This ventriculogram shows the typical apical ballooning of the left ventricle during Takotsubo myocardiopathy.  This serious condition can be caused by extreme stress, such as in the death of a loved one, or prolonged high stress levels.  The ECG will usually show ST elevations indicating an anterior wall M.I., but the angiogram will show no arterial occlusions.  Takotsubo myopathy causes a sudden onset of congestive heart failure.  It is transient, and those who survive it generally recover fully.  For an excellent and complete discussion of Broken-Heart Syndrome, go to Wikipedia.  If you are viewing with a mobile device, and are having difficulty getting the video to play, go to this YouTube link.
