Although left ventriculography was originally used to detect its unique morphology mimicking "takotsubo", echocardiography is currently an essential imaging modality to detect segmental as well as global wall motion abnormalities in patients with TTS. In addition, a study using cardiac magnetic resonance imaging revealed the presence of right ventricular involvement in 81 of 239 (34%) TTS patients [35] . First, left ventricular outflow tract obstruction (LVOTO) may develop in TTS patients with apical ballooning and a hyperkinetic basal wall motion (Fig. 6) . Transient left ventricular apical ballooning without coronary artery stenosis: a novel heart syndrome mimicking acute myocardial infarction Biventricular takotsubo cardiomyopathy with asymmetrical wall motion abnormality between left and right ventricle: a report of new case and literature review	./cache/cord-353515-92qqucyl.txt	./txt/cord-353515-92qqucyl.txt
