Abstract:Platypnea-orthodeoxia is an uncommon syndrome characterized by positional dyspnea and hypoxia when upright that improves with lying down. We present a 75-year-old man with platypnea-orthodeoxia in the setting of a patent foramen ovale (PFO) and a 2.1 cm highly mobile atrial septal aneurysm with 2 cm bowing. Prior reports have established the use of three-dimensional echocardiography to facilitate percutaneous closure of PFO and atrial septal defect, but its use in patients with platypnea-orthodeoxia is unclear… Show more
In our series of patients, the closure rate was dependent on PFO morphology more than occluder size and type. An adjunctive device was implanted in selected cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
