However, rupture of this aneurysm can lead to serious consequences for the patient's health. For the surgical treatment, both microsurgical and endovascular methods are used. A 19-year-old patient was admitted to our hospital on day 21 after suffering a subarachnoid-ventricular hemorrhage from an aneurysm of the right posterior meningeal artery. On admission, the patient complained of a headache. Cerebellar symptoms were noted in the neurological status. According to digital subtraction angiography, the patient had an anastomosis between the posterior meningeal artery and the hypoplastic p1-segment of the right posterior inferior cerebellar artery distal to the aneurysm. Endovascular method was used to occlude the aneurysm with a detachable coil. The patient was discharged on the third day with total regress of neurological symptoms. Control cerebral angiography 3 months later showed thrombosis of the aneurysm with the supporting segment of the parent artery, as well as restructuring of the main blood flow of this basin through the previously hypoplastic posterior inferior cerebellar artery. In the literature, we found only 9 such cases. Endovascular treatment of this pathology is, in our opinion, effective and safe, and the presence of an anastomosis distal to the aneurysm made it possible to avoid disruption of blood supply in the vascular basin of the affected artery.Received 21 September 2021.

Currently, researchers focus on fundamental and clinical relationships between circadian rhythms and carcinogenesis, and one of the key problems is the potential of melatonin as an agent capable of interfering with the molecular processes of formation and maintenance of the viability of malignant tumors. An equally important problem is the potential of melatonin in terms of using its physiological properties for the prevention and accompanying therapy of undesirable effects of the main treatment in oncological practice, which is emphasized in this review. The purpose of this review is an unbiased study of the prospects for the multidirectional use of melatonin both as a direct antitumor agent and as a component of complex therapy of concomitant adverse events associated with tumor and the treatment. Based on a detailed analysis of original scientific articles and scientific reviews in the PubMed search system, as well as peer-reviewed Russian journals, authors have made an attempt to characterize the current state of melatonin in oncology based on principles of evidence-based medicine. Authors also suggests and justify key prospects for use of melatonin in oncology practice and the range of studies necessary to clarify its properties and place in the combined therapy of malignant neoplasms.Received 9 July 2021.

In most cases, patients with secondary mitral regurgitation have a rather poor prognosis, for example, about 50% of patients are at high risk of surgery or are inoperable, while mortality within 1 year without surgery is 57%. The tactics of treating these patients is the subject of much debate. According to the American Association for Thoracic Surgery (Ischemic Mitral Regurgitation Consensus Guidelines Writing Committee), mitral valve reconstruction is accompanied by a large number of relapses of mitral insufficiency in the long term after surgery, and mitral valve replacement is characterized by high mortality (≥ 13%). With the optimal selected conservative therapy (Guideline-directed medical therapy), in most patients, there is no significant improvement in their condition. Since the 2000s the development of methods of interventional influence on the mitral valve for the treatment of such patients is underway. In the 2010s, interventional treatment techniques began to be widely used, and recommendations for their use began to be developed. In some cases, the results of using the techniques are superior to open surgery. Is it possible to say that the problem of treating patients with functional mitral insufficiency of high operative risk has been solved? In order to answer this question, a literature review was carried out on the interventional treatment of secondary mitral regurgitation using the \"edge-to-edge\" technique.We used PICO strategy (Patient, Intervention, Comparison, Outcome) for searching articles. A systematic search for information on the research topic was carried out in the PubMed and Google Scholar databases using search queries, keywords, and logical operators AND, OR. Key words: mitral regurgitation, functional mitral regurgitation, chronic mitral regurgitation, MitraClip, percutaneous mitral repair, mitral insufficiency, mitral valve, Edge-to-Edge repair. In the initial selection, 1,180 publications were received. After analyzing the titles and abstracts, 94 articles were selected, and full-text copies were studied.

Ball-valve prostheses are made of long-living and hard-wearing materials; however, these properties confer significant disadvantages resulting from the large dimensions and weight, increased pressure gradient and risk of valve thrombosis and systemic embolism. With the advent of more advanced disk structures, the use of ball-valve prostheses was ended.In Russia and other counties, the scientific literature shows an increase in reoperation after implantation of ball-valve prostheses over the long-term, which is associated with the occurrence of another valve defect. The need to replace a functioning ball-valve prosthesis with a modern mechanical or biological prostheses during surgery for another valve is still controversial.We present a case report of a 55-year-old patient with rheumatic mitral stenosis and functional insufficiency of the tricuspid valve, who underwent repeat surgery 38 years after implantation of a ball-valve prosthesis in the aortic position. From the echocardiography findings, the peak transmitral gradient was 16 mm Hg, the average gradient was 5.5 mm Hg, the area was 1.3 cm2 and regurgitation was third-degree. On the tricuspid valve, there was third-degree regurgitation.Adequate hemodynamic parameters of the ball-valve prosthesis (the maximum blood flow rate was 2.65 m/sec, the peak gradient was 30 mm Hg, the average gradient was 18 mm Hg and there was no regurgitation) and the absence of valve-dependent complications enabled us to perform mitral prosthetics and tricuspid valve plastic surgery without replacing the aortic prosthesis, which reduced the operation time and decreased the risk of complications.The patient was examined two years later. The patient’s active lifestyle and adequate hemodynamic parameters proved the rationality of our treatment policy.The reported case indicates that mitral valve defect that develops a long time after aortic valve prosthetics can be treated surgically without the replacement of a ball-valve prosthesis in the case that it has good function.Received 25 July 2021.

Comparative assessment of the surgical strategies and one-year results of coronary artery bypass grafting (CABG) in patients with and without target artery distal calcinosis.Methods. A prospective study from January 2017 to October 2018 included 462 patients with coronary artery disease. All patients underwent CABG. Groups were formed according to coronary angiography data. Group 1 — patients with target artery distal calcinosis (n = 108). Group 2 — patients without any marks of coronary calcification (n = 354). To minimize systematic errors and maximize their comparability, computer correction was performed using propensity score matching (group 1, n = 106, group 2, n = 106). Intraoperative data and one-year outcomes were analyzed and compared.Results. Following the strategy for complete revascularization, we had to form a greater number of distal anastomosis in group 1 due to severe coronary atherosclerosis. The index of revascularization was higher in group 1 (4.4 ± 0.7 and 3.9 ± 0.8, p = 0.001). We registered a higher frequency of using prolonged patch-angioplasty (21.7 versus 1.8 %, p < 0.001), anastomosis with artery diameter < 1.5 mm (33.9 versus 16 %, p < 0.003), coronary artery endarterectomy (13.2 versus 0.9%, p < 0.001) in patients with coronary artery calcinosis. As well as the creation of composite grafts, such as Y-graft (33 versus 8.5 %, p < 0.001) and sequential graft (13.9 versus 5.7 %, p = 0.03) were higher in group 1. The use of adjunctive surgical techniques in the main group significantly increased the duration of cardio-pulmonary bypass and aortic cross-clamp time. The primary endpoints – coronary ischemic events – angina recurrence (10.3 versus 6.3 %, p = 0.307), myocardial infarction (3.1 versus 2.1 %, p = 0.654), the need for re-revascularization (3.1 versus 1 %, p = 0.318) were comparable in 1 year after surgery. Overall mortality was relatively low in both groups.Conclusion. CABG in patients with target artery distal calcinosis is associated with similar one-year outcomes compared to CABG in patients without coronary artery calcification. The positive results of CABG in patients with target artery distal calcinosis indicate the benefits of complete myocardial revascularization, despite the long duration and complexity of interventions.Received 29 September 2021.

AF increases overall mortality by 1.9 times and the risk of stroke by 5 times, leads to disability among the working-age population, and reduces the quality of life.Pulmonary veins isolation is the main approach in the treatment of AF symptomatic patients who are resistant to antiarrhythmic therapy. However, the use of this technique is associated with the need for long-term use of fluoroscopy and monitoring of the contact force of the ablation catheter with the heart tissue for an effective and safe exposure on the arrhythmia substrate. In addition, the complication rate can reach up to 5% even when using non-fluoroscopic navigation systems.Over the past decade, robotic magnetic navigation was established as a safe and effective technology in the treatment of patients with different cardiac arrhythmias. The advantages of this technology are the flexibility and mobility of the ablation catheter to reach difficult areas during ablation procedure, as well as high efficiency and safety, with a low fluoroscopy exposure time. This review analyses the current literature and documents the experience of using robotic magnetic navigation for the treatment of patients with different forms of AF. We conducted searches on Scopus, Web of Science databases and PubMed.The reviewed studies demonstrated that the use of robotic magnetic navigation is a safe and highly effective method of treating patients with AF. It also helps to reduce the time of fluoroscopy during ablation procedure.Received 26 August 2021. Revised 21 September 2021.

Atypical localization of the focus of ventricular arrhythmias is a rather difficult group for invasive mapping and subsequent radiofrequency ablation. Invasive electroanatomical mapping, multipolar electrophysiological electrodes in combination with electrophysiological study for searching an early zone of arrhythmia focus, and substrate mapping, are aimed to identifying critical areas of the arrhythmia contour. However, there are still situations in which arrhythmia cannot be eliminated, despite the use of these systems. The method of superficial non-invasive mapping of the heart seems to be relevant, which makes it possible to estimate the volume of surgery and select the necessary technology to eliminate arrhythmias.Aim. To compare the effectiveness of interventional treatment of patients with ventricular arrhythmias of atypical localization with and without the use of superficial non-invasive mapping.Methods. The study included 40 patients with ventricular arrhythmias of rare localization. The patients were divided into two groups. Group I included 21 patients who underwent non-invasive superficial and invasive electrophysiological cardiac mapping. Group II included 19 patients who underwent invasive electrophysiological cardiac mapping.Results. Over a follow-up period of 12 months, the freedom from arrhythmia in group I was 76%, in group II — 61%. The total operation time, duration and dose of fluoroscopy were less in group I compared to the group II.Conclusion. The study results demonstrated that the method of non-invasive surface mapping of the heart is highly effective in ventricular arrhythmias of atypical localization. The time of radiofrequency ablation, interventional intervention, fluoroscopy is lower with the use of superficial non-invasive mapping, compared with the control group.Received 13 July 2021.
