OBJECTIVES
In this study, we aimed to evaluate the effect of percutaneous closure of patent foramen ovale (PFO) on the recurrence of stroke and new cardiac arrhythmia using magnetic resonance imaging (MRI) and Holter monitoring.

STUDY DESIGN
Patients with PFO had >1 previous stroke or transient ischemic attack documented with MRI in the first event. PFO with right to left shunt was detected by transesophageal echocardiography (TEE) and transcranial Doppler ultrasound. MRI examinations were performed on patients before and one year after PFO closure was applied. A twenty-four hour Holter monitoring was performed in all patients within 1 month before and 6 months after the procedure.

RESULTS
Percutaneous PFO closure was performed on 47 patients (25 female, mean age: 38.7 years) who had cerebral ischemic events detected by MRI. A year after the procedure, TEE showed that there was no residual interatrial right-to-left shunting. After a 14 month follow-up, no new cerebrovascular event and no new lesion on MRI were recorded. The incidence of arrhythmia did not increase significantly after the procedure on Holter monitoring (p=0.917).

CONCLUSION
One-year clinical and MRI follow-up study of patients with cerebral ischemic events and percutaneous closure of PFO showed no recurrent event and no significant complication associated with the procedure. In addition, Holter monitorization demonstrated that the procedure did not increase the incidence of arrhythmias compared with pre-procedural monitoring.
