Core Tip
Core tip: Patent foramen ovale (PFO) is an emerging etiology of cryptogenic stroke, and PFO closure therapy has been shown to reduce the rate of recurrent stroke. Detection of the air embolic signal by transcranial Doppler (TCD) after injection of agitated saline bubbles at the antecubital vein will help to confirm the importance of PFO as the cause of a concurrent stroke. In addition, the automated embolic signal detection method should further facilitate use of TCD for air embolic signal detection after the agitated saline bubbles injection in patients with cryptogenic stroke and PFO.
