|---|
Patent foramen ovale (PFO) is a relatively common congenital condition which has been implicated in cryptogenic stroke as a result of paradoxical thromboembolism by right-to-left shunting. Many studies have demonstrated that transcatheter PFO closure significantly reduced the incidence of recurrent strokes in a small group of high-risk patients with PFO and atrial septal aneurysm compared with antithrombotic drugs. Two-dimensional transoesophageal echocardiography (2D TEE) has become the election technique for guiding patent foramen ovale closure. Real-time Three-dimensional transoesophageal echocardiography (3D TEE) may be potentially superior to 2D TEE in the accurate assessment of the morphology and efficacy of transcatheter closure devices because of a better spacial orientation.
