MURGUIA-ARANDA, Abel et al. Takotsubo (stress cardiomyopathy) syndrome and inappropriate antidiuretic hormone secretion. Cir. cir. [online]. 2021, vol.89, n.3, pp.394-398.  Epub 03-Nov-2021. ISSN 2444-054X.  https://doi.org/10.24875/ciru.20000977.

Takotsubo syndrome is a form of acute reversible left ventricular dysfunction in the absence of coronary obstruction. An 85-year-old lady with a medical history of transcatheter aortic valve replacement was readmitted complaining of 2 weeks of severe pain by a displaced hip and failed osteosynthesis. While she was scheduled for hip surgery, severe hyponatremia secondary to inappropriate antidiuretic hormone secretion was documented, and sudden-onset pulmonary edema ensued. Echocardiography confirmed normally functioning aortic prosthetic valve and classical features of Takotsubo. She was treated with non-invasive mechanical ventilation, water restriction, and diuretics. Hyponatremia and the cardiomyopathy resolved and the patient recovered completely.
