Late Atrial Thrombus Formation After Percutaneous Patent Foramen Ovale Closure

Late thrombus formation is a rare complication associated with patent foramen ovale (PFO) closure devices. We report the case of an incidental discovery of large thrombi in both atria 9 months after percutaneous PFO occlusion that required cardiac surgery for thrombi removal.
