Abstract
Transcatheter closure of a patent foramen ovale (PFO) offers a valuable alternative to surgery in selected patients with presumed paradoxical embolism. Like for all other devices, several complications have been described. Although the majority of these complications are caused by technical problems of the device itself, thrombosis is a relatively infrequent but feared finding, as it may result in recurrent embolic events and persistent neurological deficits. The majority of the complications after implantation are dealt with by surgical removal of the device and subsequent surgical closure of the PFO. The present case report describes biatrial thrombosis of a PFO device that was successfully treated with thrombolytics and GP IIb/IIIa receptor blockers. In stable patients, this pharmaco‐therapeutic approach should be attempted to save the thrombosed PFO device and could therefore offer a valuable alternative to surgical removal of the device.
