takotsubo cardiomyopathy

Reversible dysfunction of the left ventricle. It may be the cause of transient heart failure that occurs after exceptionally stressful events. The heart in such instances takes on a rounded shape with a narrow neck, resembling a traditional Japanese lobster trap (takotsubo). It is informally called broken-heart syndrome.
Synonym: apical ballooning syndrome; stress-induced cardiomyopathy; transient left ventricular apical ballooning
