Aortic arch (AA) atheroma is a common source of artery-to-artery embolism. Identification of AA atherosclerotic disease is an important component of the embolic stroke workup. Transesophageal echocardiography (TEE) is the gold standard for AA evaluation, but it has associated risks and is not always readily available. Computed tomography angiography (CTA) is a rapid and noninvasive alternative. This study was conducted to compare the sensitivity and specificity of CTA and TEE for detecting AA… CONTINUE READING
