Percutaneous patent foramen ovale closure: outcomes with the Premere and Amplatzer devices.

Background: Transcatheter closure of patent foramen ovale (PFO) has rapidly evolved as the preferred management strategy for the prevention of recurrent cerebrovascular events in patients with cryptogenic stroke and presumed paradoxical embolus. There is limited outcome data in patients treated with this therapy particularly for the newer devices.

Methods: Data from medical records, catheter, and echocardiography databases on 70 PFO procedures performed was collected prospectively.
