Supplemental Videos
Four supplemental videos in .MOV format.
Files in this Data Supplement:
Video 1
-
Typical bFFE four-chamber cine-loop of a normal human subject. Notice the invariance of the pericardial boundary at all times of the cardiac cycle.
Video 2
-
Typical bFFE short-axis cine-loop of the same subject as Animation 1. Notice the invariance of the pericardial boundary at all phases of the cardiac cycle. Notice also how the center of the LV chamber remains fixed throughout the cardiac cycle.
Video 3
-
Four-chamber cine-loop of the subject with congenital absence of the pericardium. Notice the great variation of the epicardial boundary compared to Animation 1.
Video 4
-
Short-axis cine-loop of the subject in Animation 3. Notice the motion of
the LV lateral wall, and notice how much the center of the LV chamber oscillates throughout the cardiac cycle compared to Animation 2.
