This is a prospective, bicentric, observational cohort study which will be performed in University hospital center of Montpellier and Nîmes The study will include all consecutive patients, admitted for a percutaneous PFO closure after an ischemic stroke (IS) or a transient ischemic attack (TIA) of cryptogenic origin, or after the occurrence of a decompression illness during scuba diving. Patients eligible for the closure of a FOP in prevention of the recurrence of stroke or TIA of cryptogenic origin, was systematically evaluated for exclusion of supraventricular arrhythmia in accordance with international recommendations. This evaluation included a 12-lead ECG as well as an extended electrocardiographic monitoring lasting more than or equal to 24 hours (most frequently, performing a 72-hour ECG Holter). All patients previously has a transesophageal ultrasound (TEE) allowing to retain the diagnosis of PFO, to assess the presence or not of an atrial septum aneurysm (ASA) associated with PFO and to quantify the right to left shunt thanks to a contrast test potentiated by a Valsalva maneuver. Exclusion criteria included interatrial defect with left to right and others indications for PFO closure that cryptogenic stroke or decompression illness. Indication of PFO closure is always validated by a cardio neurological team. The primary objective of the study was incidence of AF defined as an irregular rhythm without discernible P waves lasting at least 30 seconds on ECG monitoring during the 6-month follow-up. The secondary objectives were to evaluate the characteristics of the supra-ventricular arrhythmias (delay in onset, duration, recurrent nature), incidence of others arrhythmia, symptoms, and prognostic implications of AF (hospitalization , need of curative anticoagulation, need for cardioversion and occurrence of neurological accident documented by imagery (ischemic stroke or TIA). The investigators also evaluated risk factors for occurrence of arrhythmia. A total of 100 patients included during 1 year is expected
