Cryptogenic stroke is the final diagnosis in almost 40% of ischemic acute cerebrovascular events. There is currently no definitive clinical evidence that percutaneous closure of patent foramen ovale (PFO) can prevent the recurrence of stroke or transient ischemic attack (TIA). Identification of the causes of neurologic ischemic syndromes is essential for any strategy intended to prevent the catastrophic consequences of cerebral infarction. Since the initial reports of an unexpectedly high prevalence of PFO in younger patients with cryptogenic stroke in 1988, there has been growing interest and experience in diagnosing and treating these patients, both medically and/or with percutaneous closure, in particular for the potential to eliminate paradoxical embolism via PFO, which is a likely mechanism for stroke in these patients. Selection of the appropriate occluder device is of paramount importance for the success of the procedure. While devices like the Amplatzer PFO Occluder (St. Jude Medical), which, based on the extended follow-up of the RESPECT Trial, was approved by the U.S. Food and Drug Administration last year for recurrent stroke prevention, have become generally accepted as being better than medical therapy for patients needing treatment, concerns remain regarding device- and procedure-related complications. NobleStitch EL is a novel device that offers a simple non-prosthetic implant method of PFO closure without the inherent risks seen with septal occluders: no risk of device embolization, device thrombosis or late erosion, and probably no risk of arrhythmia. Futhermore, there is no material that would hinder future access to the left atrium and no requirement for anti-coagulation.

Abstract
Cryptogenic stroke is the final diagnosis in almost 40% of ischemic acute cerebrovascular events. There is currently no definitive clinical evidence that percutaneous closure of patent foramen ovale (PFO) can prevent the recurrence of stroke or transient ischemic attack (TIA). Identification of the causes of neurologic ischemic syndromes is essential for any strategy intended to prevent the catastrophic consequences of cerebral infarction. Since the initial reports of an unexpectedly high prevalence of PFO in younger patients with cryptogenic stroke in 1988, there has been growing interest and experience in diagnosing and treating these patients, both medically and/or with percutaneous closure, in particular for the potential to eliminate paradoxical embolism via PFO, which is a likely mechanism for stroke in these patients. Selection of the appropriate occluder device is of paramount importance for the success of the procedure. While devices like the Amplatzer PFO Occluder (St. Jude Medical), which, based on the extended follow-up of the RESPECT Trial, was approved by the U.S. Food and Drug Administration last year for recurrent stroke prevention, have become generally accepted as being better than medical therapy for patients needing treatment, concerns remain regarding device- and procedure-related complications. NobleStitch EL is a novel device that offers a simple non-prosthetic implant method of PFO closure without the inherent risks seen with septal occluders: no risk of device embolization, device thrombosis or late erosion, and probably no risk of arrhythmia. Futhermore, there is no material that would hinder future access to the left atrium and no requirement for anti-coagulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
