Device-related risk of atrial fibrillation after closure of patent foramen ovale: a systematic review and meta-analysis.

The results suggest lower risk expressed by lower rate of incident AF after PFO closure using Amplatzer PFO Occluder when compared with GORE Occluder. However, these findings are derived from secondary analyses and should be scrutinized using appropriate screening tool for AF following PFO closure in adequately powered randomized clinical trial with a head-to-head design that compares the two devices.
