During admission for investigation of dysphagia, an 82-year-old woman suddenly complained of dyspnea, which was followed by cardiogenic shock. Her symptoms, electrocardiogram, echocardiogram and laboratory data were compatible with an extensive acute anterior myocardial infarction. Emergency cardiac catheterization showed no atheromatous narrowing in any coronary artery. However, the contractions of the left and right ventricles were diffusely and severely impaired, except for some hyperkinesis of the basal area. The asynergy, as well as the abnormalities on the ECG, improved almost to normal by the 35th hospital day. An endomyocardial biopsy from the right ventricle during the acute phase showed atypical myocardial damage with proliferation of fine collagen fibers and small round-cell infiltration including polymorphologic leukocytes. This type of transient cardiac disorder has recently been described in Japan, and is called 'Tako-tsubo cardiomyopathy' because of the characteristic appearance of the left ventricular asynergy. In the present case, ventricular asynergy was not limited to the left ventricle, but was also present in the right ventricle.
