Title : Trans-catheter PFO Closure;clinical indications, technique and midterm follow up,Case series
Implantation of a PFO-occluding device may reduce the risk of recurrent stroke or transient ischemic attack compared with medical therapy in patients with cryptogenic stroke. However, there is a debate about the indication for closure and the power of secondary prevention by the implanted device. Our aim is to clarify the indications for PFO closure, explaining our protocol to document the degree of the pathogenicity of PFO as a source of right to left shunt, depending of both transoesophageal echocardiographic study and transcranial Doppler. Classification of PFO according to its shape and the implication of the morphology on the chosen device. Demonstrating by multiple movies that PFO could be a simple pathology or a complex one. Explaining the techniques of measurement of the defect and the device implantation during the presentation. Follow up regarding recurrent cerebral events or complication related to the device implantation.
