The article considers the problem of carrying out electrophysiological procedures without using X-ray. The work uses the results of PVI at the same time with ablation of CTI with system three-dimensional navigation, without using fluoroscopy. The study was conducted in 2019. The study included 32 patients. Average age 63 ± 3 years. The procedures were carried out using a navigation system. Puncture of the interatrial septum and control of the position of the instruments was carried out using intracardiac ultrasound. The first step of the procedure was pulmonary vein isolation, followed by ablation of the CTI. Follow-up period was 12 months. No cases of typical atrial flutter were diagnosed. 6 patients had AF episodes 4 months after surgery. Conclusion: Conducting a combined operation, namely ablation of CTI with pulmonary vein isolation, without the use of fluoroscopy, is possible and safe.
