case_images: Ventriculography showing two finger-shaped images with contrast penetration in the
  inferior wall during different phases of cardiac cycle (A,
  proto-diastole; B, tele-diastole; C, proto-systole;
  and D, tele-systole).

case_images: At ventriculography, two finger-shaped images with contrast penetration were observed in the inferior wall (Figure 1 and Supplementary material online, Video S1).
case_images: Echocardiographic features of myocardial crypts. (A) Transthoracic
  echocardiogram two-chamber view showing diastolic features of a myocardial crypt:
  penetration perpendicular to myocardial wall and contention by thin sub epicardial layer
  (white arrow); (B) systolic sub-total obliteration on transthoracic
  echocardiogram two-chamber view; and (C) modified two-chamber view
  demonstrates the presence of second, more apical crypt parallel of the previous one
  (white arrow).

case_images: Two fissure-like protrusions penetrating more than 50% of the wall thickness, contained by a thin sub epicardial layer and with sub-total obliteration during systole, were confirmed on the mid-inferior wall (Figure 2 and Supplementary material online, Videos S2 and S3).
case_images: (A) Optimal delineation of the two crypts in cardiac magnetic
  resonance two-chamber view sequence (black arrows) and (B) obvious
  hyperenhancement in the inferior wall (white arrows) with adjacent myocardial crypt
  (open arrow) on the cardiac magnetic resonance-late gadolinium enhancement short-axis
  sequence.
