Abstract 9968: Radiofrequency Catheter Ablation for Persistent Atrial Fibrillation Improves Sleep-Disordered Breathing

Abstract only Background: Recent studies have suggested an emerging link between sleep apnea and atrial fibrillation (AF). Radiofrequency catheter ablation is becoming an effective therapeutic option for drug-refractory AF. However, the effect of radiofrequency catheter ablation on sleep-disordered...

Description
Summary:Abstract only Background: Recent studies have suggested an emerging link between sleep apnea and atrial fibrillation (AF). Radiofrequency catheter ablation is becoming an effective therapeutic option for drug-refractory AF. However, the effect of radiofrequency catheter ablation on sleep-disordered breathing has not been sufficiently clarified. Methods: This study included 19 patients (18 men and 1 woman; 62±6 years) with sleep apnea syndrome who underwent radiofrequency catheter ablation for drug refractory, persistent AF. The standard overnight polysomnographic evaluation was performed before and 1 week after the ablation in all patients. The total duration and number of episodes of central or obstructive sleep apnea or hypopnea were analyzed and compared. Results: Among 19 patients, all patients predominantly had obstructive apnea (obstructive apnea index, median 13.8, IQR (interquartile range) 7.1-20.9; central apnea index, 0.2, IQR 0.0-0.5; p
