Transient semi-circumferential mid-ventricular ballooning: An atypical variant of takotsubo cardiomyopathy

Abstract

Although apical ballooning is the most common morphological type of takotsubo cardiomyopathy, variants have been reported. Several case reports have demonstrated focal takotsubo cardiomyopathy. Most cases had left ventricular wall motion abnormality in the anterolateral segment. We present a case of focal ventricular ballooning localized especially in the inferior mid-ventricular segment.<Learning objective: Focal takotsubo cardiomyopathy localized especially in the inferior mid-ventricular segment is rare. However, it is important to distinguish focal takotsubo cardiomyopathy from acute coronary syndrome because patient follow-up and medical management are different. Cardiac magnetic resonance imaging is useful to make a definitive diagnosis for focal takotsubo cardiomyopathy.>
