Key result
Variant pulmonary vein anatomy and LAVI >48.5 linked to AF recurrence after RFCA.
Why the study?
Although multiple predictors of AF ablation success are known, the influence of pulmonary vein anatomy on AF recurrence after radiofrequency catheter ablation required assessment.
Does variant pulmonary vein anatomy increase the risk of atrial fibrillation recurrence after radiofrequency catheter ablation in patients with paroxysmal or persistent AF?
Population
80 patients with paroxysmal or persistent AF undergoing RFCA
Comparison
Variant PV anatomy vs regular PV anatomy
Design
Observational cohort study
Follow-up

Variant PV anatomy and larger LAVI were associated with AF recurrence after RFCA; hypothesis-generating for risk stratification, prospective validation required.

Does variant pulmonary vein anatomy increase the risk of atrial fibrillation recurrence after radiofrequency catheter ablation in patients with paroxysmal or persistent AF?
Variant pulmonary vein anatomy and increased left atrial volume index are independent predictors of atrial fibrillation recurrence following radiofrequency catheter ablation.
Istrătoaie et al. (2019) conducted a cohort in Paroxysmal or persistent atrial fibrillation (n=80). Radiofrequency catheter ablation was evaluated on Atrial fibrillation recurrence. Variant pulmonary vein anatomy and left atrial volume index >48.5 mL/m2 (p=0.006) were independently associated with atrial fibrillation recurrence after radiofrequency catheter ablation.
