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.

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.
