To the editor: I enjoyed the excellent paper by DeMaria, King, Sale, et al, "Echography and Phonography of Acute Aortic Regurgitation in Bacterial Endocarditis" (Ann Intern Med 82:329-335, 1975). In Figure 4 of that paper, an echocardiogram shows thick diastolic echoes, supposedly representing aortic valve vegetations. These echoes viewed with their connecting systolic echoes appear very similar to a thickened anterior leaflet of the mitral valve. Such an effect can be produced if the transducer is directed midway between the mitral valve and the aortic root. The authors did not show an echocardiogram of the mitral valve from this patient
