DEVELOPMENT OF APPROACHES TO IMPROVEMENT OF LATE OUTCOMES OF THE "LABYRINTH" ATRIAL RADIOFREQUENCY FRAGMENTATION BASED ON THE EXPERIENCE OF 200 PROCEDURES
To develop approaches to the “labyrinth” radiofrequency atrial fragmentation, reveal predictors of early sinus node dysfunction, and develop approaches to its prevention, 200 patients aged 50.1±10.2 years, including 186 patients with acquired heart disease and 14 subjects with congenital heart disease, were examined and surgically treated.
