title: Hypoxemia related to right-to-left shunting through a patent foramen ovale: successful percutaneous treatment with the CardioSeal device.
abstract: Hypoxemia related to right-to-left shunting through a patent foramen ovale (PFO) is not rare. It can be observed in correlation with a specific situation such as pneumonectomy and can occur even with normal pulmonary pressure. This article reports the experience of 12 patients in which a transcatheter closure with the CardioSeal device was done successfully. Clinical improvement is often obtained, despite incomplete occlusion of the defects. The author demonstrated that transcatheter closure of PFO can be performed safety and should be considered as an efficient alternative to surgery in cyanotic patients with PFO.
