Abstract
Paradoxical embolism is a risk factor for cryptogenic stroke in young adults, and can be primarily attributed to the presence of patent foramen ovale (PFO). Although contrast echocardiography may facilitate diagnosis, it would be difficult to distinguish a PFO from a pulmonary arteriovenous fistula (PAVF), which could also result in paradoxical embolism. We report a 46-year-old woman with recurrent ischemic stroke, who was scheduled for PFO closure because of a right-to-left shunt detected by contrast echocardiography. The diagnosis turned out to be a PAVF confirmed by angiography. Thereafter, coil embolization of this PAVF was performed successfully.
