Objective: Takotsubo stress cardiomyopathy is characterized by dysfunction of the left ventricle of the heart including apical ballooning and focal wall-motion abnormalities. Although reported in association with seizures and intracerebral hemorrhage, there are no studies reporting its occurrence in patients having stereoelectroencephalography (sEEG).

Methods: A 38-year-old lady with no prior history of cardiac disease experienced sudden onset chest pain and acute left ventricular failure 4 hours following explantation of stereoelectroencephalogram electrodes.

Results: A small parenchymal hematoma related to the right posterior temporal electrode had been noted postelectrode insertion but was asymptomatic. Focal-onset seizures from nondominant mesial temporal structures were recorded during sEEG. Following the presentation with LVF, new-onset anterolateral T-wave inversion with reciprocal changes in leads II, III, and aVF was noted on electrocardiogram (ECG) and the chest X-ray findings were consistent with pulmonary edema. Echocardiography demonstrated hypokinesis of the cardiac apex and septum consistent with Takotsubo stress cardiomyopathy.

Significance: Awareness of the possible complication of Takotsubo stress cardiomyopathy is required in an epilepsy surgery program.
