Figure 1.
A. Apical two-chamber transthoracic echocardiography view showing no
obvious vegetation.
B. Bicommissural transesophageal echocardiography view showing a mobile
vegetation (arrows) on the surface of left ventricular muscle just below
the anterolateral commissure of the mitral valve.
C. Resection of the vegetation approached from aortic valve was
performed on the seventh day of hospitalization. Surgical findings show
a vegetation (arrows) on the surface of left ventricular muscle and
subvalvular tissue just below the anterolateral commissure of the mitral
valve.
D. A histological examination of the vegetation shows extensive
inflammatory cell infiltration with fibrin precipitation and necrotic
tissue (hematoxylin and eosin, original magnification x 100).
E. 18-Fluorodeoxyglucose positron emission tomography shows no evidence
of abnormal accumulation in left ventricular muscle.
F. gallium-67 scintigraphy shows no evidence of abnormal accumulation in
left ventricular muscle.
LA = Left atrium; LV = left ventricle.
