Does transcatheter patent foramen ovale closure increase the long-term risk of atrial fibrillation or flutter?
Transcatheter PFO closure does not appear to carry a substantial long-term risk of atrial fibrillation beyond the initial peri-procedural period.
Patent foramen ovale closure was not associated with any substantial increased long-term risk of developing AF beyond the well-known procedure-related short-term risk.
Skibsted et al. (Sat,) studied this question.
