Filter by:Closure of Patent Foramen Ovale with the AMPLATZER® PFO OCCLUDER in patients with at least two cryptogenic strokes due to presumed paradoxical embolism through a patent foramen ovale and who have failed conventional therapy.
A patent foramen ovale (PFO) is found more frequently in patients with an ischemic stroke than in control subjects. Therapeutic options to prevent stroke recurrence include antiplatelet drugs, oral anticoagulants, and transcatheter closure of the foramen. However, there are no published studies showing convincingly the superiority of any one of these strategies in preventing stroke recurrence. The aim of this randomized clinical trial is to assess whether chronic anticoagulation on the one hand and transcatheter on the other hand are superior to chronic antiplatelet therapy in preventing stroke recurrence.
The purpose of this study is to evaluate migraine headache frequency in subjects who have migraine with aura and a patent foramen ovale (PFO, a slit-like opening between the right and left upper chambers (atria) of the heart which normally closes at or soon after birth) who are randomized to either undergo closure of the patent foramen ovale or continue with standard medical management.
The purpose of this study is to investigate whether percutaneous Patent Foramen Ovale (PFO) closure, using the AMPLATZER PFO Occluder, is superior to current standard of care medical treatment in the prevention of recurrent embolic stroke.
The Purpose of this study is to evaluate the impact of percutaneous closure of a patent foramen ovale (PFO) (a hole in the heart), using the AMPLATZER PFO Occluder, on the incidence of migraine headaches.
The primary objective of this study is to demonstrate the safety and performance of the PFx Closure System when utilized for patients with PFOs suffering from cryptogenic stroke, transient ischemic attack, migraine or decompression illness.
The objective of the study is to investigate the safety and effectiveness of PFO closure with the BioSTAR Septal Repair Implant System in a population of patients that have refractory migraine (with aura) and who have failed medications.
This is a prospective multicenter clinical study to evaluate the safety and effectiveness of an intracardiac septal closure device in patients with atrial septum defect (ASD) and patent foramen ovale (PFO).
The primary objective of the study is to determine whether the STARFlex® septal closure system will safely and effectively prevent a recurrent embolic stroke/transient ischemic attack (TIA) and mortality in patients with a PFO and to demonstrate superiority of the STARFlex® device compared to best medical therapy.
The primary objective of this study is to demonstrate the safety and efficacy of the PFX Closure System when utilized for patent foramen ovale (PFO) in patients suffering from cryptogenic stroke (undetermined cause of stroke), transient ischemic attack (brief neurological dysfunction), migraine or decompression illness.
