Inverse Takotsubo Syndrome Resulting from a Fall, Malleolar Fracture, Anesthesia, Surgery, or Complicating Pulmonary Embolism?

To the Editor: The interesting case report of Lee et al. published in the December 2013 issue of the Journal, of a 43-year-old woman who suffered inverted takotsubo syndrome (TTS) (left ventricular apical hyperkinesis with midventricular and basal hypokinesis/akinesis) in the setting of complicating pulmonary embolism (PE), following surgery for a malleolar fracture, managed surgically under spinal anesthesia, spurs one to delve in the real cause of TTS in this patient; accordingly one wonders whether the emotional upheaval (with consequent adrenerergic sympathetic surge) from falling from a ladder, physical stress of pain from suffering a malleolar fracture, spinal anesthesia, surgical management of the fracture, or PE, all, or one or more of the above, in any combination, was the actual trigger of TTS in this otherwise healthy woman. More and more cases of TTS following PE are being reported in the literature, but TTS is also common in association with accidents, pain, fractures, anesthesia, various invasive procedures, and surgery, as can be shown by browsing the large research output on TTS. The present case reminds one about the ambivalence in attributing a case of TTS to a urological instrumentation, or the resultant sepsis, in a recently published report. The electrocardiogram (ECG) included in this case report is not of much help to ascertain the onset of TTS (ST-segment elevation and attenuation of the voltage of the QRS complexes, early in the illness, with deep T-wave inversions with QTc prolongation in Letter to the Editor
