In patients with CTI-F, as a result of ablation, sinus rhythm was restored in 23 of 30; in 7 patients CTI-F was transformed into another type of atrial reentry. Of 23 patients with restored sinus rhythm, 6 patients experienced another type of atrial reentry induced by rapid pacing. Non CTI-F terminated during ablation and was non-inducible in 13 of 14 patients; in 3 patients rapid pacing induced non-sustained atrial fibrillation and in one – CTI-F, which was success-fully eliminated. Overall, acute success rate was 98%, with 100% for CTI-F and 96% for non CTI-F. There were 6 recurrences during the follow-up: in 3 cases it was AT previously ablated; in 3 cases – a different type of AT. All of them were successfully ablated after the second procedure. AT catheter ablation in patients with CHD is feasible, safe, with high success rate.</p&gt;}, number={1 (34)}, journal={Ukrainian Journal of Cardiovascular Surgery}, author={Stychynskyi, A.
