takotsubo cardiomyopathy (ttc) is increasingly being recognized as a form of acute reversible myocardial stunning in the setting of unobstructed coronary arteries. The Japanese term “Tako tsubo”—literally “octopus trap”—derives from the angiographic appearance of the left ventricle (LV) at end-systole with marked “ballooning” of the apex and hypercontractile base. It occurs most often in post-menopausal women as a response to emotional stress. The presentation with chest pain, electrocardiographic (ECG) changes and, sometimes, LV failure may result in a misdiagnosis of acute coronary syndrome. With the advent of primary percutaneous coronary intervention (PCI), this cardiomyopathy is increasingly seen. The defining hallmark of TTC is the complete recovery of function that occurs within days to weeks of the original clinical presentation. Cardiologists need to be aware of the specific diagnostic features of the condition and the contribution that imaging may make to its recognition and management.Figures 1–7⇓⇓⇓⇓⇓⇓⇓
