Efficacy of different devices for transcatheter closure of patent foramen ovale assessed by serial transoesophageal echocardiography and rates of recurrent cerebrovascular events in a long-term follow-up

Closure of patent foramen ovale (PFO) is non-inferior to medical treatment for patients with cryptogenic stroke. Results in randomised trials might be based on the different types of used occluders. We determined residual shunting with serial contrast transoesophageal echocardiography (cTEE) and evaluated rates of recurrent cerebrovascular events in a long-term follow-up.cTEE was repeated three and 12 months after PFO closure using AMPLATZER...
