Patent foramen ovale (PFO) is a flaplike opening in the fossa ovalis; between the septum primum and secundum. It is highly prevalent with approximately 25% of the population having a PFO. It is usually asymptomatic but can rarely cause paradoxical embolism leading to stroke and/or significant right to left shunting causing hypoxia. The complications of PFO closure with a percutaneous device include embolization, cardiac perforation, and thrombosis. These are all early complications. We describe the case of a patient with a history of PFO closure who had device thrombosis 3 years after implantation. Management includes anticoagulation with warfarin. Repeat cardiac imaging to document the resolution of thrombosis is recommended.
