Key result
Ischemic heart disease linked to ~52% lower intraoperative AF-to-sinus conversion vs idiopathic AF.
Why the study?
Catheter ablation outcomes vary with cardiovascular comorbidities, and intraoperative rhythm changes may indicate long-term effectiveness or guide additional procedural steps.
Does concomitant ischemic heart disease affect intraoperative atrial rhythm dynamics during catheter ablation for atrial fibrillation?

Does concomitant ischemic heart disease affect intraoperative atrial rhythm dynamics during catheter ablation for atrial fibrillation?
Concomitant ischemic heart disease in patients undergoing AF ablation is associated with different intraoperative rhythm dynamics, including a higher incidence of typical atrial flutter requiring additional ablation.

Ischemic heart disease was associated with lower intraoperative conversion; leaves open whether tailored ablation strategies improve outcomes in this subgroup.
Atrial fibrillation is a rhythm disorder with an extensive etiology and not fully understood pathogenesis. Catheter ablation is an effective way to control the rhythm of atrial fibrillation. The results of catheter ablation differ in patients with various comorbidities of the cardiovascular system. Intraoperative changes in the atrial rhythm can be a criterion for the long-term effectiveness of the operation or determine the need for additional effects. Aim: To assess intraoperative changes in atrial rhythm during catheter ablation of atrial fibrillation in patients with concomitant pathology of the cardiovascular system. Methodology and research methods. The results of catheter ablation of 451 patients with paroxysmal and persistent atrial fibrillation were analyzed retrospectively for the period from 2016 to 2017. After clinical and anamnestic data analysis, 151 patients with primary isolation of the pulmonary veins were selected. Depending on the concomitant pathology of the cardiovascular system, patients were divided into 3 groups: group 1 – with idiopathic atrial fibrillation, group 2 – atrial fibrillation in combination with isolated essential arterial hypertension and group 3 – atrial fibrillation in combination with ischemic heart disease. Results. In patients with idiopathic atrial fibrillation, relief of atrial fibrillation with sinus rhythm preservation until the end of surgery was more often observed than in patients with ischemic heart disease (22% vs. 10,6%, р = 0,021). In patients with ischemic heart disease, typical atrial flutter was much more common and there was a need to perform radiofrequency ablation of the cavothricuspid isthmus in addition to isolation of the pulmonary veins (47,9% vs. 18,8% 1 Group 1, р = 0,005, and 24,7% in Group 2, р = 0,01). Conclusions. The concomitant pathology of the cardiovascular system in patients affects the dynamics of the atrial rhythm during catheter treatment of atrial fibrillation and may take into account the definition of intraoperative tactics.

Gorev et al. (2024) conducted a cohort in Atrial fibrillation (n=151). Ischemic heart disease vs. Idiopathic atrial fibrillation was evaluated on Relief of atrial fibrillation with sinus rhythm preservation until the end of surgery (p=0.021). Patients with ischemic heart disease had a lower rate of intraoperative transition from atrial fibrillation to sinus rhythm compared to those with idiopathic atrial fibrillation (10.6% vs 22%, p=0.021).
