Abstract

Approximately 20% of patients with Takotsubo syndrome (TTS) develop complications such as left ventricular outflow tract obstruction (LVOTO). The published data suggest that a significant proportion of these patients have predisposing septal hypertrophy or sigmoid septum. However, the pathophysiology regarding this connection has not yet been fully elucidated. We herein present the case of a 75-year-old female patient with TTS complicated by LVOTO, which was successfully managed. During the follow-up, mild basal septal hypertrophy was observed. Subsequent exercise and dobutamine stress echocardiography were performed to reveal the mechanism of LVOTO in TTS.

乙状结肠隔：Takotsubo综合征左心室流出道梗阻的旁观者或贡献者- 1例报告并文献复习。

约20%的Takotsubo综合征（TTS）患者出现左心室流出道梗阻（LVOTO）等并发症。已发表的数据表明，这些患者中有相当大比例的人易患鼻中隔肥大或乙状结肠。然而，关于这种联系的病理生理学尚未完全阐明。我们在此报告一例75岁女性TTS合并LVOTO的病例，并成功处理。在随访中，观察到轻度基底间隔肥大。随后进行运动和多巴酚丁胺应激超声心动图，以揭示TTS中LVOTO的机制。
