Figure and Movie Legends
Figure 1A-B. The apical 4ch (A) and parasternal short axis (B)
transthoracic echocardiography images showed mass-like thickening of the
septal myocardium (arrows) which nearly obscured the RV cavity. It also
protruded toward LV cavity.
Figure 2A-C. The short axis T2 weighted (A) and transversal T1
weighted (B) CMR images showed significant myocardial thickening
isointense to the normal myocardium. However, T1 mapping (C) clearly
shows its heterogeneous signal intensity within the mass center.
Figure 3A-B. Late gadolinium images of short axis (A) and 4 ch
(B) images showed heterogeneously enhancing mass with its
necrotic/hemorrhagic center (asterix).
Movie 1A-B. The apical 4ch (A) and parasternal short axis (B)
transthoracic echocardiography images showed mass-like thickening of the
septal myocardium.
Movie 2A-B. The 3ch and 4ch cine images of CMR showed mass-like
isointense myocardial thickening apparently obscuring both ventricle
apices.
Movie 3. First-pass gadolinium perfusion study showed intense
enhancement of the mass and the necrotic core.
