Coronary arteriograms were also obtained. Three falsepositive results compared with 28 true-positive cases resulted in a specificity of 90\% for two-dimensional echocardiography; 3 patients had normal echocardiograms in the presence of significant angiographic lumen narrowing. Since 9 patients had left main trunk disease, sensitivity was 67\%. Our findings suggest that twodimensional echocardiography is somewhat limited in permitting visualization of left main coronary artery disease.}, issn = {0891-1150}, URL = {https://www.ccjm.org/content/51/1/7}, eprint = {https://www.ccjm.org/content/51/1/7.full.pdf}, journal = {Cleveland Clinic Journal of Medicine} }
