Patent foramen ovale and stroke

About a quarter of the adult population is known to have a patent foramen ovale, rarely accompanied by the presence of an interatrial septal aneurysm. A patent foramen ovale is found in more than 40% of patients younger than 60 years who had a cryptogenic ischemic stroke. Clinical and echocardiographic parameters allow the identification of patients at high risk of recurrence after a first cryptogenic stroke even if treated with Aspirin. A multidisciplinary approach allow the selected patients to benefit of a correction of their cardiac anomaly with promising long term results.
