title: Detection of atherosclerotic lesions in the aorta by transesophageal echocardiography.
abstract: Transesophageal echocardiographic studies were prospectively performed in 152 consecutive patients older than age 40 years referred to the echocardiography laboratory to assess the prevalence of atherosclerosis in the thoracic aorta and relate this to a history of systemic embolization. Forty-four patients (29%) had at least 1 atherosclerotic lesion in the thoracic aorta. This was associated with a higher prevalence of coronary artery disease (78% of all patients with coronary artery disease), carotid artery disease (88% of all patients with carotid artery disease) and peripheral vascular disease (all symptomatic patients). Forty-two of all patients (28%) had systemic emboli, 20 (48%) of whom had at least 1 atheromatous lesion in the thoracic aorta. Conversely, only 24 of 110 patients (22%) without previous systemic emboli had atheromatous lesions (p < 0.001). It is concluded that atherosclerotic lesions in the thoracic aorta can readily be identified with transesophageal echocardiography. The detection of atherosclerotic plaques of the aorta represents a marker of diffuse atherosclerotic disease, often associated with carotid, coronary and peripheral vascular disease and with the occurrence of systemic emboli. Transesophageal echocardiography may be used serially to investigate whether dietary or pharmacologic maneuvers, or both, can shrink established atherosclerotic plaques in the thoracic aorta.
