It has been a long-running controversy as to whether a PFO should be closed or not to prevent recurrent strokes in patients diagnosed with CS. A paradoxical embolism that is produced through a PFO is hypothesized to be a leading cause of CS, especially in younger patients with low risk factors for stroke. It remains controversial as to which anticoagulation therapy, defined as antithrombin or antiplatelet therapy, is better for patients with CS and a PFO. In addition, surgical and transcutaneous closure of a PFO has been proposed for the secondary prevention of stroke in patients with CS with PFO. Several randomized controlled trials have been conducted in recent years to test whether a PFO closure gives a significant benefit in the management of CS. Three earlier randomized controlled ...
