Takotsubo Cardiomyopathy in an Adult Woman With Repaired Tetralogy of Fallot

Abstract

Takotsubo cardiomyopathy is a reversible form of cardiomyopathy rarely reported in the adult congenital patient. We describe a case of a 49-year-old woman with repaired tetralogy of Fallot who presented with acute dyspnea. A 12-lead electrocardiogram revealed diffuse anterolateral T-wave inversion suggestive of myocardial ischemia. Cardiac catheterization was performed, demonstrating angiographically normal coronary arteries. A cardiovascular magnetic resonance examination showed apical akinesis with associated myocardial edema, but no myocardial damage on late gadolinium enhancement imaging, which is a characteristic of Takotsubo cardiomyopathy. The patient was treated medically. A follow-up echocardiogram demonstrated normalization of left ventricular systolic function and apical wall motion abnormalities.
