Introduction. Non-invasive magnetic resonance-guided focused ultrasound (MRgFUS) is a new neurosurgical treatment option for tremor-dominant Parkinson’s disease (TDPD). Outcomes of ablation with dual targeting of two subcortical nuclei to improve functional treatment results are yet to be explored. Aim. This study aimed to evaluate the safety and e...

Introduction. MRI-guided focused ultrasound (MRgFUS) is approved for management of various movement disorders, primarily essential tremor and Parkinson’s disease (PD), with favorable long-term outcomes in numerous patients worldwide. However, few case studies describe the use of this modality for symptomatic treatment of dystonias that, as the thir...

Backrgound. Magnetic resonance-guided focused ultrasound (MR-FUS) is a new non-invasive technology for the surgical treatment of extrapyramidal movement disorders for such pathologies as essential tremor, Parkinson’s disease, etc. In these cases, the brain is injured and a zone of ischemia is formed. Arterial hypertension (AH) is one of the most co...

Background COVID‐19 limitations have hindered the implementation of new technologies by preventing proctors from coming to the site. We share our first experience of magnetic resonance imaging (MRI)‐guided focused ultrasound (MRgFUS) treatment with an international remote online proctorship, and develop and evaluate the methodology of remote MRgFUS...

Introduction. Cardiovascular disease has been the leading cause of death and disability worldwide for many years. The widespread use of percutaneous coronary intervention has significantly improved clinical outcomes in patients with cardiovascular diseases. However, inflammatory reactions that occur in response to mechanical stretch, endothelial ex...

Objective: To show that effective and safe bilateral MR-guided focused ultrasound (MRgFUS) treatment of essential tremor (ET) is achievable. Material and methods: Four male patients underwent bilateral thalamotomy. Two patients underwent staged thalamotomy, with the ≥12 month interval between operations. Two patients underwent simultaneous bilat...

Introduction. Treatment with MRI-guided focused ultrasound (MRgFUS) is a new, non-invasive surgical technique for treating extrapyramidal movement disorders. This article presents the first use of MRgFUS in Russia for treating patients with essential tremor (ET). Materials and methods. Patients (n = 26; 17 men and 9 women) aged 2182 years (median...

Between December 2014 and March 2021, 144 patients with aortic (Ao) or mitral (Mi) paravalvular leaks (PVLs) were enrolled at 21 sites in 10 countries. Safety data were available for 137 patients, who were included in the safety analysis fraction (SAF), 93 patients with Mi PVLs and 44 patients with Ao PVLs. The full analysis set (FAS) comprised 112...

Background Coronary cameral fistulas (CCFs) are rare congenital malformations consisting of abnormal vascular connections between coronary arteries and cardiac chambers, often incidentally found during cardiac catheterizations. Case summary A 66-year-old female asymptomatic patient, without cardiovascular risk factors and a history of varicose vei...

Background Catheter-based closure has emerged as a less invasive alternative to surgery in high-risk patients with paravalvular leak (PVL) and clinically significant regurgitation with feasibility and efficacy demonstrated in multiple studies. Case summary A 72-year-old female with a past history of long-standing rheumatic heart disease underwent...

Introduction. The use of intravascular imaging techniques, in particular intravascular ultrasound, makes it possible to reduce the number of subsequent revascularisations. The method of optical coherence tomography (ОСТ), due to its high resolution accuracy, makes it possible to establish and assess the edge dissection, stent thrombosis, tissue pro...

In the SFHI (State Funded Healthcare Institution) Republic’s Centre for Cardiology the method of alcohol septal ablation has been introduced in 2015. The paper presents one case of a successful treatment of a patient with hypertrophic cardiomyopathy with left ventricular outflow tract obstruction treated with the use of the method of alcohol septal...

Introduction. The widespread adoption of Artificial Intelligence (AI) technologies forms the core of the so-called Industrial Revolution 4.0.The aim of this study is to examine qualitative changes occurring over the last two years in the development of AI through an examination of trends in PubMed publications. Materials. All abstracts with keyword...

Introduction . Presently there is no unified tactics to treat patients with aberrantly localized coronary arteries of “muscular bridge” type. There are controversial data regarding the benefit of coronary artery stenting due to often stent breakage or perforation of tunneled vessel. There are no major randomized studies regarding this issue. In thi...

Introduction . Pulmonary arterial hypertension (PAH) is a rare disease of unknown etiology, characterized by increased resistance of pulmonary vessels, which leads to right ventriculae heart failure and, eventually, death. At the same time, according to the literature, it has been established that the presence of an atrial septum defect in patients...

Introduction: Modern interventional surgery is one of the most dynamically developing areas of modern medicine. Evidence of this is the bioresorbable stent appearance in its stockpile – intravascular frames, which provide temporary mechanical support and the delivery of cytotoxic substances in the vascular wall during its regeneration. The emergenc...

Introduction. Standard methods used for the diagnosis of strictures in the penile and bulbar urethra (urethrography, multislice computedtomography) do not always provide reliable information on the length of spongiofibrosis, which may sometimes require the adjustment of treatment strategy and the volume of surgery.Objective. We aimed to assess the...

Objective The continuous uninterrupted feedback system is the essential part of any well-organized system. We propose aLYNX concept that is a possibility to use an artificial intelligence algorithm or a neural network model in decision-making system so as to avoid possible mistakes and to remind the doctors to review tactics once more in selected c...

The authors describe the use of optical coherence tomography for the study of coronary blood flow, for the planning and the realization of percutaneous coronary interventions, including stenting, and for the prediction of their results.

A series of studies demonstrated comparability of the incidence rate of major adverse cardiac events (MACE) in the middle-term postoperative period following implantation of last-generation drug-coated stents and biodegradable intravascular scaffolds. It was noted observed that these complications may be associated with malposition and inadequate i...

Objective: To study the results of stenting the left coronary artery trunk and to determine the possibility of using Empira dilatation balloon catheters for kissing dilatation. Subject and methods: The left coronary artery trunk was stented in 47 patients, which constituted 1.39% of the total number of the stented patients. Bifurcation stenting...
