We thank El-Battrawy et al for their interest in our article entitled “Takotsubo-Like Myocardial Dysfunction in Ischemic Stroke: A Hospital-Based Registry and Systematic Literature Review.”1
Takotsubo syndrome mostly presents with typical apical ballooning, but variants have been reported. Right ventricular (ie, biventricular) Takotsubo syndrome is gaining recognition because of the likelihood of poor outcome.2
In our study, right ventricular involvement was defined as any wall-motion abnormality (akinesis, hypokinesis, or dyskinesis) on transthoracic echocardiography. On the basis of the above definition, biventricular Takotsubo-like myocardial dysfunction (Bi-TMD) developed in 6 patients (26.1%), and it was included in only typical TMD group, not atypical. These patients had uniform involvement of the apical or mid- to-apical right ventricular wall. …
