Takotsubo Cardiomyopathy


Takotsubo cardiomyopathy (TTC) has gained more recognition since its first description in 1990 by Satoh et al. The word takotsubo refers to the Japanese octopus trapping pot with a large round base and narrow neck, which is the characteristic shape of the left ventricle (LV) in this syndrome, although other morphologies have since been described. TTC is known by many names including stress cardiomyopathy, broken heart syndrome, apical ballooning syndrome and ampulla cardiomyopathy. It is a reversible form of cardiomyopathy that presents clinically as an acute myocardial infarction (MI) triggered by an emotionally or physically stressful event. An abnormal response to a catecholamine surge leads to TTC and a stressor can be identified in a majority of cases. TTC occurs at a significantly higher frequency in post-menopausal women with 80–85 % of all cases presenting in women. Less than 3 % of cases occur in those less than 50 years of age.
