Figure. An approach to the diagnostic use of echocardiography (echo). Rx indicates prescription; TEE, transesophageal

echocardiography; and TTE, transthoracic echocardiography. *For example, a patient with fever and a previously known heart murmur

and no other stigmata of infective endocarditis (IE). †High initial patient risks include prosthetic heart valves, many congenital heart

diseases, previous endocarditis, new murmur, heart failure, or other stigmata of endocarditis. ‡High-risk echocardiographic features

include large or mobile vegetations, valvular insufficiency, suggestion of perivalvular extension, or secondary ventricular dysfunction (see text).
