OBJECTIVE: To assess the usefulness of transesophageal @entity452 stress echocardiography (TEDSE), to identify @entity1 with @entity453 . METHODS: @entity1 referred for TEDSE with coronary angiography were included. Images were digitized in systolic cine-loop at baseline, with low dose- @entity452 (14.4 +/- 5 micrograms/kg/min), with high dose- @entity452 (28.7 +/- 10.5 micrograms/kg/min) and during recovery, and then analyzed by two observers. The left ventricle was divided into 16 segments according to coronary distribution, and the study was considered abnormal if there was a new or worsening of the segmental wall motion abnormality. Quantitative coronary angiographies were independently assessed, and lesions considered significant if they had > or = 70% diameter stenosis. RESULTS: Sixty eight @entity1 were included. TEDSE sensitivity, specificity, and accuracy were 93%, 89.7%, and 91.1%, respectively. TEDSE correctly detected 7/7 single @entity66 and 20/22 multiple @entity66 @entity1 . Twelve-lead ECG had a sensitivity, specificity, and accuracy of 38.3%, 91.8%, and 74.5% respectively, to detect the same lesions. CONCLUSIONS: TEDSE is feasible, safe, sensitive, and specific to detect significant coronary lesions. It should be considered in @entity1 with suboptimal acoustic window or poor visualization of endocardial borders.
