Patent foramina ovale (PFO) are small defects within the atrial septum that may play a role in paradoxical embolism, stroke and migraines. The relationship between PFO and atrial fibrillation (AF) has not been formally studied. We prospectively studied patients with a history of AF, versus those without (controls), in order to compare PFO prevalence among them.
