[Platypnea-orthodeoxia syndrome: case report].
We report the case of an 80-year-old woman with symptomatic postural hypoxaemia caused by a right-to-left shunt through a patent foramen ovale. The hypoxaemia was enhanced by the supine position and disappeared in upright position. Potential mechanisms underlying postural variations of the shunt seemed to be similar to those describe in platypnea-orthodeoxia syndrome. Patient became asymptomatic after shunt resolution.
