Pulmonary vein isolation using radiofrequency ablation is the most common method of catheter treatment for atrial fibrillation. Performing this procedure involves use X-ray radiation, which at certain stages an indispensable navigation and visualization intracardiac structures. Approaches to minimize exposure during interventions are attracting increased attention electrophysiology community due potential risks adverse effects ionizing radiation on patients medical personnel. The aim. To...
Introduction. Pulmonary vein isolation (PVI) through radiofrequency ablation (RFA) is the most common method of catheter-based treatment for atrial fibrillation (AF). Electrophysiologists are increasingly focusing on techniques that reduce use X-ray guidance during catheter procedures due to potential risks ionizing radiation patients and medical staff. Methods. The aim this scientific clinical study assess effectiveness safety pulmonary while minimizing exposure optimization...
The work is devoted to research of catheter radiofrequency ablation modes (CRFA) in the treatment heart pathways disease. Lesions sizes myocardial tissue during CRFA have been obtained experiment depending on output generator power, electrode temperature, size tip, duration RF exposure. gives suggestions for optimal modes.
Background. Implementation of conduction system permanent pacing methods in patients with cardiac bradyarrhythmias allows to maintain the physiological sequence excitation and contraction ventricles avoid development heart failure due electrical mechanical dyssynchrony high rates ventricular pacing.
 Case description. A 61-year-old female patient was examined treated at National Amosov Institute Cardiovascular Surgery Academy Medical Sciences Ukraine from January 25 27, 2022 department...
Right ventricular pacing may impair left systolic function in patients with reduced ejection fraction (LVEF).
 The aim. To determine the frequency of pacing-induced cardiomyopathy (PICM) permanent right (at least 90%) and preserved LVEF (≥50%). risk factors for occurrence PICM.
 Materials methods. study included 34 indications whom pacemaker was implanted from 2012 to 2022 (mean follow-up period 44.97 ± 28.45 months). PICM defined as a decrease <45% during regardless clinical...
Objective ‒ to perform the analysis and biophysical substantiation of a new technique catheter radiofrequency ablation (RFA) with high power short duration based on mathematical modeling own clinical data electro-thermodynamic effect RFA myocardium; investigate morphological characteristics myocardium in different areas atrium determine morphometric parameters display electroanatomical model heart zone EnSite Precision navigation system, necessary for effective safe high-power short-duration...
In this article a three-dimensional mathematical model of radiofrequency ablation during open-heart surgery is presented.It was developed to study temperature field distribution into myocardial tissue.This uses an anatomically correct 3D for the left atrium, obtained by magnetic resonance imaging (MRI) processing patient; takes account thermoelectric characteristic differences depending on area electric current application; considers cooling air flow.An ex-vivo experiment pig's heart...
The aim – to determine the frequency of occurrence and describe characteristics pacing-induced cardiomyopathy (PICM) in patients with permanent right ventricular pacing (at least 90 %) preserved left ejection fraction (LVEF) (≥ 50 %).Materials methods. study included 34 indications for who had pacemaker implantation from 2012 2022 (mean follow-up period was 44.97±28.45 months). PICM defined as a decrease LVEF < 45 % during follow-up.Results discussion. incidence this 26 %. average value...
Purpose. This work is devoted to method developing for quantify assessment of the electrodes contact with myocardial tissue during catheter radiofrequency ablation. It will allow perform forecasting destruction efficiency by visualizing them in three-dimensional internal surface heart color spectrum. Methodology. Original automated system developed programming environment Matlab that can application all types catheters and digital map data individual anatomy points derived from...
Review of the problem. The relevance research is need a high-quality imaging left atrium anatomy for effectiveness radiofraquency ablation arrhythmogenic tissue myocardium in real time. For its safety it important to assess attachment esophagus wall heart. Nowadays, methods visualization anatomical structures are dynamically developed on basis data processing DICOM computer and magnetic resonance imaging, including reconstruction 3D Purpose research. task was construct three-dimensional...
Purpose: Today radiofrequency heart ablation is gold standard for the radical surgical treatment of different types rhythm disturbances.The purpose research a comparative analysis monopolar and bipolar electrodes during open surgery (Cox-Maze ablation). Methods: The made based on clinical data mathematical modeling. By use system electro-anatomical mapping zones three-dimensional model left atrium created. Then potential map, which represents amplitude myocardium activity, imposed this...
