Résumé
Objective: Few cases of Takotsubo cardiomyopathy with apical hypertrophic cardiomyopathy (APH)-like morphological changes during the recovery process have been reported.Patient: A 56-year-old woman diagnosed with Takotsubo cardiomyopathy showed a morphology similar to that of APH during recovery. We examined this patient using 2D speckle-tracking echocardiography based on the method used for hypertrophic cardiomyopathy, which suggested that the circumferential strain (CS) of the middle wall indicated myocardial function of the left ventricle, and the CS of the inner wall was associated with left ventricular chamber function.Results: We measured the CS of the endocardial, middle, and epicardial layers and found that the apical inner layer CS (CSinner), middle layer CS, and outer layer CS were all decreased at the onset. CSinner showed a strong tendency to recover on echocardiography performed when APH-like morphology was observed.Conclusion: The morphology of the apex in our case likely contributed to the maintenance of chamber function.
