Abstract Transesophageal echocardiography (TEE) has been the procedure of choice for identifying thoracic aortic atheromas. All patients over a 2-year period who underwent both TEE and magnetic resonance angiography of the thoracic aorta within 1 month were identified. The largest plaque in 3 aortic segments (ascending, arch, and descending) was measured. Thirty patients (16 men; 66.8 +/- 12.9 years) were studied. The mean size of the atheromas in the arch was larger as measured by TEE compared with magnetic resonance angiography (3.4 vs 1.4 mm, P =.01). However, the mean atheroma size was similar in the ascending aorta (1.9 vs 1.3 mm, P =.5) and descending aorta (3.9 vs 3.5 mm, P =.66). Of 24 aortic segments with plaques measuring >/=5 mm (with high embolic risk), 22 (92\%) were seen on TEE and only 13 (54\%) on magnetic resonance angiography (P =. 003). In conclusion, although both techniques are complementary, TEE does identify more high-risk plaques.
