Key result
Specific clinical, instrumental, and electrophysiological features were found to be prognostically significant for the development of atrial fibrillation after cavotricuspid isthmus ablation.
Observational (n=209)
The study identifies prognostically significant clinical and electrophysiological features, along with a modified induction test, for predicting atrial fibrillation after cavotricuspid isthmus ablation for typical atrial flutter.
May aid post-CTI ablation AF risk stratification; hypothesis-generating and requires prospective validation.
The article presents the clinical, instrumental and electrophysiological features of patients who develop atrial fibrillation after cavotricuspid isthmus ablation in 209 patients with typical atrial flutter. Taken together, these features make up a peculiar clinical, instrumental and electrophysiological portrait of patients with post-ablative atrial fibrillation. Comparative analysis of these parameters was made, and it was found that some of them are prognostically significant. Also, we describe the technique of modified intraoperative electrophysiological test of atrial fibrillation induction in patients with typical atrial flutter. We investigated the role of this technique in the occurrence of post ablative atrial fibrillation.

Steklov et al. (2018) conducted an observational in Typical atrial flutter (n=209). Cavotricuspid isthmus ablation was evaluated on Development of post-ablative atrial fibrillation. Specific clinical, instrumental, and electrophysiological features were found to be prognostically significant for the development of atrial fibrillation after cavotricuspid isthmus ablation.
