Abstract

We present first in Russia experience of interventional treatment of 15 patients (11 men, 4 women, mean age 34.2 +/- 13.9 years) in whom operations of endocardial electrophysiological study (endoEPS) and radiofrequency ablation (RFA) with the help of robotic system of magnetic navigation were carried out because of various disturbances of cardiac rhythm. WPW syndrome and atrioventricular reciprocal tachycardia were verified in 8 patients (in 2 women), ventricular disturbances of rhythm -- in 4 (2 women), atrioventricular nodal reciprocal tachycardia in 3. RFA was effective in all cases what was confirmed in the course of control protocol of endoEPS. Complications related to the conduction of the procedure were not noted. Average duration of the operation was 82 +/- 32 min, mean duration of RF application -- 3.2 +/- 1.1 min. Average duration of fluoroscopic exposure of a patient and physician was 22 +/- 4 min and 3 +/- 1 min, respectively. In 1 patient with WPW syndrome recurrence of anterograde conduction along right anterior-septal accessory atrioventricular pathway (AAP) emerged on the second day after operation. Repeat session with the use of manual technique of irrigation RFA lead to persistent elimination of conduction along AAP. In other cases no recurrences of cardiac rhythm disturbances were observed during 10.2 +/- 1.2 months of follow up in the absence of antiarrhythmic maintenance therapy. The use of robotic system of magnetic navigation for mapping and RFA is highly effective and safe method of treatment of patients with various disorders of cardiac rhythm allowing to lessen significantly radiation burden on the operating physician.
