the hard-to-reach areas are less common. These include aneurysms of the gluteal arteries. This disorder presents a serious problem due to both difficulties in diagnosis and in determining the tactics of surgical treatment. This article presents a case of successfully treated pseudoaneurysm of the gluteal artery in an elderly patient with underlying severe comorbidities. A 73-year-old patient was admitted to the clinic of vascular surgery with complaints of discomfort and pulsating sensation in the right gluteal region during exercise. Ultrasound examination and multislice computed tomography revealed a false aneurysm in the branch of the internal iliac artery measuring 57 × 36 × 46 mm, which was an indication for surgical treatment. The endovascular treatment scoped implantation of the occluder in the superior gluteal artery. The perioperative period was uneventful. According to the scheduled postoperative examination, the patient's condition was satisfactory. Of practical and clinical interest is the fact that the treatment of this disorder is a technically complex and time-consuming process. In this case, the endovascular treatment of aneurysm with an occluder resulted in an adequate therapeutic effect in the patient with underlying severe comorbidities and reduced the risk of perioperative complications.

Over the past 20 years an extensive evidence data accumulated, and most interventional cardiologists around the world have almost completely switched to routine radial access in both elective and emergency procedures, and in the last 5 years, a similar trend has been observed about distal radial access. Non-coronary endovascular interventions go through all the same stages to improve and optimize the approaches, but in a more accelerated way. The aim of this review was to analyze the literature on distal radial access in non-coronary interventions. Currently, according to retrospective studies and single observations, there is a clinical benefit to perform non-cardiac endovascular interventions through distal radial access. However, it is necessary to conduct prospective studies in the context of early, mid-term and long-term outcomes.\u0000Received 16 February 2022. Revised 31 March 2022.

Alternative options for aortic root surgery include Ross procedure and modification of the Bentall – De Bono procedure using autologous pericardium leaflets. This literature review showed topical issues of surgical technique and the results of various modifications of the BioBentall operation, as well as methods of the aortic root repair using autologous materials. The search strategy included the analysis of international (PubMed, Scopus, Embase) and Russian’s databases (Russian Science Citation Index). The BioBentall procedure demonstrates satisfactory early and long-term results comparable to both the classic Bentall – De Bono procedure and valve-sparing techniques. Composite grafts containing frameless bioprostheses seem to be more promising and durable in comparison with stent-grafts, however, given the minimal amount of publications directly comparing these techniques, further study of this hypothesis is necessary. Total xenopericardial conduits have demonstrated higher rates of degradation and are currently not recommended for use, as demonstrated in most foreign studies. Modified Ross procedure shows excellent hemodynamic outcomes in the long-term follow-up, however, the literature data regarding its applicability in a cohort of patients with proximal aortic aneurysms are limited. The combination of the Bentall – De Bono procedure and autopericardial neocuspidization seems to be a promising and cost-effective method, however, this approach requires a clinical assessment, which results have not been yet published.\u0000Received 26 February 2022.
