Legend Figure 1
Transesophageal echocardiogram. (A) Bicaval view demonstrating the left
atrial mass attached to the atrial septum. (B) Mid esophageal 120° view
showing the dynamic obstruction of the mitral valve by the mass. RA,
right atrium; LA, left atrium; LV, left ventricle.
Legend Figure 2
Four chamber post-contrast cardiac magnetic resonance imaging revealing
the left atrial mass (asterisk). LA, left atrium; LV, left ventricle.
Legend figure 3
Thoracoscopic view of the reddish and slightly gelatinous mass attached
to the left side of the interatrial septum. LA, left atrium; RA, right
atrium; IA septum, interatrial septum; Asterisk, mass.
Legend figure 4
Scattered stellate and spindle cells without abnormal mitotic figures in
abundant loose myxoid matrix suggesting the diagnosis of cardiac myxoma
(Stain: H&E, ×10).
Legend figure 5
Post- contrast cardiac MRI showing the recurrence of the left atrial
mass attached to the interatrial septum in 4 chambers view (A) and short
axis view (B). Asterisk, mass.
Legend figure 6
Resected yellowish, slightly lobulated left atrial mass with a part of
the atrial septum
Legend figure 7
(A) Histopathology pictures of cardiac intimal sarcoma showing spindle
cells in fascicles with nuclear pleomorphism and mitotic figures (Stain:
H&E, ×10). (B) Immunohistochemistry profile shows positivity for MDM2.
