Nightmare-Induced Atypical Midventricular Tako-Tsubo Cardiomyopathy

Figure 2

Echocardiographic images taken during ventricular systole from the parasternal long-axis view (top panel) and short-axis view (bottom panel), showing akinesia of the middle segment of the ventricular septum (arrows). Note the lack of systolic thickening of the akinetic segment, as compared to the others. IVS: interventricular septum; LA: left atrium; LV: left ventricle; MV: mitral valve; PW: posterior wall of the left ventricle; RA: right atrium; RV: right ventricle.
