Takotsubo cardiomyopathy (TC) is a non-ischemic cardiomyopathy that is accompanied by sudden left ventricular myocardial stunning, dilation and dysfunction. It often results from severe emotional or physical stress. We present the case of a 41-year-old female patient who had general anesthesia induced uneventfully for an elective bladder sling procedure. After an intravaginal injection of local anesthesia (lidocaine 2%; epinephrine 1:100,000) just prior to the surgical incision, the patient had cardiovascular collapse for which cardiopulmonary resuscitation (CPR) was performed. The patient was eventually stabilized but transesophageal echocardiography showed impairment in cardiac motion and remarkably reduced ejection fraction. Troponin levels were elevated but coronary angiography was unremarkable. The ejection fraction returned to normal the next day. Local anesthetic with epinephrine administration can lead to TC, and with optimal management, long-term cardiac sequela can be avoided.
