    Objective was to improve the visualization of anatomy of the heart adapted to the catheter radiofrequency ablation of arrhythmogenic tissues by developing a segmentation algorithm for computed tomography scans, determining the morphological characteristics of the destruction zone, and implementing a method of combining a segmented model with an electro-anatomical card of the heart chamber to improve the safety and efficiency of ablation. The thesis is executed at the State University "NISSKh them. MM Amosova NAMNU "in the department of treatment of arrhythmias with X-ray surgery. Specialized high-tech medical equipment was used for the objectivity of clinical data obtained and used in the work. The object of study - clinical and instrumental and programmed methods of visualization of anatomy of the heart for the effective and safe catheter radiofrequency ablation Subject of study - morphological characteristics of the myocardium and morphometric parameters of the zone of radiofrequency destruction (thickness of the heart wall, location of adjacent anatomical structures, pulmonary veins, esophagus, transmurality of the destruction zone, distance between application points); algorithms for segmentation of anatomical structures in the Ensite Verismo software; combining possibilities in the three-dimensional space of the segmented model and the electro-anatomical card of the chamber of the heart, adapted for further radio-frequency ablation. The results of the work have been introduced into the clinical practice of three electrophysiological operational SF "NISSK them. MM Amosova NAMNU ".
