Platypnea-orthodeoxia: management by transcatheter buttoned device implantation.
Dyspnea and arterial desaturation on upright position in elderly subjects is described as platypnea-orthodeoxia syndrome (POS) and in some patients it is due to right-to-left shunt across the atrial septal defect (ASD)/patent foramen ovale (PFO). Surgical closure of ASD/PFO has been the only available treatment option. Buttoned device has been used for occlusion of ostium secundum ASD, PFO associated with presumed paradoxical embolism and cerebrovascular accidents and ASD/PFO in association with other congenital heart defects causing right-to-left shunt. ⋯ Follow-up of 1-36 months (median 12 months) revealed persistent improvement of symptoms. Buttoned device occlusion of ASD/PFO to relieve hypoxemia of POS is feasible, safe, and effective and is an excellent alternative to surgery. Cathet Cardiovasc Intervent 2001;54:77-82.

Case ReportsSimultaneous transcatheter occlusion of two atrial baffle leaks and stent implantation for SVC obstruction in a patient after Mustard repair.
A 19.5-year-old patient after Mustard operation was found to have baffle leaks and obstruction. This patient underwent successful device closure of the leaks using the Amplatzer device and stent implantation with complete resolution of the symptoms. Cathet Cardiovasc Intervent 2001;54:72-76.
