Description
Summary:The goal of this study was to determine the feasibility, safety, sensitivity and specificity of transesophageal dobutamine stress echocardiography for the detection of coronary artery disease. Dobutamine stress echocardiography has been shown to be an extremely sensitive and specific noninvasive technique for the detection of myocardial ischemia. However, inadequate transthoracic images preclude the use of dobutamine stress echocardiography in a small but significant group of patients. Transesophageal echocardiography provides better resolution than that obtained with routine transthoracic imaging. Patients scheduled for routine cardiac catheterization underwent transesophageal dobutamine stress echocardiography. All patients underwent coronary arteriography within 48 h of the study, and lesion severity was determined by quantitative coronary angiography. Significant coronary obstruction was defined as stenosis >50%. Fifty-one male patients were enrolled in the study; six were excluded for technical reasons. There were no adverse outcomes or complications. Of 27 patients with significant coronary artery disease, 22 had positive study results (sensitivity 82%). Of 13 patients without significant obstructive coronary disease, I had a false positive study result (specificity 93%). In patients with a minimal lumen diameter 80%, and in patients with a minimal lumen diameter >1.5 mm, sensitivity was
