On the basis of the department of surgical treatment of complex cardiac rhythm disturbances and pacing of the Pirogov Center for the first time an operation — epicardial radiofrequency catheter ablation (RFA) in a patient with Brugada syndrome and recurrent episodes of polymorphic ventricular tachycardia (VT) was performed. The operation was performed using a three-dimensional navigation mapping system (CARTO 3, Biosense Webster).

The operation was performed on patient B., 41, with a previously implanted cardioverter-defibrillator for Brugada syndrome. The duration of the intervention was 6 hours. In the early postoperative period, no ventricular cardiac rhythm disturbances were recorded. The patient was discharged from the hospital on the fourth day of hospitalization.

Ventricular tachycardias are often malignant in nature and are the leading cause of sudden cardiac death, from which 200-250 thousand people die each year in the Russian Federation. VTs not only affect life expectancy, but also significantly reduce its quality and lead to disability. Brugada syndrome is a genetically determined disease that leads to death at a young age.

Currently, the standard for the prevention of sudden cardiac death in ventricular arrhythmias is the installation of an implantable cardioverter defibrillator (ICD). Despite the effectiveness of ICD, catheter RFA is by far the most radical and promising method for treating VT. In Brugada syndrome, epicardial RFA is required using subxiphoidal percutaneous access and three-dimensional navigation mapping systems, which can accurately identify and eliminate the sources of arrhythmias. In the future, under the conditions of the Pirogov Center, it is planned to continue the implementation of such procedures, which are not yet implemented on the territory of the Russian Federation.
