Observational
Does elimination of extra-PV triggers improve arrhythmia-free survival in patients with paroxysmal AF and OSA?
Answers are grounded in this paper and cite their sources.
In patients with paroxysmal AF and OSA, who have increased extra-PV triggers, elimination of these triggers improves arrhythmia-free survival.
BACKGROUND: Obstructive sleep apnea (OSA) is associated with atrial remodeling, atrial fibrillation (AF), and increased incidence of arrhythmia recurrence after pulmonary vein (PV) isolation. We aimed to characterize the atrial substrate, including AF triggers in patients with paroxysmal AF and OSA. METHODS AND CONCLUSIONS: OSA is associated with structural and functional atrial remodeling and increased incidence of extra-PV triggers. Elimination of these triggers resulted in improved arrhythmia-free survival.

Anter et al. (2017) conducted an observational in Paroxysmal Atrial Fibrillation and Obstructive Sleep Apnea. Elimination of extra-PV triggers was evaluated on Arrhythmia-free survival (p=0.003). Elimination of extra-pulmonary vein triggers in patients with paroxysmal atrial fibrillation and obstructive sleep apnea resulted in improved arrhythmia-free survival (P=0.003).
