Answer

Color Doppler valve analysis during transesophageal echocardiography (TEE) can be used to accurately diagnose bicuspid aortic valve in patients with severe symptomatic aortic stenosis, according to a prospective study of 51 patients. In detecting bicuspid aortic valve, color Doppler TEE had a sensitivity of 95.5%, a specificity of 96.5%, and a positive predictive value of 95.5%. [21]
