Answer

Transthoracic (TTE) or transesophageal echocardiography (TEE) can evaluate for a cardioembolic source or for risk factors such as patent foramen ovale. A 12-lead ECG should be performed as soon as possible after TIA to evaluate for dysrhythmias such as atrial fibrillation. Cardiac monitoring (inpatient telemetry or Holter monitoring) may be useful in patients without a clear diagnosis after initial brain imaging and ECG.
