Abstract
Platypnea–orthodeoxia syndrome (POS) is a rare clinical disorder characterized by dyspnea caused by the upright position and relieved at recumbent position. Few cases of POS and stroke were reported in literature, and the association between stroke and POS with evidence of patent foramen ovale (PFO) is rare. Stroke may occur in patients with cardiac shunt who undergo contrast echocardiography. We present a patient with POS who experienced transitory ischemic attack (TIA) most likely caused by injection of agitated saline microbubbles during screen for PFO. No case report of TIA/stroke during contrast echocardiography in patients with POS has previously been published.
