Transcranial Doppler in the diagnosis of cardiac patent foramen ovale.
Right-to-left shunt due to patent foramen ovale is a well-established risk factor for ischemic stroke, especially in young subjects and in patients with cryptogenic stroke. We report a detailed method for the diagnosis of a right-to-left shunt by means of transcranial Doppler as established at a recent consensus conference, and review the literature on the indications for the test.
