An 82-year-old woman experienced sudden cardiac dysfunction mimicking myocardial infarction. This case highlights Tako-tsubo cardiomyopathy affecting both ventricles, a transient cardiac disorder.

Area of Science:

  • Cardiology
  • Pathology

Background:

  • A case study of an 82-year-old woman presenting with acute cardiogenic shock and symptoms mimicking myocardial infarction.
  • Initial investigations including ECG and echocardiogram suggested extensive acute anterior myocardial infarction.

Observation:

  • Emergency cardiac catheterization revealed no coronary artery narrowing.
  • Diffuse, severe impairment of left and right ventricular contractions was observed, with basal hyperkinesis.
  • Endomyocardial biopsy showed atypical myocardial damage with collagen proliferation and inflammatory cell infiltration.

Findings:

  • The patient's condition, including ventricular asynergy and ECG abnormalities, significantly improved by the 35th hospital day.
  • This presentation aligns with Tako-tsubo cardiomyopathy, a transient cardiac disorder.

  • Notably, ventricular asynergy extended to both the left and right ventricles, unlike typical descriptions.

    • Implications:

    • This case expands the understanding of Tako-tsubo cardiomyopathy, demonstrating its potential to affect both ventricles.
    • It underscores the importance of considering non-atherosclerotic causes of acute cardiac dysfunction.
    • Further research into the pathophysiology and diagnostic criteria for biventricular Tako-tsubo cardiomyopathy is warranted.
