Abstrakt: Dobutamine stress echo (DSE) is a valuable technique in the assessment of coronary artery disease (CAD). However, its role is limited when transthoracic (TTE) images are suboptimal. Transesophageal echo (TEE) may overcome this limitation due to less acustic impedance. To define the value of Dob-TEE in assessing CAD, 60 pts (54 male; 6 female; mean age 59±13 yrs) underwent near-simultaneousDob-TTE and Dob-TEE in the same setting. Elective coronary angiography was performed within 5 days. HE and TEE were performed at rest, during Dob infusion and 3min after recovery. Dob was infused in 3-min increments from 5 to 40mcg/kg/min. Atropine (0.5–1.0mg) was added in case of insufficient chronotropic response to Dob (85% predicted heart rate). Segments of the LV either from HE orTEE were grouped according to the 3 main coronary artery distributions. DSE was considered abnormal if new or worsening of segmental wall motion abnormalities (SWMA) were noted.
