Tako-Tsubo cardiomyopathy

Tako-Tsubo cardiomyopathy usually mimics an acute coronary syndrome and is defined as a transient left ventricular systolic dysfunction. Stress is frequently present, but is not systematically found. Diagnosis is based on the criteria of the Mayo-Clinic. Tako-Tsubo cardiomyopathy preferentially affects postmenopausal women. Several explorations are performed to confirm the diagnosis: electrocardiogram, biomarkers, echocardiography, coronary angiography and left ventricular angiography, and MRI. Left ventricular dysfunction is pathognomonic, with circular akinesia regarding the different mid and apical segments of the left ventricle in its typical form. Complications may occur in the acute phase and should be systematically assessed. The complete recovery of left ventricular systolic dysfunction is the rule and must be assessed, allowing to confirm the diagnosis of Tako-Tsubo cardiomyopothy.
