radiofrequency ablation, electrode contact with myocardium, efficiency, automated systemAbstract
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 to perform forecasting destruction efficiency by visualizing them in three-dimensional internal surface of the heart in the color spectrum.Methodology. Original automated system is developed in the programming environment Matlab that can work with application of all types of catheters and digital map data of individual anatomy of the heart and destruction points derived from the electro-anatomical mapping system Ensite Velosity NavX (St. Jude medical, USA). The construction of three-dimensional model of the heart is performed and the radiofrequency destruction points are superimposed on it in a color spectrum corresponding to different distances electrode to myocardial tissue during ablation.
Results and practical value. The assessing method of electrodes contact with myocardial tissue during catheter radiofrequency ablation is confirmed its accuracy and efficiency in clinical practice. It is introduced in State Institution "M.M. Amosov National Institute of Cardiovascular Surgery at NAMS of Ukraine" for control and predicting of tissue destruction effectiveness in the left atrium around pulmonary veins and isthmus between the veins and valves to block the spread of potential that lead to fibrillation and atrial flutter.
