A case report of platypnea-orthodeoxia syndrome: an interplay of pressure and blood flow.

ABSTRACT:

Background

Platypnea-orthodeoxia syndrome is a rare condition characterized by onset or worsening of dyspnoea with orthostatism (platypnea) and arterial desaturation (orthodeoxy) that is relieved by returning to a recumbent position. An acute event causing a change in the pressure relationships inside the cardiac chambers can lead to the diagnosis of a previously undiagnosed cardiac anomaly, as the following case illustrates.

Case summary

A previously asymptomatic 80-year-old female patient was admitted in our hospital with a sudden onset ischaemic stroke. Initial evaluation, including 12-lead electrocardiogram and transthoracic echocardiogram, was unremarkable.
