Why the study?
Does transesophageal echocardiography improve the detection of cardioembolic sources and alter therapy in patients with focal cerebral ischemia of unknown cause, sinus rhythm, and nondiagnostic TTE?

May support TEE for embolic source detection after nondiagnostic TTE in cryptogenic stroke; leaves open whether routine use improves outcomes.
Does transesophageal echocardiography improve the detection of cardioembolic sources and alter therapy in patients with focal cerebral ischemia of unknown cause, sinus rhythm, and nondiagnostic TTE?
TEE provides significant diagnostic yield and can alter clinical management in patients with cryptogenic stroke and nondiagnostic TTE.
