A 76-year-old woman with chronic lymphocytic leukemia was admitted to the intensive care unit for septic shock with E. coli bacteremia of unknown origin treated with cefotaxime and amikacin. She developed multi-organ failure with left ventricular dysfunction. Norepinephrine infusion was required for 4 days. ECG demonstrated sinus tachycardia without any sign of myocardial ischemia. Using transthoracic echocardiography (TTE), the left ventricular ejection fraction (LVEF) was measured at 40%. CT scan performed on admission did not show any morphological cardiac abnormality (Fig. 1).
