Endovascular occlusion of patent foramen ovale as antiarrhythmic treatment of atrial fibrillation.

The study published in the Journal of Interventional Cardiac Electrophysiology explores the impact of endovascular occlusion of patent foramen ovale (PFO) as an antiarrhythmic treatment for atrial fibrillation (AF). The research involved a case-control study comparing patients with and without PFO who underwent AF ablation. Results indicated that PFO closure following AF ablation significantly reduced the risk of AF recurrence, suggesting that PFO may be a potential risk factor for AF. The study highlights the potential benefits of a combined treatment approach involving ablation and PFO closure in managing AF. [Extracted from the article]
