Case Reports
[Transcatheter closure of patent foramen ovale in patients with platypnea-orthodeoxia].
Platypnea-orthodeoxia is a rare syndrome characterized by the occurrence of dyspnea and hypoxemia on adoption of an upright posture (i.e., orthodeoxia) and by the absence of symptoms and hypoxemia in decubitus. This syndrome is frequently related to patent foramen ovale and right-to-left shunting. ⋯ The echocardiographic diagnosis and closure procedure are discussed. These case reports demonstrate that closure of patent foramen ovale is an effective treatment for platypnea-orthodeoxia.
