Strain imaging is a sensitive marker of myocardial dysfunction and may be underused in Takotsubo cardiomyopathy (TC). We present a case of biventricular TC in which early improvement in left ventricular longitudinal strain predated subsequent improvement in ejection fraction. Early temporal patterns of strain of the left and right ventricles have not previously been described in TC. Our case illustrates how strain can be a sensitive marker for myocardial dysfunction and recovery in TC. Increased use of strain in TC may have further implications on prognosis and management.
应变成像技术是心肌功能障碍的一个敏感指标，在应激性心肌病（TC）中可能未得到充分利用。我们报告一例双心室TC病例，其中左心室纵向应变的早期改善早于射血分数随后的改善。此前尚未在TC中描述过左、右心室应变的早期时间模式。我们的病例说明了应变如何能够成为TC中心肌功能障碍和恢复的敏感指标。在TC中更多地使用应变技术可能会对预后和治疗产生进一步影响。
