The cardiomyopathy has got this name because the outline of the left ventricle looks like the octo-pus trap. TTC is usually induced by physical triggers, emotional triggers, both of them or neither of them some-times. The patients of TTC usually present the symptoms just like acute myocardial infarction or heart failure. Coronary angiography and left ventriculography are able to make the diagnosis and differential diagnosis. Although we have already good recognition of TTC, it might occur to the patients unexpectedly and sometimes preclude early diagnosis of it.展开更多
