Modification of Diagnostic Criteria in Takotsubo Syndrome

pp 79-81

Abstract

Takotsubo syndrome (TTS) is characterized by transient
regional systolic dysfunction in the left ventricle.
The dysfunctional areas do not correspond to the coronary
artery perfusion territory and are often identified
in the circumferential apical, mid-ventricular, or
basal ventricle. This syndrome is a relatively novel
concept: the first report of TTS was described in 1990
by Sato, et al. in Japan. (1) Following this first case,
numerous TTS cases have been globally reported under
multiple names, such as stress cardiomyopathy,
apical ballooning syndrome, broken heart syndrome
and catecholamine induced cardiomyopathy. Since
then, although various data obtained from TTS cases
have been accumulated, controversies remain about
the diagnostic criteria. Arias et al. have reported the
clinical features of TTS in their hospital located in
Buenos Aires, Argentina. (2) Their report plays an
important role in the field of TTS, since most of the
registered data is originated from countries in the
northern hemisphere.
