Right ventricular involvement in Takotsubo cardiomyopathy

Takotsubo syndrome (TS) is characterized by a transient apical ballooning of the left ventricle, reversible ST-T-segment abnormalities and mildly elevated troponin without coronary artery stenosis, mimicking myocardial infarction (MI). Originally described as a disturbance of the left ventricle, recently an involvement of the apex of the right ventricle (RV) has been recognized affecting approximately one-quarter of cases.
