BACKGROUND It has been suggested that prominent Eustachian valve (EV) and Chiari's network (CN) predispose to paradoxical embolism but their presence in patients with presumed paradoxical stroke is not always easily detectable by transesophageal echocardiography (TEE). We sought to prospectively assess the frequency of EV/CN as assessed by intracardiac echocardiography (ICE) in patients submitted to patent foramen ovale (PFO) transcatheter closure in order to investigate their role in… CONTINUE READING
